I have a hayward pump that doesn't want to stay primed on the pool suction side. It is plumbed with a jandy valve to select between spa suction and pool suction.

A hose is attached to the fire hydrant, then the valve is opened to provide a powerful flow of water, on the order of 350 kPa (50 lbf/in) (this pressure varies according to region and depends on vario

Structural ceramics are used on the gate valve and seat to resist wear, corrosion, high temperatures and thermal shock.
