What causes a water pump not to prime?
Leaks on the pump’s intake line as well as around the shaft seal of the pump housing itself can cause your pump to lose its prime. Obstruction-One possible reason your pump may be losing its prime is an obstruction or blockage in a line. Debris blocking the suction strainer or foot valve is the most common cause.
What makes a pump self priming?
What is Self-Priming? If a pump is located beneath the level of the liquid to be pumped, gravity and air pressure ensure that it is constantly filled with the liquid and there can be no ingress of air into the pump or suction line. Such a pump is considered to be self-priming.
What should I do if my water pump is losing its prime?
Valves- Most pumps are equipped with foot valves to keep water in the intake line and casing when the pump is not running. If your foot valve is leaking your pump may lose its prime between starts. Replacing a faulty valve may solve the problem.
What causes a pool pump to not prime?
Most priming problems involve leaks in the suction side of the pump (between the pump and the pool) or clogged baskets. If you have a leak on the pressure side (after the pump), it does not affect prime.

Why does my jet well pump keep running?
“Priming the pump” means that the intake pipe on a jet system must always be filled with water (primed) in order to generate enough suction to pull water out of the well and into the household water line. If your well pump loses prime, then it will run constantly. Generally, jet pumps lose prime when there’s a leak in the suction line.
