Ask a Question
Does this pump not have a check valve? I've got this installed and the pump runs and fills the pressure tank up, but as soon as it cuts off, all the water flows back through it. I'm not sure if it just doesn't have a check valve, or if mine is not functioning properly.

Well jet pumps do not have a check valve. Instead, a foot valve (installed at the very end of the suction pipe in the well) acts as a check valve and prevents the water from flowing back into the well.
