Water hammer

I just had someone call me and say their neighbor just had a new irrigation system installed. Since that time the caller has been hearing his pipes rattle in his 10 yr old house in association with the neighbor's new system running. He was asking me if he should get a lawyer and who should be held accountable. Glad I'm not involved! Anyway, it raised some questions:

How does this happen? Is it just poor system design with excessive pressures? Would a check valve at the cross connection reslove this? Any input appreciated.

A check valve and a pressure tank might help - check keeps the house pressure inside, and the pressure tank is a "shock absorber" - always use the two in conjunction, or else bad things can happen

Thanks. And this combination would go between cross connection and backflow preventer, right?

Back up a moment. Your question is about the home next door to a new sprinkler system. The sprinkler system owner can't do anything beyond closing down the flow control on zone/master valve(s)

If it really matters, there will be more information coming. Right now, not enough.

Who gets to drop the bomb that the system was over zoned?

One small advantage to the basement meters - the effects of poor design don't extend to the neighbors

Check valve will help... is there a pressure regulator to the house?

Sounds like you need to be working on the neighbors system.

prob poor design and too much pressure. my vote goes for the tank and check as well. not much you can do other than that i believe without serious costs, and at the neighbors to boot
