As temperatures start to plummet, ensuring that your backflow preventer is properly winterized is crucial to avoid any damage caused by freezing. Here’s a quick and easy guide from Master Plumber Bryan Graham on how to prepare your backflow preventer for the approaching near-record low temperatures.
Step-by-Step Guide to Winterizing Your Backflow Preventer
Hello everyone! Today, I’m sharing a straightforward process on how to winterize your backflow preventer. This simple task can save you significant costs and hassles during Houston’s cold months.
1. Turn Off the Valves
The first step is to locate and turn off the main valve controlling the backflow preventer. Then, proceed to shut off the connected upper valve. This will ensure no additional water flows into the system while you’re working on it.
2. Drain the System
Your backflow preventer is equipped with small test valves, each featuring a screwdriver slot. Locate these test valves on your device. Carefully open each one by turning them with a screwdriver. Doing this will allow any trapped water to drain out of the system, minimizing the risk of freezing damage.
3. Leave Valves Open
Once you’ve drained the water, leave the test valves open. This step is crucial because any remaining water can expand harmlessly if it freezes. Keeping the valves open protects the internal components of your backflow preventer from pressure buildup caused by freezing water.
Simply follow these steps, and your backflow preventer will be prepared for the winter season. Proper maintenance ensures that your equipment remains in good condition, saving you both time and money in the long run.
