Thanks guys, I will check it out tomorrow, I feel like an idiot though. I get down there and look at it, and it looks fine, no kinks, no visible blockages. I guess it is because I real do not understand how it really works. Am I wrong, it is just an intermediate between the fresh water tank and the faucets, it has no pump, it is pressurized by the water pump, and just holds and heats 6 gallons of water....

I looked at all the connections, even the release valve and it ll seems sound.

Yep, pretty much a simple holding tank. Pressure is from cold water inlet. The inlet pumps cold water into the tank at the bottom. Hot water is forced out the top (heat rises). So since you have good pressure on cold side, seems like some sort of blockage somewhere. I would guess it is closer to the tank though since it will build up pressure after a short time. It probably is filling up the pipes and building pressure and once opened, the pipes drain and there is not enough flow to keep it going.

Generally if there is no bypass kit, there should be no valves or anything on inlet or outlet. I suspect you have a bypass kit and something has gone wrong there.

Ok, I looked into it a little harder with all your suggestions. When I run the cold water side, the pump operates with a normal pump sound. When I operate the hot water side from the galley, I go back an listen to the pump and it seems like it is intermittent. it just clicks, like it is sputtering.

I must have a blockage somewhere and the water cannot be pumped clearly to the hot water tank.

Going to try and dig a little deeper. Thank you to all for your ideas on where to look.

I am going to try an back flush the hot water line back into the fresh holding tank. Seems like my only easy option. Should I just disconnect at the hot water pump and forcer water back to the holding tank or do it intermediately in one of the connections down the line first?
