How to Winterize Your Pump

By  | Water Pump Product Expert

Winterizing your pump and water lines are crucial steps in preserving your property before sub-zero temperatures arrive.


When water freezes, it expands by about 9%, while other materials, like metal found in water pumps, tend to contract getting smaller as temperatures drop. This combination can lead to water lines that burst and a cracked cast iron pump.



So, follow these steps and don't let old man winter destroy your water pump!


Winterizing Takeaways:

  1. Remove the motor or anchor the pump to the deepest level for submersible pumps, fountains, and aerators.
  2. Drain the pump body completely in above ground pumps such as: jet pumps, pool pumps, and irrigation systems.
  3. Use food-grade propylene glycol - Never use ethylene glycol used in automotive radiators.
  4. If the pump or line cannot be drained completely maintain a small stream of running water.
  5. Use compressed air to blow out discharge and suction lines.

An ounce of prevention is worth a pound of cure - Benjamin Franklin Even if you live in a warmer climate, all it takes is one good cold-snap to break your pump and cause catastrophic damage to your property.


What's more, is damage from freezing is NOT a warrantied failure, so you'll be out a pump and left to clean up the mess yourself. Wherever you live, you'll be glad you took these steps to enjoy to coming seasons.
