Texas may not see long, frozen winters—but one hard freeze is all it takes to burst pipes, crack pressure tanks, and damage your pump. Unlike northern states where winterization is a months-long process, Texas well owners can protect their systems in a single afternoon. The key is focusing on the vulnerable points that are most likely to freeze when temperatures unexpectedly drop below 32 degrees.
Insulate Exposed Pipes and Fixtures
Walk your property and identify any pipes, valves, or fittings that are above ground or in unheated spaces. This includes the pipe running from your well to the pressure tank, any outdoor spigots, and pipes in pump houses or crawl spaces. Wrap these with foam pipe insulation sleeves, which cost just a few dollars at any hardware store. For areas that have frozen in the past, add heat tape underneath the insulation. Pay special attention to PVC pipes—they become brittle when cold and crack more easily than metal pipes.
Protect Your Pressure Tank and Switch
If your pressure tank is located in an unheated building or above ground, it needs protection. A waterlogged pressure tank is especially vulnerable because water fills the entire tank rather than just the lower portion. Insulate the tank with a blanket or insulating wrap, and ensure the pressure switch cover is securely closed to keep moisture and insects out. A frozen pressure switch can prevent your pump from starting when you need it most.
Drain Outdoor Lines and Hoses
Disconnect and drain all garden hoses. A hose left attached to an outdoor spigot can trap water in the faucet, causing the pipe to freeze and burst inside your wall or foundation. Drain any above-ground sprinkler lines or irrigation systems. If you have a shut-off valve for outdoor water, turn it off and open the outdoor spigots to drain remaining water.
