1) Insulate pipes. In Texas homes are often built with little to no attention to if exposed pipes are insulated. You will want to pay attention to crawl spaces, garages and attics. These areas don’t receive heat from the living space of the home and are most susceptible to freezing.
2) Sealing. Sealing leaks of cold air in areas where exposed pipes are located will reduce the chance for a pipe burst.
3) Disconnect the garden hose and cover with an outside faucet cover.
4) Set thermostat to no lower than 55 F. Most insurance policies exclude coverage for a bursting pipe when heat is not maintained at a premise.
5) If you leave town make sure to have a neighbor or friend check on your home and/or shut off your water supply.
6) Dripping. Opening a faucet will provide relief from the excessive pressure that builds between the faucet and the ice blockage when freezing occurs. Even very little flow will allow the pressure to release.
If you still experience a water claim, make sure to turn off the water main, take steps to prevent further damage, and contact your insurance company to file a claim.
