In August or September,the fire department came around and tested\flushed the fire hydrant on the corner ( I'm 3 houses away from it). Any hoo, shortly after, the screen in my bathroom faucet became plugged, unscrewed it and cleaned it out and its worked fine, however the water heater started popping and has gradually gotten worse (sediment or calcium build up). I have Googled the problem and it suggested to drain the water heater and pour CLR into it and then flush it out. My question is, has anyone flushed out their water heater and had success doing it? Thanks.
