I posted a quick question a couple weeks back, this is a follow up.
I'm trying to drain my water heater, Sears PowerMiser 9, and I can't get
water to come out when its supposed to.
Here is what I have done.
Shut off cold water supply, opened all hot water faucets, connected garden
hose to drain spout, opened drain spout. Nothing, no water flow at all.
Did all the above, turned on cold water supply. Nice clear hot water poured
out of garden hose at a reduced pressure.
Removed garden hose, obvious vacuum breaking sound, opened up faucet.
Nothing, water heater gurgled for a couple of seconds then stopped.
Am I gonna have to totally disconnect the water heater from the system in
order to do the bi-annual draining that the manufacturer suggests? I just
don't want to do that, considering all the water that's gonna dump all over
the place when that happens.
What about opening the pressure release valve?
