In response to Re: Unable to drain hot water tank?
Don:--Go to your nearest Plumbing Supply or Home Center, and get...
A 3/4" galvanized nipple X 3" long.
A 3/4" FIP full flow Ball Valve
A 3/4" MIP X Male hose thread adapter.
Shut the water and power off to the heater...
Remove the useless drain valve that came with the heater. Screw in the pre assembled nipple.valve
and hose adapter. Attatch a hose to the new drain
arrangement. Turn the water back the new valve. Remember that if your heater is in the won't drain up the stairs and outside by gravity, you will need to drain it by gravity in the basement. Once the water is out of the tank, remove the lower element, and suck all the mineral debris out with a wet/dry vacuum.
Replace the elements with low watt density elements or long life elements and that crud will not come back...Lots of luck...Bud
