Hot water heater problems in a Cherokee 274vfk.

We purchased a new 2019 Forest River Cherokee 274vfk. We love everything about the RV except for the performance of the hot water heater. Our previous Starcraft RV had a manual-light gas 6 gallon Suburban hot water heater and my wife and I could take showers one after the other and never run out of hot water. The Suburban hot water heater in our new RV is also a 6 gallon Suburban gas & electric but it won't put out enough hot water to get through even one military-type shower. The burner lights and the electric element will power on.

When I was winterizing the RV, I turned the bypass valves on the inlet and outlet of the hot water heater but there was no third valve in the bypass line. I called the dealer and was told that there was a check valve in that line next to the water heater. I don't see how a check valve could work as the flow direction is the same through the water heater or the bypass hose.

Anyway, I'm going to install a manual valve in the bypass hose. I think that this is going to fix the problem with the hot water heater.

Have any of you encountered this?

Did you check the outside shower? What you are describing can be caused by the faucets in the outside shower bring open.

We have had both the two and three valve shut off "bypass winterizing" valves. Both work fine. There is absolutely no difference in the performance of the systems when water heater in actual use.

As others have mentioned check your outside shower valves.

Thanks for the tip. However, outside shower valves are closed and not leaking.

Our hot water heater has the same setup, so I guess the valves are two-way valves.

I have everything drained and winterized so I can't troubleshoot any further. Looks like I'll be doing some more troubleshooting as soon as winter freeze season is over.

Thanks for your response!

Most outside showers have a shut off valve in the shower head and will shut off the water ( no leaks) even if both the hot and cold faucets are open. If those valves are open cold water will mix with the hot and can cause the issue you are seeing.
