Need help with water service noise / banging....
So my old setup was just pipe, an old valve, and iron pipe into the water heater, 40 gal. No checks, xtank or anything. Never a problem.
New system is all copper, tankless, x tank, PRV, and filter on service with gauges before & after PRV. At night, I noticed constant banging throughout the house. Few days later, I realize it's all day, and it's the water service. Gauges show pressure coming in at 78, house set to 65. Incoming pressure varies a few lbs, then dropped to 65 or less, and when it recharged it banged my pipes hard. This happened over and over. So I call the City. We watch the meter as it "breaths" in & out against my x tank. No check on the meter or yolk.
So I install a swing check first thing in line inside my house. Now, I can hear the banging of the service drop and recharge, but my gauges stay firm. Much, much quieter (faint) but rhythmic and constant. Thump, thump, thumpthumpthump, thump.
My concern is how this affects my 100+ year old service line. Now I see more & more rust in the house filter.
Can I demand a check at the meter??
Working on steam and hot-water systems isn't rocket science....it's actually much harder.
