Since my lower drain plug is plugged on my electric water heater, I was told to shut off the electric and cold water supply and open up a hot water faucet, then blow compressed air to the lower valve. After I do that they said to close the hot water faucet turn on the cold water supply and that might loosen up the crud at the bottom of the drain valve.
does that sound good to you ??????

you posted with the same question and were advised NOT to use air.....

throw that one away and cut a new one...."

You are right. I was told by a licensed plumber to do it, that is why I am double checking with the Bob Vila Forum to decide to go forward or not.

Thanks,

i would trust MR.TIEGER'S advice more than any other plumber licensed or not.

Thank for all your help.
