The OP said he is getting water out of all of his faucets, so the hot water tank is obviously filling. The relief valve may be plugged?

If there is water coming out under pressure from the HOT water faucet, yet it is not hot AND there is no water or air coming out of the hot water heater relief valve when it is opened, then the bypass valve has to be the problem (clogged or broken).

Or there is a multiple malfunction; which is possible but unlikely.

Don't think OP has turned the water heater on yet, he is wanting to make sure it is full before starting it.

I thought about this too. If the outside or inside shower faucets were both open and the shower handle was shut off; cold water would enter the hot water pipes allowing both faucets to show water pressure without having the tank filled. (valve in the correct non-bypass position)

If the pressure relief valve was plugged, as the only malfunction, hot water would still flow out the faucets; just not out the relief valve.

So, no hot water; cold water under pressure at the hot water tap; and no water/air at the relief valve is quite the conundrum.

I would be cracking the "B" nut just prior to the bypass valve to make sure there was water there. Replacing the valve may do the trick. I think a clogged bypass valve might be the problem.

Bottom line, either the bypass valve is clogged/defective or the relief valve is plugged. Fastest, easiest and least messy thing to do is remove relief valve.

Evidently we lost the OP witchcraft, he evidently went to work on it or got tired of reading all the posts.

Water heater, relief valve

Thanks guys for all the great info. I'm convinced there is only one bypass valve so I'll look at the relief valve then replace the bypass if necessary. Had water to all faucets and showers were not the issue. Couldn't do it without all your help.

Thanks to all of you. It was a stripped valve (and there is only one) that somehow got broken. Replaced it and everything works fine. Thanks again.
