How To Keep Above-Ground Water Systems from Freezing

Connect your supply line to the water source and protect it

• If possible, dig a trench five to six inches wide and as deep as the soil will allow from your water source to the area under your house where you plan to route the supply line. (Some areas have enough soil to bury the line, but not enough to protect it from freezing.) Where you route water into your home depends on your floor plan and the location of your water pressure tank. I brought in my supply line into my laundry room because that’s where my pressure tank is, and where my interior water pipes branch from.
• Lay lengths of 4-in.-dia. ABS pipe end to end in the bottom of the trench, or on the ground/bedrock if you can’t dig.
• Join the ABS ends together with ABS cement. If it’s a drilled well, extend the pipe to the well casing. If it’s a cistern, go to the main outlet. And if it’s a lake, right to the water.
• Thread a one-inch water supply pipe through the ABS pipe and connect it to your water source with a PEX expansion ring and ProPEX expander tool. Be sure to use PEX pipe because it won’t burst if the system ever fails and the water freezes.
