I would like to install after the pump an automatic pressure relief valve; up to 50 psig.
Ideal would probably be an add on to the water pipe, or mounted on the sand filter where a manual air vent is.
I have a nightmare scenario:
Installation has a flap water flow valve that has inside relays under full line voltage. If the seal is blown - water + electricity will do ugly things.
If the line to the pool is obstructed (e.g. closed valves) the pump may create pressure that may blow a lot -- water seals in the electric valve or explode something else.
The least damage is that the flow valve needs replacement - the most is somebody gets killed - as unfortunately most dealers install pumps and equipment without GFI circuit breakers.
Any suggestions what automatic pressure relief valve to buy that would be relative easy to install.
