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