With the weather getting cooler, the first fall frost won’t be far behind. Your lawn is slowing its growth and your pool is likely doing nothing but collecting leaves. Winterizing your pool and sprinkler system should be at the top of your to-do list.
1. Drain Irrigation Lines
Shutting off the water to your sprinkler system is the first step. Your main shut-off valve should be located in your basement or crawlspace. There are three different methods for draining the lines:
- Manual drain
- Auto drain
2. Blowing Out is Best
To insure that you have removed all the water from your pipes, blowing out the lines is the most effective. Determine what type of lines you have – black polyethylene pipes or white PVC piping. The type line you have will determine how much pressure you can use to remove the water.
3. Too Much Pressure = Damage
Polyethylene pipes can withstand up to 50 PSI (pounds per square inch) while PVC can take up to 80 PSI. You will need to check your air compressor’s rating before you start. Too much pressure in your lines and you can seriously damage your pipes and valves.
4. Watch for Flying Debris
Connect the air compressor to the mainline just after the backflow device. Always keep at least one control valve open to avoid damaging the system. Start with the furthest sprinkler location and blow-out each line. Be careful of flying debris coming out of your lines. Wear safety goggles and keep clear of the valve during a blowout.
5. Insulate Exposed Equipment
Besides blowing out the lines, make sure you protect any equipment that may be exposed to the elements. The backflow prevention device is usually located outside near the foundation. The “bonnet” and “poppet assembly” inside this device can freeze and burst, causing costly damage. Wrap it with insulation and cover with a plastic bag. Duct tape the bag shut to keep out moisture.
6. Remember the Controller
Don’t forget to address your automated controller. Put it into “rain” mode, which will allow the timer to continue to run (saving your programmed settings) but shut off all the valves. If your controller connects to a pump, you may want to disconnect the power to it. You will lose your settings but the pump motor will not burn out from continuous use.
7. Preparing Your Pool for Winter
Winterizing your pool is a definite must-do. Clean all the debris from around and out of the pool. It’s important to leave water in your pool. Without the weight of the water, frozen ground can expand and cause a pool to rise up, cracking it. Lower the water level just below the mouth of your skimmer.
8. Cover Pool for Safety
Make sure the water chemistry is balanced to protect against staining and etching. Add a winterizing chemical kit to the water to keep it clear of algae. Cover the pool to keep out debris, inspecting the cover for any tears. To keep water off of the cover (and children safe), you may want to invest in an automated pump. Store all of your pool equipment (ladders and slides) to protect them from harmful weather damage.
9. Winterization Plugs Keep Water Out
As with your irrigation system, you need to drain all plumbing lines associated with your pool. After blowing the water out of the pipes, seal the line on the pool end to keep water from getting back into it. Many pools come with plugs specifically for winterization.
10. Winterize Filter, Too
Don’t forget about your filter. There is a plug at the bottom that will allow water to drain out. Open the air relief valve if you have one. Put the multiport valve in the “closed” position and remove the pressure gauge. Cover any exposed equipment with insulation and a plastic bag to keep moisture out.
Winterizing your pool and irrigation system keeps you from experiencing the headaches of ruptured water pipes and costly repairs. While ice sculptures created by a burst pipe might appear beautiful, your wallet will not think it is so spectacular. Save your money for more important things like suntan lotion and a new pair of shades.
