Since moving into my house in January 2018 we have been plagued by this occasional banging noise in the pipes when water is shut off.
Looking online I see that it is probably water hammer or resonance, but any examples I have heard don't exactly sound the same.
What we get is either a rapid fire (maybe 4-6 per second) bangs that quickly diminish OR a repetitive slower (1-2 per second) bang that can last up to a minute (that's the longest I've let it go before turning on another faucet)
Couple key points:
This banging can happen from seemingly any faucet in the house
Most of the time I can get it to stop by turning on any faucet and VERY slowly turning it off, sometimes I have to do this multiple times in order to get it to stop
It seems to happen primarily from faucets, I've heard it from a toilet once or twice, but I've never heard it from a shower/tub or spigot
Happens on both hot and cold side, though seems primarily cold water (probably 85% cold and 15% hot)
I cannot see any hammer arresters or anything, though there is a gauge right next to the pump that doesn't really show anything when the banging happens as far as I can tell.
About the setup:
I have a well (250ft) with a 3/4HP pump that I just had to replace last year (this problem predates the replacement)
Original house built in 1986 (2 bed 2 bath)
Addition sometime in the mid to late 90s added another bath on the second floor
Garage addition sometime in the early 2000's added yet another bath upstairs.
The well pressure tank is just inside right before the gauge
The gauge has some sort of spigot attached to it (see attached pictures)
From the pump it goes:
Pump-->Tank-->Gauge-->Iron removal system --> rest of the house
One thing I found weird is that leading up to the Iron removal system it's a 1" pipe, then goes through the tank with 3/4" then back to 1" after the tank (though I'm assuming that's only because the Iron system was installed after).
Would adding a hammer arrester possibly fix the issue?
Anything else I can check?
