Reasons to Winterize Your Sprinkler System

Reasons to Winterize Your Sprinkler System

Why do you need to winterize your sprinkler system? Damage prevention is the easiest answer. Built-in sprinkler systems, though robust, can’t handle the frigid temperatures that winter brings.

Frozen water inside pipes makes them vulnerable. Excessive pressure formed due to expanding ice leads to cracked pipes and broken sprinkler heads. Sprinkler repairs are costly, with the price tag often going into the hundreds or thousands of dollars. As a homeowner, that’s an expense you don’t need.

Protecting your investment is another critical reason for winterization. You’ve put time, effort, and resources to install a sprinkler system that keeps your yard and garden looking lush. You don’t want to lose that investment to avoidable damage.

Lastly, let’s talk about saving time and avoiding headaches. The time you spend now to shut down your system properly will be a lot less than the time spent fixing it in spring. You’re also casting aside the stress of potential malfunctions that may interrupt your spring outdoor plans.

With all these advantages, it’s clear that winterizing your sprinkler system isn’t just a chore—it’s a wise choice.

Here’s a quick look at the typical cost of sprinkler repairs, for your understanding:

Repair typeCost range (USD)
Fix broken pipe100 – 200
Replace sprinkler head50 – 100
Total system repair500 – 1500

Remember, these are just average costs – every repair is unique and charges may shoot up based on the extent of damage and the complexity of the fix. Better to be safe than sorry right? In the following section, we’ll walk you through the steps to winterize your system effectively, helpingyou shield it from harsh winter damage.

Tools Needed for Shutting Down the System

Tools Needed for Shutting Down the System

Knowing what tools will come in handy when turning off a sprinkler system for winter is essential. Here’s a clear breakdown of the essential items you’ll need.

An Air Compressor: One of the key tools for winterizing your sprinkler system. It’s used to blow out residual water lingering in the pipes, reducing the chances of freezing and potential damage. You’ll require an air compressor that can deliver adequate cubic feet per minute (CFM) output for your system size.

Insulated Tape or Foam Pipe Insulation: Protect your backflow preventer and exposed pipes with these products. These will help keep them insulated from the harsh winter elements and reduce the risk of freezing.

When selecting foam pipe insulation or insulated tape, you’ll want to make sure it’s weather-resistant and able to handle fluctuating temperatures and moisture levels.

Sprinkler System Manual: Don’t overlook the usefulness of your sprinkler system’s manual. This manual contains specific instructions and diagrams about your system, which can be invaluable during the winterization process.

Flathead Screwdriver and Adjustable Wrench: Basic tools such as a flathead screwdriver and an adjustable wrench can be useful for adjusting sprinkler heads or accessing the system’s interior parts. You want to make sure you’re equipped to handle any manual adjustments that may be necessary in the process.

Equip yourself properly and winterizing your sprinkler system will become a straightforward task. Planning ahead and having the right tools on hand can make all the difference. The investment into these tools can save you from the hefty costs of repairing a damaged system after winter.

Step 1: Turning off the Water Supply

Now that you’ve got your necessary tools laid out, let’s get into the thick of it. The first vital step in winterizing your sprinkler system is turning off the water supply. This step is crucial for protecting the sprinkler system from freezing and potential damage.

To locate the main water valve, you’re likely going to find it mounted on a basement or external wall, or sometimes buried in a box in the ground. If you’re having trouble locating it, refer back to your sprinkler system manual.

You might also find it useful to know that there are two types of main water valves — gate valves and ball valves. For gate valves, you’ll need to turn the valve several times counterclockwise, while ball valves require just a 90 degree turn counterclockwise.

Upon turning off the water supply, it’s essential to drain the remaining water from the system. To drain the residual water, locate the drain valve (it’s often close to the main water valve). Open this valve and allow the water to drain out.

Remember as an important measure of safety, never stand directly over the drain valve while opening it. The force of the water draining out can cause injury. In addition, water sprayed up from the valve may damage nearby structures or surfaces.

Remember, turning off the water supply forms the first imperative step towards safeguarding your sprinkler system. Make sure it’s done right. Don’t rush this step and don’t be tempted to skip it.

We’ll move on to releasing water pressure from the system in our next step. So keep your tools handy and stay tuned.

Step 2: Draining the System

After successfully turning off your home’s main water supply, it’s time to move onto the next phase: draining the sprinkler system. Proper drainage is key in the winterization process. It helps prevent freeze-ups that could cause significant damage to your sprinkler system.

There are typically three types of draining methods you can use:

  1. Manual draining method
  2. Automatic draining method
  3. Blow-out method

The Manual Draining Method

If your system’s pipes are designed above ground or inclined, you’ll likely use the manual draining method. To drain the water manually, first locate the drain valve—they’re typically located at the lower parts of your sprinkler system—and open it up. Here, it’s essential to not stand directly over the drain valve while doing so, for safety reasons.

The Automatic Draining Method

In contrast, if your sprinkler system has automatic drain valves built in, you have an opportunity to let your system do the work for you as soon as water pressure drops below around 10 psi.

The Blow-Out Method

The third and riskiest method of draining your system is the blow-out method. Here, you’ll use an air compressor to blow residual water out of your system. It’s crucial to wear safety glasses when using this method and don’t exceed the recommended PSI for your specific sprinkler system to avoid unnecessary blasts or incidences.

Take note that these methods don’t necessarily assure the absence of all water in your system – a small volume might still be present. As such, it’s advisable to consult with a professional or your sprinkler system manufacturer to make sure the chosen draining method is appropriate.

Step 3: Insulating Any Exposed Pipes

Step 3: Insulating Any Exposed Pipes

After you’ve carefully drained your sprinkler system, step three in winterizing requires insulating any exposed pipes.

Exposed pipes are your sprinkler system’s weakest links when it comes to freezing weather. Failure to insulate exposed pipes and valves may result in severe damage. This is especially true if you live in regions where temperatures plunge below freezing during the winter.

To insulate exposed pipes, visit your local hardware store to find pipe insulation supplies. Insulating foam tubes are a popular choice, as these are quite efficient at fending off freezing temperatures. Remember to correctly measure the diameter of your pipes before you head to the store. This ensures the foam tubes fit snugly around your pipes.

Here’s a simple breakdown of the process:

  1. Measure Pipes: Use a tape measure to properly assess the diameter of your pipes.
  2. Acquire Insulation Supply: Based on your measurements, purchase the appropriate insulation.
  3. Apply Insulation: Fit the insulating foam tubes around your pipes. You should cover every inch and secure with waterproof tape, providing a thorough shield against cold weather.

You might be wondering, “What if my pipes are situated underground?” If that’s the case, don’t sweat it! Usually, underground pipes don’t require insulation, thanks to the ground providing natural insulation against freezing temperatures.

What’s more important is to pay attention to above-ground backflow preventers. Backflow preventers, like your pipes, can be a casualty of freezing weather if left unprotected. They should be insulated much like your pipes, by using insulating foam tubes secured with waterproof tape.

Winterizing a sprinkler system is a process. You need patience and preparation but investing this time and care invariably pays off in terms of protecting your irrigation system against harsh winter conditions. After insulating exposed pipes, you’re one step closer to a completely winterized sprinkler system.

Conclusion

You’ve now learned the key steps in winterizing your sprinkler system. The importance of insulating exposed pipes can’t be overstated, particularly in colder climates. By taking the time to measure your pipes and secure the insulation with waterproof tape, you’re taking a crucial step in safeguarding your irrigation system against the harsh winter. Remember, underground pipes may not need insulation, but don’t forget about your above-ground backflow preventers. They need the same care and attention. Winterizing your sprinkler system might require some patience, but the long-term benefits make it a worthwhile endeavor. You’re not just protecting your system – you’re ensuring its longevity. So, as the cold season approaches, you’re now equipped with the knowledge to keep your sprinkler system safe and sound.
