Just for shits and giggles, here’s a tale I call the Stupid Sprinkler Saga, a string of events that happened over the last few weeks

So I bought a house back in spring. I’m still learning the ins and outs of home ownership, because I’ve only ever had apartments, and when something goes wrong in an apartment, it’s someone else’s job to fix it. I do not have this benefit anymore. And it is much more stressful, come to find out

So as this is the first winter I’ve lived in the house, and a few weeks ago my dad told me that, before the weather gets too cold, I should shut off the water to my sprinkler system and drain the pipes so they don’t freeze and potentially explode when the weather dips below freezing. He comes over to help me locate the valve that will cut off water to the sprinklers, and that it’s probably buried in the yard with a plastic lid covering it. We just have to figure out which one it is. 

He comes over. We search the yard. We cannot find the sprinkler valve. 

He comes over a second time for an errand and we search the yard again. Still can’t find it. But this was in November, we live in Texas, and we probably had a few weeks to months before it gets cold enough to freeze. 

In early December, the city sends me a letter saying I have to get my backflow preventer inspected. I find a guy on Google and he comes to do the inspection while I’m away for a con. 

A few weeks later, while I’m out of state for another con, I hear that we’re getting a crazy-big cold front in a few days and the temps will be dropping into the teens for a few days. I still haven’t figured out what to do about my sprinklers. Commence panik

By the time I get back from my trip I have about 48 hours before freezing temps set in. I call the sprinkler inspection guy and ask if he happened to see the sprinkler cutoff valve while he was doing the inspection. He said no. 

I spend several hours digging through Google and YouTube. “How to locate sprinkler cutoff valve”. “Where is my sprinkler cutoff valve?”. “How to drain sprinkler system”. “What if I can’t find my sprinkler shutoff?” etc. During my research I go out and search the yard and my house several times, following the advice of the videos and articles I was seeing. No dice. 

One article I saw suggested that, most of the time, a permit and blueprint for an in-ground sprinkler system has to be submitted to the city for approval before it’s installed. So the city might know where the valve would be. My house was built a while ago but it was the only light of hope I had at this point. I call the city. They tell me they don’t know where the valve is, but they can send a tech out to help me find it within the next few hours. Perks of living in a small town. 

A few hours later the water tech from the city arrives. He spends about 15 minutes searching my yard and asking me questions. He cannot locate the shutoff. He even tells me I might not have one. We find a valve that will shut off the water supply to my house hidden in the bushes, which would cut off the water to my sprinklers, but would also shut off the water inside my house. This was less than ideal. 

He spends another 10 minutes searching, and even talks to my neighbors who pull up while he’s digging around. The neighbors confirm that they have a sprinkler shutoff valve, and I should have one too, since our houses were built around the same time. The tech calls another tech in to help. The other tech arrives and there are now two city workers in my yard, plus me, all trying to figure out where the hell this valve is. 

And then we find it. In the stupidest place imaginable

A bit of backstory: My house has some very stupid quirks left from the previous owner that I’ve just.... put out of my mind in an “I do not percieve it” kind of way. There’s some random piles of rocks in the backyard from a half-finished landscaping project, the remnants of what I think was supposed to be a fire pit in the middle of the backyard, and, notably, a weird plastic canvas bag sitting on the fence line. The bag is old and gross and looks like it’s filled with some sort of white cotton stuff, and it’s been sitting and leaning against my fence since I moved in. I always thought it was either A) something gross I just didn’t want to mess with, and/or B) belonged to my neighbors, since it sat right against their fence line. And when the second tech got there, he went to mess with the bag.

The bag that turned out to be an insulated bag that was covering the damn sprinkler shutoff valve/backflow preventer. 

This piece of shit bag has been sitting at the edge of my yard since I moved in and no one knew what it was until a city worker realized it was perfectly in-line with the water meter on the street and must be covering something important. 

It took 4 people to figure this out

Sprinklers are stupid the end

Common Mistakes to Avoid During Sprinkler Systems Installation

When installing a sprinkler system, there are several common mistakes that can lead to inefficiency, water waste, or long-term maintenance issues. Here are some key mistakes to avoid:

Improper Sprinkler Head Placement Mistake: Placing sprinkler heads too close or too far from each other can lead to uneven coverage, dry spots, or overwatering. Solution: Ensure even head-to-head spacing, where the water from one head reaches the adjacent one for uniform coverage.

Incorrect Pipe Sizing Mistake: Using the wrong pipe size can cause pressure loss or excessive pressure, affecting the system’s performance. Solution: Use proper pipe sizing based on the flow rate and water pressure in your area. Too small pipes reduce water flow, while oversized pipes can be costly and unnecessary.

Not Accounting for Water Pressure Mistake: Failing to measure and adjust for local water pressure can lead to either low flow (underwatering) or high pressure (misting and inefficient watering). Solution: Test your home’s water pressure before installation. Use a pressure regulator if necessary to control the flow.

Skipping a Backflow Preventer Mistake: Failing to install a backflow preventer can lead to contamination of your home’s water supply with chemicals and fertilizers. Solution: Always install a backflow preventer to protect your water supply from contamination.

Overlooking Zoning Mistake: Installing all sprinkler heads on a single zone can lead to over- or under-watering specific areas, particularly when different plants or zones require different water levels. Solution: Divide your system into zones that match the specific watering needs of each area (e.g., sunny areas, shaded areas, or different types of plants).

Incorrect Valve Installation Mistake: Improper valve installation, such as positioning them too deep or too shallow, can make future maintenance difficult. Solution: Install valves in accessible, easy-to-locate spots, at a proper depth that ensures they are not easily damaged by foot traffic or landscaping.

Failing to Consider Soil Type Mistake: Ignoring the soil type can result in poor water absorption, runoff, or uneven watering. Solution: Adjust the sprinkler heads and watering times based on your soil type. For example, clay soils require slower, less frequent watering compared to sandy soils.

Neglecting Regular Maintenance Mistake: Failing to check for clogs, leaks, or misaligned heads can lead to water waste and reduced efficiency over time. Solution: Schedule regular inspections and maintenance to ensure the system is working properly, and clean or replace heads as needed.

Ignoring Seasonal Adjustments Mistake: Keeping the same watering schedule year-round can waste water during the cooler months and under-water during hot seasons. Solution: Adjust watering schedules seasonally and install a rain sensor or smart controller to automate these adjustments.

Incorrect Depth of Buried Pipes Mistake: Burying pipes too shallow can leave them exposed to damage from mowers or freezing temperatures, while burying too deep may lead to difficulties during repairs. Solution: Follow local codes for burying pipes, typically 6 to 12 inches deep, to avoid damage and freezing issues.

Avoiding these mistakes will help ensure that your sprinkler system operates efficiently and lasts for many years.

Performance Testing: How Stockton's Fire Sprinkler Contractors Conduct It

Introduction

Fire safety is corporate fire safety a critical aspect of protecting lives and property, and one of the key components of fire safety is a well-designed and properly functioning fire sprinkler system. In Stockton, California, fire sprinkler contractors play a crucial role in ensuring the effectiveness and reliability of these systems. Performance testing is an essential part of their work, as it allows them to evaluate the efficiency and functionality of fire sprinkler systems. In this article, we will explore how Stockton's fire sprinkler contractors conduct performance testing and the importance of their role in maintaining fire safety.

Performance Testing: How Stockton's Fire Sprinkler Contractors Conduct It

Performance testing is a comprehensive evaluation process that fire sprinkler contractors undertake to assess the effectiveness and reliability of a fire sprinkler system. This testing involves various procedures that aim to identify any issues or deficiencies in the system's design, installation, or maintenance. Let's dive deeper into how Stockton's fire sprinkler contractors conduct performance testing.

Preparation for Performance Testing: Before conducting performance testing, fire sprinkler contractors ensure that all necessary preparations are made. This includes gathering relevant information about the system, such as its design specifications, maintenance records, and any previous test results. They also inspect the system to identify any visible signs of damage or malfunction.

Water Flow Test: One of the primary tests conducted during performance testing is the water flow test. Fire sprinkler contractors measure the water flow rate from each individual sprinkler head to determine if it meets the required standards. They also check for any obstructions or blockages in the piping system that may affect water distribution.

Pressure Test: Another crucial aspect of performance testing is the pressure test. Contractors measure the water pressure within the system to ensure it falls within acceptable limits. They also examine pressure gauges, valves, and other components to identify any leaks or malfunctions.

Activation Test: To simulate real-life scenarios, fire sprinkler contractors conduct activation tests. This involves activating the sprinkler heads to assess their response time and coverage. Contractors closely monitor the activation process to ensure that all sprinkler heads function as intended and provide adequate water distribution.

Alarm Verification: Fire sprinkler systems are often interconnected with fire alarm systems. During performance testing, contractors verify that the alarm system is activated when the sprinklers are triggered. This ensures that occupants of the building are promptly alerted in case of a fire emergency.

Inspection of Supporting Equipment: In addition to evaluating the sprinkler system itself, fire sprinkler contractors also inspect supporting equipment such as pumps, control panels, and backflow preventers. They check for proper operation and ensure that all equipment is in good working condition.

Documentation and Reporting: After conducting performance testing, fire sprinkler contractors document their findings and prepare a deta

Common Mistakes to Avoid During Irrigation Winterization

Winterizing your irrigation system is essential to prevent damage and ensure it’s ready for the next growing season. However, even well-intentioned homeowners can make mistakes during the process. Here are some common mistakes to avoid during irrigation winterization to ensure your system stays in top condition.

Mistake 1: Failing to Turn Off the Water Supply

One of the most critical steps in winterizing your irrigation system is turning off the main water supply. Failing to do so can result in water continuing to flow into the system, leading to potential freezing and pipe damage. Ensure you locate and shut off the main valve before starting the winterization process.

Mistake 2: Inadequate Draining of the System

Draining the system is crucial to remove all water from the pipes, valves, and sprinkler heads. Common mistakes include:

Manual Drain Valves: Not opening all manual drain valves to allow water to flow out completely.

Automatic Drain Valves: Assuming automatic drain valves will handle all the draining without checking their functionality.

Blow-Out Method: Using insufficient air pressure or not blowing out each zone thoroughly. Always ensure each zone is clear of water.

Mistake 3: Neglecting to Insulate Exposed Pipes

Exposed pipes are highly susceptible to freezing temperatures. Neglecting to insulate these pipes can lead to cracks and bursts. Use foam pipe insulation or insulating tape to cover all above-ground pipes, and ensure that backflow preventers and other vulnerable components are protected.

Mistake 4: Overlooking System Leaks and Repairs

Before winter sets in, it’s essential to inspect your irrigation system for any leaks or damage. Overlooking these issues can result in worsening damage during the winter months. Perform a thorough inspection and address any necessary repairs promptly to maintain the integrity of your system.

Mistake 5: Not Disconnecting Hoses

Plumbing Devices to Prevent Backflow

Plumbing Devices to Prevent Backflow

are essential components in maintaining the integrity of potable water systems. These devices ensure that contaminated water from non-potable sources does not flow backward into clean drinking water supplies, thereby safeguarding public health. Here are several common types of backflow preventers and their applications:1. Reduced Pressure Zone (RPZ) ValveFunctionality: RPZ valves provide robust protection against both backpressure and backsiphonage. They incorporate two check valves separated by a zone of reduced pressure and a relief valve. If either check valve fails, the relief valve opens, discharging water to prevent contamination.Applications: RPZ valves are suitable for high-hazard situations where the potential for contamination is significant. They are commonly used in industrial facilities, hospitals, and commercial buildings where chemicals or pollutants are present.2. Double Check Valve Assembly (DCVA)Functionality: DCVAs consist of two independently operating check valves that prevent backflow by closing when flow direction reverses. They offer protection against backsiphonage but may not provide adequate protection against backpressure without an additional relief valve.Applications: DCVAs are typically used in medium-hazard applications such as irrigation systems, fire sprinkler systems, and some commercial plumbing installations.3. Atmospheric Vacuum Breaker (AVB)Functionality: AVBs prevent backsiphonage by allowing air to enter the water supply line when negative pressure occurs. They are designed to open and release air into the system, breaking the siphon and preventing contaminated water from entering the potable water supply.Applications: AVBs are suitable for low-hazard applications such as residential sprinkler systems, outdoor hose bibs, and similar installations where there is minimal risk of backpressure.4. Pressure Vacuum Breaker (PVB)Functionality: PVBs prevent backsiphonage by incorporating a spring-loaded check valve that closes when water flow reverses. They include an air inlet valve that opens during pressure drops, allowing air to enter and prevent siphoning.Applications: PVBs are commonly used in irrigation systems, outdoor plumbing fixtures, and other applications where there is a moderate risk of backflow.5. Hose Bib Vacuum Breaker (HBVB)Functionality: HBVBs are simple devices that attach to outdoor hose bibs or faucets. They prevent backsiphonage by incorporating a check valve that closes when water flow reverses, ensuring that contaminated water cannot enter the potable water supply.Applications: HBVBs are specifically designed for outdoor use and are required by plumbing codes to prevent contamination from garden hoses and other outdoor connections.6. Dual Check ValveFunctionality: Dual check valves consist of two check valves in series that prevent backflow by closing in the event of flow reversal. They are simpler devices compared to DCVAs but provide basic protection against backflow.

In conclusion, backflow preventers play a vital role in protecting potable water supplies from contamination. By selecting the right type of preventer for the application, following installation best practices, and conducting regular maintenance, you can ensure the reliability and effectiveness of backflow prevention measures in safeguarding public health and water quality.

Gate Valve: A Reliable Solution for Fluid Control

 Gate valves and check valves are two types of valves used in industrial and commercial applications, serving distinct purposes with unique characteristics.

They ensure a tight shut-off, isolating systems or pipelines. Gate valves suit applications requiring on/off control, like water distribution, oil and gas pipelines, and chemical processing.

Check valves are one-way valves that allow flow in one direction, preventing reverse flow. They prevent backflow in pump systems, compressor lines, and boilers. Check valves open with desired flow and close with reverse flow, ensuring system safety and efficiency.

Gate valves provide manual control, while check valves operate automatically based on flow direction. Gate valves suit tight shut-off and isolation, while check valves prevent backflow.

Both valve types play vital roles based on system requirements and flow control needs.

gate valves types :

Gate valves come in various types, each designed to suit different applications and operating conditions. The most common types of gate valves include:

Solid Wedge Gate Valves: These are the most basic and widely used type of gate valves. They feature a solid, tapered wedge that seals against the valve body when closed, providing a tight shut-off. Solid wedge gate valves have gained popularity in general industrial and commercial applications due to their simplicity, durability, and cost-effectiveness. Many users prefer them for their reliable performance and cost-efficient operation.

Flexible wedge gate valves: feature a flexible, articulating wedge that adapts to the valve body, creating a better seal when closed. These valves are ideal for applications with temperature variations or minor misalignment, as the flexible wedge can accommodate these changes.

Parallel slide gate valves: on the other hand, utilize two flat, parallel gates that slide against each other to open and close the valve. This design enables a streamlined flow path and reduced pressure drop, making them suitable for high flow rate applications with minimal flow resistance.

Double Disc Gate Valves: These valves incorporate two separate discs that create a tighter and more reliable seal when closing. They find extensive use in high-pressure or critical applications, where a robust shut-off is crucial. The choice of gate valve type depends on factors such as the handled fluid or gas, operating pressure and temperature, desired flow characteristics, and specific application requirements. Manufacturers offer a wide range of gate valve options to meet the diverse needs of different industries.

OS&Y gate valve :

OS&Y gate valves, also known as “outside stem and yoke” or “outside screw and yoke” gate valves, are widely used to control water flow in fire sprinkler systems. These valves have a gate that moves up and down to regulate the flow, with the stem and yoke mechanism positioned outside the valve body.

The operation of an OS&Y gate valve is simple: raising the gate allows water to flow freely while lowering the gate cuts off the water supply. When fully open, the valve provides an unobstructed flow path, resulting in minimal friction loss. This makes OS&Y gate valves an efficient choice for fire sprinkler system applications.

Butterfly gate valve:

Butterfly gate valves are unique valves that use a rotary disc mechanism instead of a sliding gate design. The circular disc rotates on a shaft to control fluid or gas flow by opening and closing the valve. These valves have become popular in industrial and commercial applications due to their compact size, lightweight nature, and quick operation. These valves are a preferred choice in situations where space constraints and quick response times are crucial factors.

Check valve VS gate valve :

Check valves and gate valves serve distinct purposes in fluid flow systems, though both play important roles in controlling and managing the movement of liquids and gases.

The primary function of a check valve is to allow flow in only one direction while preventing backflow. This makes check valves essential for applications where maintaining the proper flow direction is crucial, such as in pump systems, compressor lines, and boiler systems. In contrast, users employ gate valves to manually control fluid flow, enabling complete opening or shutting off of the valve as required. Gate valves excel in applications demanding tight shut-off and isolation, such as water distribution networks and industrial pipelines.

The key difference between the two valve types is their mechanism of operation. Check valves operate automatically based on the flow direction, while gate valves require manual actuation to open and close. This distinction means that check valves are typically simpler in design and require less maintenance, while gate valves offer more granular control over the flow, making them suitable for applications that demand precise flow regulation.

In the realm of fire safety, a well-designed fire water network stands as a critical component for safeguarding lives and property. For businesses and facilities, understanding the intricacies of fire water network design is essential. This comprehensive guide aims to shed light on the key aspects of designing an effective fire water network, ensuring that your premises are well-prepared to combat fire emergencies.

Understanding Fire Water Network Design:

Fire water network design refers to the planning and implementation of systems that supply water for firefighting purposes. This network includes a series of pipes, pumps, and reservoirs that deliver water to fire suppression systems such as sprinklers and hydrants. The goal is to ensure that there is an adequate and reliable water supply to control and extinguish fires effectively.

Key Components of a Fire Water Network:

Water Source: The starting point for any fire water network is a reliable water source. This could be a municipal water supply, a dedicated fire water tank, or natural sources like rivers and lakes. The capacity and reliability of the water source are paramount, ensuring sufficient flow and pressure during emergencies.

Pumping System: Pumps are crucial for maintaining the necessary water pressure throughout the network. Depending on the size of the facility, multiple pumps may be required, including jockey pumps (for maintaining pressure), main fire pumps (for high-pressure supply), and backup pumps (for redundancy).

Piping Network: The network of pipes must be meticulously planned to ensure efficient water distribution. Factors like pipe material, diameter, and layout play significant roles in the overall performance of the fire water system. Pipes must be corrosion-resistant and able to withstand high pressure.

Valves and Controls: These components regulate the flow of water within the network. Control valves, pressure relief valves, and isolation valves must be strategically placed for optimal performance and easy maintenance. Automated controls and monitoring systems can further enhance reliability.

Fire Hydrants and Sprinklers: The endpoints of the fire water network, hydrants, and sprinklers are vital for direct firefighting. Hydrants should be easily accessible, while sprinklers must be adequately distributed to cover all areas effectively.

Backflow Preventers: These devices prevent contamination of the potable water supply by ensuring that water flows in only one direction – from the fire water network to the fire suppression systems.

Design Considerations:

Flow Rate and Pressure: The network must be designed to provide sufficient flow rate and pressure to meet the needs of the firefighting systems. This involves calculating the hydraulic demands based on the size and type of the facility, as well as the potential fire hazards.

Redundancy and Reliability: Incorporating redundancy into the design ensures that the system remains operational even if one component fails. This includes having backup pumps and multiple water sources.

Compliance with Standards: Adhering to national and international fire safety standards, such as NFPA (National Fire Protection Association) guidelines, is critical. These standards provide detailed requirements for the design and installation of fire water networks.

Maintenance Accessibility: The design should facilitate easy access for routine maintenance and inspection. Regular maintenance is essential to ensure the system’s reliability and performance.

Environmental and Site Conditions: The geographic and environmental conditions of the site must be considered. For instance, areas prone to freezing temperatures may require insulated pipes or heating systems to prevent water from freezing.

Implementation Steps:

Site Assessment: Conduct a thorough assessment of the site to understand the specific fire risks and water supply options. This includes evaluating the existing infrastructure and identifying potential challenges.

Design and Engineering: Develop detailed engineering drawings and specifications for the fire water network. This phase involves hydraulic calculations, selecting appropriate materials, and planning the layout.

Installation: Engage experienced contractors to install the system according to the design specifications. Close supervision and quality control are essential to ensure compliance with standards.

Testing and Commissioning: After installation, the system must be rigorously tested to verify its performance. This includes pressure testing, flow testing, and system integration checks.

Training and Maintenance: Provide training for personnel on the operation and maintenance of the fire water network. Establish a regular maintenance schedule to keep the system in optimal condition.

Benefits of a Well-Designed Fire Water Network

A properly designed and maintained fire water network offers numerous benefits:

Enhanced Safety: Protects lives by ensuring a reliable supply of water for firefighting.

Property Protection: Minimizes damage to property and assets in the event of a fire.

Compliance: Meets legal and regulatory requirements, reducing liability risks.

How to Winterize an Irrigation System

With landscaping going dormant for the winter, it's important to properly winterize your irrigation system to prevent damage:

Shut off the water supply at the backflow prevention device or main shut-off valve - This isolates the irrigation lines. 

Release pressure and drain water from the system - Open bleeder valves or blow out sprinkler lines using an air compressor.  

Drain and disconnect sprinkler heads - Remove riser stems to allow water to drain fully from each head.

Blow out a backflow preventer device with compressed air - This clears any residual water from the assembly.

Bring sprinkler control valves indoors if possible to protect from freezing temperatures.

Insulate exposed above-ground pipes most susceptible to freezing - Pipe wrap or insulation protects unburied lines.

Consider blowing out the irrigation controller by running a short cycle to clear pipes indoors.

With all water evacuated, your underground irrigation system won't freeze, shift or crack over the colder months. Reactivating it is as simple as reattaching parts come spring! Proper winterization prevents costly repairs down the road. Click here for information on Plumber jobs in Yate.
