Water – Pumping water using a small electric pump, does it need to be potable


I am doing a little DIY project where I need to pump 4-5 gallons of water that is less than 100'. I need the pump to be able to run dry as it starts to pull the water, then it would pump the water.

Does this need to be a potable pump? Non-potable pumps are much cheaper and I will only be running the pump like twice a month for 20 minutes at a time.

non-potable example, a little pond pump from Home Depot.

With it being hard plastic, I just can't see how it could have an issue. The water does need to be drinkable..

If you will be drinking the water, you need a potable water pump. "Potable" means "safe to drink." No matter what, if needs to be able to start dry, you need a "self-priming" pump.
