If you would like to stop using your submersible well pump for multiple months, it's always a good idea to drain it and move the submersible well pump to a warmer or temperature-controlled space.
Like our household-use submersible well pump, it may be necessary to provide an additional source of heat to prevent pipes from freezing. Some submersible well pump systems may experience sitting water for long enough to freeze if temperatures fall very low. In these cases, run a small amount of water through your system continuously until temperatures increase again, because it is hard for running water to freeze.
Learning how to prevent the submersible well pump from freezing, it can ensure the submersible well pump do not end up by frozen or cause costly damage.
* Tip: Before starting this project, make sure to shut off the submersible well pump supply lines and disconnect any power going to the pump system to prevent the submersible well pump from running dry after it's been winterized, and from compressed air causing damage to parts of the water system by going where it shouldn't.
Find the drain plug on your submersible well pump and open them to let all the water in the pump drain. Ensure that the most water as possible drains from the submersible well pump. Next, drain the discharge and suction lines. Replace the drain plug before moving on to step 2. Remember that any water left from draining must also be removed to prevent damage to the pump system.
Apply food-grade propylene glycol and fill in pump body, to mix with any remaining water left inside the pump to prevent the system from freezing.
*Important: propylene glycol should never be confused with the automotive antifreeze used in car radiators, which is called ethylene glycol. It is extremely poisonous and can never be used in freshwater applications (especially not in well pumps).
Use an air compressor to blow out the discharge and suction lines in your irrigation, sprinkler, jet, pond, fountain, or any other submersible well pump system. You'll also need an air hose with the proper air fitting connectors.
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, the damage from freezing is NOT a warrantied failure.Wherever you live, you'll be glad you took these steps to enjoy to coming seasons.
When the cold season ends and you're putting everything back together again, make sure you take the proper steps to de-winterize your submersible well pump by following the steps above in reverse. Then, all you'll need to do is re-prime your submersible well pump if it's required.
