discharge valve

 

I want to put something on my sprinkler pump on top, going from output to
the control valves.   If it ever pumps into a "shut off" valve, it could
damage the pump.

Does anyone know of something inexpensive that will serve as a discharge
valve?   Idea being that it will discharge it to the ground until end of
cycle.

 


What you want is a water pressure relief valve that will open if the
pressure goes higher than normal if the sprinkler valves don't open.
It needs to open a a higher pressure that will not occur if the system
is operating normally.   Like this:
