Hot & Cold Shower

[WillieH]

Does anyone have problems maintaining constant water temperature in the shower ? ? I have a 2014 Precept and the water temperature goes from cold to hot every few seconds ! !

That happens when my wife runs the kitchen faucet!

WillieH, do you have a tankless water heater or a water heater with a tank?

We have the issue. It used to be much worse, very hot to very cold. The dealer replaced the mixer faucet. That lessened the problem considerably. It seems to occur when we are using the pump with water from the tank. When we are on city water the temperature stays fairly constant. The water temperature cycles with the pump turning off and on so it probably has something to do with water pressure, maybe a restriction in a water line or in the faucet itself. I have not noticed the issue in previous trailers we have owned.

Tankless !

Is it tankless? If so this is how we dealt with it. From my response on a previous thread:

We adjusted the water heater rheostat until the shower temp was perfect with only the hot water tap on. No input from the cold water. The tank then provides hot water without the typical hot/cold cycle everyone describes. We told the kids to take the nozzle down and turn on the hot water. Once the temp was appropriate then they could replace it and shower but not to turn the cold on in the shower. This worked well the whole week we were abroad. This seems to work fine whether on city fixtures mode and on normal operation mode (FW tank using the pump).

We had cycling hot/cold temps with ours. Solution that worked best was to remove water restrictor in hand nozzle. We enlarged the three small holes then reinstalled. Use more water this way but no temp flucuations.

We had the same problem with the tankless water heater on Precept 31UL. Required fixes were to adjust the water pump by turning the adjustment screw increasing the water pressure so as the pump runs smooth without surging. Still had a problem on uneven temp. then had to replace the temp/ECO switch sent from the Manf. Sorry no part#.
