Every year we get repair calls because the freeze damaged a backflow device. Many times you don’t know it because the freeze damage doesn’t show itself until it thaws. Then, water goes everywhere!
Here in central Texas, an ounce of prevention is definitely worth a pound of cure.
If you have a Double-Check Assembly type of backflow device, you’re normally okay because most DCAs are buried. But, if you have one of the other types of backflow devices, you’re vulnerable to freeze damage because they cannot be buried. The two main types that burst when it freezes are the Reduced Pressure Zone (RP or RPZ) and the Pressure Vacuum Breakers (PVB).
What to Do if Your Backflow Preventer Freezes
If you have an isolation valve for your sprinkler system, use it to turn the water off. If not, you’ll have to turn off your water meter and call us pronto.
There’s more here than meets the eye: Your backflow prevention device must be repaired or replaced. You probably knew that. But, before a licensed backflow specialist can bring your system back to working order, you must bring your sprinkler system up to code. That may not be a big deal, but if your sprinkler system is way out of code, it can be an additional expense.
We can tell you what you need. We will give you an up-front price to get everything Kosher and all that won’t cost you a dime. So, I hope you’ll call. Our number is 254.829.3800.
