Re: pipes banging
Likewise, I've never noticed any product marketed as a "whole-house water hammer arrestor." I would think an expansion tank like that on your water heater would do the job when placed on the main line.
I'm wondering if it's possibly an expansion/contraction issue. A while after hot water is used, the pipe cools off and contracts. While it's contracting, it's bound up in the holes it passes through in the studs or joists. Eventually, the tension on the pipes overcomes the binding, and it suddenly releases with a loud BANG!. Kind of like the San Andreas Fault, if you will.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
