Well Foot Valves: this article describes the foot valve used on well piping for water well Pumps & Water Wells: we explain what a foot valve is, how they work, why they are used, and how to diagnose troubles with this special in-well check valve found at the bottom of well piping in some wells. We provide advice about loss of well pump prime due to bad foot valves and what to do when things go wrong with the check valve.

Frequently Asked Questions (FAQs) about locating, using, diagnosing, repairing, or replacing well pump check valves and foot valves and loss of well pump prime or other well piping leaks and pressure losses
Question: do jet pumps come with a built in check valve or do I need a foot valve or both?
I have model pkg 1-54AP 2" single pipe jet kit for a sta-rite sld-l 3/4hp jet pump. Does the jet package come with a built-in check valve and if it does, do I need a foot valve? Thanks! - David
David take a look at the page top photo - if your kit didn't include something that looks like that, you don't yet have a foot valve.
Question: how do I protect the well water piping in the well from freezing?
When draining the water from a dwelling that is allowed to freeze, how does the water supply from the submersible pump, supplied with foot valve, drain so the at or above grade pipes don't freeze and break? - Nate
Reply: well piping and pitless adapter should be below the frost line

Question: shallow well pump keeps losing prime
I have a shallow well that the pump will lose prime. It will prime up to pressure at currently 45 psi, once demand increases the pressure will go gradually down and suddenly drop 10 - 12 psi thus losing prime at 10 - 15 psi to never recover until I prime again. Attempting to prime, there's alot of air bubbles. I just replaced the check valve and bladder tank. I times i can take a long hot shower with no problem or if I just flush the toilet it will lose prime. Can anything be drawn from this?
Bob: on intermittent loss of well prime, you'll need to determine if the leak is in well piping between house and well bottom ( perhaps a leaky well line or bad foot valve) OR a leak at the water pressure tank or an above ground well pump. Shut off all water to the house and watch pressure in the system. If it drops then the leak is outside.
