I have a dry system fed by a booster pump that takes suction off of a pumped
well system
feeding a plant.
The darn dry pipe valve keeps tripping and my thoughts are that when the plant
well pumps
shut off it's sending a water hammer into the fire pump suction line.
I believe the water hammer is causing the pump sensing line to act erratic
causing the pump to run thus
tripping the dry pipe valve.
Anyone have any suggestions about how to fix my problem, a expansion tank or
water hammer arrestor
comes to mind.
Thanks,
Mike Hairfield
