January 10, 2024 Amanda Cox Comments Off

When the temperature drops pool owners shouldn’t worry if water freezes across your pool’s surface. Your main concern should be with your pool pipes and equipment. If your pool equipment isn’t winterized, water can freeze inside of your pump, filter or heater damaging these components so it’s important to keep water flowing through your pool’s system the entire time the temperature is freezing.

There are things you can do to prevent costly repairs and replacement:

Keep your system running 24/7

DON’T let your water level drop.

DO NOT cover your pool heater with insulation or a blanket.

If the power goes out and your pool system stops running:

Prepare your backflow device:

Freezing temperatures don’t happen too often in Houston, but when they do, it’s important to prepare! With the arctic blast scheduled to hit Houston on Thursday, taking the time to prepare your home and yard for the freeze could save you hundreds of dollars on burst pipes.

Following the below steps will help depressurize your system and prepare it for the freeze. There are so many variables that can cause one residents irrigation to freeze and the next door neighbors not to freeze, the biggest being is your backflow preventer being exposed to the north.

Follow the steps below to remove water and winterize your backflow device:

STEP 1: Turn off the shutoff valve

On most residential backflow devices, there are two shut-off valves. These are typically covered in blue rubber and are located before and after the actual backflow device.

STEP 2: Release the water pressure

Now that you have shut off the water valve, you must release the water that is in the device so that it doesn’t expand when it freezes and crack the device. With a flat head screwdriver, loosen the two bleeder valves (#3 and #4 as illustrated). The bleeder valves are usually located just under the plastic top of the backflow. Sometimes, they have rubber inserts you have to remove before you can see the flathead screw. When opening these, be aware that the water will spew out for a few seconds and your hands will get wet. NOTE: If the water doesn’t stop spitting out after a couple minutes, you haven’t fully turned off the water in step 1.

STEP 3: Leave the smaller bleeder valves open

This will allow the water to expand and freeze without being hindered and causing damage.

STEP 4: Insulate your backflow

At almost all home improvements stores, they carry backflow preventer insulation materials. Amazon and other stores also carry insulated bags that can be slipped over your backflow and secured with velcro.
