Hi! This site looks awesome! I hope I can get a few questions answered and maybe provide some help in some other areas since plumbing is not my forte. I have a banging water heater and I've read all about the sediment that causes it. I want to make sure that's what it is before I invest in another heater. It's 10 years old and I probably drain it about every year and a half on average. It started banging one morning a few days ago but only when one of our 3 toilets are flushed and it bangs while the toilet is filling. I tried draining the heater. That didn't work so I tried flushing the heater (drain open and supply open). The banging was constant while water was supplying the heater. So I have banging when any of the 3 toilets are filling or when I'm flushing the water heater and not when any other faucets or appliances are being used. I'm confused at why the banging is only occurring from toilets filling and not with anything else. Shouldn't it be banging when a faucet or appliance is using hot water?
