We have a 2 month old house with a gas water heater that makes popping noises each time the hot water is turned on.
I have seen where hard water is an issue. We do have a water softner as well.
I have also seen where calcium buildup is a problem but this thing is only 2 months old.
There is also a small hot water recirculating pump since the house is pretty big but the noise seems to be coming out of the top of the hot water tank.
Ideas anyone?
Thanks
