No hot water

So I'm going crazy!! the hot water tank works, I removed the bypass valve because I was having low water pressure on the hot side. I have great pressure, but no hot water at the faucet
As I said, there is hot water in the tank as I can feel the pipe coming from the tank is hot, just nothing at any of the faucets. This has to be a simple fix, but it has me stumped
Thanks

Ken

Me, I would inspect the bypass valve for restrictions, if it looks ok then reinstall it and work from there. Better low hot warer pressure than none.

I totally removed the valve because of the almost no water pressure and no hot water at that time either....so, good pressure, just no hot water

Twice you have said "Valve" not "Valves" May I assume you have a single valve bypass system?

How, with that system how do you think they prevent Pink Stuff from entering the tank when you winterize?

Answer: A check valve on the water heater outlet..

Some units even have one on the inlet (Don't ask me why I don't know).

The one on the outlet, over time, gets "Crudded up" with lime and other minteral deposits and it sticks closed and won't let water pass.

One RVer I spoke with said she could not remove it (I might have been able to but I don't put that kind of torque on somebody else's RV) She was able to reach into the vlave with a pair of needle nose pliars and rip the guts out.

(Do not take this next line wrong, She de-pressurized first)

Suddenly she was in hot water once again. (That is when she wished it).

She later did an advanced repair (Traded the TT in on a 5er)

But she was downright happy to be in hot water again.

suburan (Who made her heater) Said there was no check valve.

They spoke the truth, even if it was wrong, the check valve is part of the bypass system, not part of the water heater.

Thanks for the info- quick answer on how I winterize with the valve gone? (yes, ine valve) i don't. I use the camper year round-even in the heart of the winter snow skiing and in the three seasons I have owned this unit, I have never winterized
So, the valve you are speaking of is the one on the outside of the water heater, behind the access door? If I were to mess with that one, I need to make sure the range is purged of water, correct? Thanks

I think I have it down to the check valve, (from my research) but I can't seem to find where the check valve would be. Anyone?

Thanks!
