A pressure reducer cut into the house supply plumbing, just after the point where the sprinkler supply tees off, will provide a stopping point for the banging. Upstream of the reducer, you still get water hammer - downstream of the reducer, you get little or no hammer.

There are some products out there that you can use to stop "water hammer". One of these is called "Water Hammer Arrestors". This would just be installed in the line, but depending on the severity of the water hammer, you might have to have multiples or a very large one. Another avenue would be to switch to a higher quality valve and one that may offer pressure regulation. Sometimes this can eliminate water hammer. One of the tricks that golf courses used war a series of fluid resisters in the solenoid chamber. This would slow the "on" and "off" speed of the valve and usually eliminating the water hammer. Most of this will not be compatible with your brand of valves, but it is a start to get you in the right direction. Best of luck!

Valve shutoff causes Hydrolock

I use an Orbit 6 station outside timer and watermaster water valves. My problem is when the valves shut off they cause the pipes in my house to "bang". Is there a way to slow the shutoff solenoids down to emiminate the "bang".

Any help is appreciated.
