Wells, pump houses and septic systems in freezes and storms

Rural Newberry County runs on private wells. When a well line or pressure switch freezes, the whole house is out of water, and a split pipe in the pump house can empty the tank and wear out the pump.

What freezes

  • The pipe from the wellhead to the pressure tank, where it runs above ground.
  • The pressure switch and the small tube that feeds it. If that freezes, the pump may not turn on, or may not turn off.
  • The pressure tank piping, and any filter or softener in an unheated pump house.

Before winter

  • Insulate the pump house walls and door, and seal the gaps.
  • Insulate all exposed piping and the pressure switch tube.
  • Use a heat lamp or heater in the pump house only if it is a listed product installed safely, on a thermostat, away from anything flammable. Follow the CPSC's rules for any heat tape on well lines. Heat cable safety.
  • Know which breaker runs the pump.

When the power goes out

Without electricity the well pump stops, and so does any heat in the pump house. You will have only the water left in the pressure tank. Store drinking water before a winter storm. Plumbing in a power outage.

If the well line freezes

  1. Turn off the pump breaker so the pump does not run against a blocked line.
  2. Warm the exposed pipe and pressure switch gently with a hair dryer, heat lamp or heating pad. No open flame.
  3. Restore power and watch for leaks. If water sprays, or the pump runs without stopping, shut it off and call a well or pump contractor.

Testing and permits

SC DES (the SC Department of Environmental Services) permits new private wells and offers low-cost well water testing through its regional offices. It does not regulate the water quality of private wells, so testing is up to the owner. Test after any flood that reached the wellhead, or if the water changes taste, color or smell. A new well needs a notice of intent filed with SC DES before it is drilled.

Septic systems

  • Septic lines rarely freeze here, but a system that is barely used, such as at a vacation house, can freeze where pipes are shallow.
  • After heavy rain or flooding, the EPA advises against pumping the tank while the drain field is saturated, and suggests cutting back on water use.

Frequently asked questions

Why do I have no water from my well on a cold morning?

The pipe between the well and the pressure tank, or the pressure switch tube, has probably frozen. Turn off the pump breaker, warm the exposed parts gently, then restore power.
