Thank You – Drip System Fixed, Next Challenge: Water Hammer on Grass Valve

Owner thanks for help on drip system (new diaphragm/solenoid fixed 2 GPH emitters). Now needs help with a grass valve that bangs once on shutoff.

Advice

Turn down the flow control on that valve to reduce closing force. If hammer persists, consider a slow‑close valve or water‑hammer arrestor after the backflow preventer.
