hot water heater question - since we're all plumbers here ;-)
So, I'm sure this is a general enough question for those that know:
Last night I heard knocking coming from my hot water heater. I took the day off of work today to fix the darned thing, and I hope I spent my day off wisely by flushing out the hot water heater correctly.
I turned off the gas to the hot water heater. Attached a garden house to the spout on the bottom of the unit. Turned off the cold water supply. This is where my question comes in at... I read that you need to open the pressure relief valve at the top of the water heater, but when I did, hot water just pours out. I filled bucket after bucket of hot water (which was dirty, rusty, and had white stuff at first), till I decided to just close the valve, and open the valve where the hose is attached to let the bottom drain out. I let it drain till the water was clear.
I hope I didn't just waste a PTO day by not doing the right thing
I guess I'll find out later if it's still knocking...
