Hot Water Heater Pressure

We recently purchased a home that was built in 2007 and really was only lived in by one previous owner for about 60days. It is a two story house with two hot water heater, I believe one controls the down staris and one controls the upstaris. Everything downstairs works except the shower in the Master Bath. It seems to take a while for the hot water to come. When you turn it all the way to hot it looses water pressure. I can deal with that but the upstairs is a differnt story. The sinks all work great no problem with pressure or with hot water, but the showers do not get hot at all and when the shower faucet is turned all the way to hot no water comes out at all. Both water heaters are Rheem and Rudd Water Heaters and are new. I am not a plumber and they are both gas heaters, so I am causious about messing with them. Anyone who has any experience with them please feel free to comment on your past experiences or any knowlege you may have.

Plumbing problem

If you get good hot water at the sinks, your water heaters are working properly. It sounds like there is a plumbing problem in the house -- the showers are not plumbed properly. If you get no hot water with the shower faucet on full-hot and the water stops flowing completely, check the shut-off valve for the shower faucet. (There may be a panel on the wall of the room on the other side of the shower. Open that panel and look for shut-off valves. All modern plumbing should have shut-off valves for all the fixtures.)

As for the volume of water flow, again, this sounds like a plumbing problem. Either your faucets have restrictors in them, or the plumber installed the wrong diameter pipes, or the shut-off valves are not fully open. It would be a real surprise if low flow of water was caused by a water heater -- unless you're trying to run several bathrooms simultaneously. The first thing to do is to track down all the shut-off valves and make sure they are fully open. Every sink, every shower/tub, every toilet, every faucet should have shut-off valves. Find them and make sure they are turned fully on.

Good luck!
