We moved into our new 10-year old home almost a year ago. The first few months were fine but about six months ago we suddenly started to hear what we now know as water hammering. We didn't add, change or remove any appliances during this time and the only potential cause I can think of is right around the time we started hearing the water hammering, they installed a sprinkler system down the street in the pond area. As far as I know, my immediate neighbors don't have this problem, just my house. All water outlets in the house cause water hammering, although some, such as the toilet, may be louder than the sink faucet. Our irrigation system may be perhaps one of the loudest.
I knew next to nothing about plumbing before all of this happened but did some extended research online. I've tried turning off the main valve coming into my house, drain the whole system by turning on all faucets and the first few times it helped reduce the severeness of the water hammering but only for the first few minutes.
I called two different plumbers out and neither of them could tell me for sure what the problem is. They both spent about 30 minutes to an hour looking around and confirmed that we indeed have water hammering but neither of them were sure of the cause. The first plumber said we may need hammer arrestors at all water outlets and said he would consult with his master plumber but he never got back with us. The second plumber blamed the fact that there are sections of our pipes in the attic that are 2-4 ft long that aren't tied down. Neither of them were able to explain why the problem started suddenly when the first few months was completely quiet. I highly doubt we only started noticing it a few months after we moved in as it's very loud and noticeable.
Later I did some more research and bought a pressure gauge with a "lazy hand" from HomeDepot. I placed it on the bib right next to the main valve and the black hand stayed around 60 psi but the red lazy hand went up as high as 140 that day. I contacted my MUD and they sent someone out the next day but we were not able to reproduce the spike. When he tested it the red lazy hand only went up as high as 80 and he said it was normal. An hour after he left though, I tested it myself again and the spike went up to 200, the highest on the gauge. I sent them a video of this and so far no responses.
What do you think I should do in this case?
Would installing a pressure regulator help?
Thanks.
