It was as simple as just turning them 90 degrees so they are pointing into the water heater. I bought the camper brand new and it was given to us this way. They told us they tested for hot water so we never figured they'd turn the valves (nor did they tell us that). Maybe they didn't even test for hot water and that was a lie? Anyway, everything is good now. Had to replace the element (no big deal). Thanks for everyone's responses!Re: RV Hot Water Heater wa8yxm wrote: THanks for the photo. There are 3 hot water bypass systems used in RV's. I will explain why later 1 Valve 2 Valve (what you have. I"ve never seen one before) 3 vlave (What I have) The two valves one hot and one cold are 3-way valves. Now USUALLY you turn the valve to where you want the water to flow.. Turning the cold valve one way water flows into the heater tank. the other way into the bypass hose and likely ther eis an OFF too if its not locked into 90 degrees. Same for the hot but the flow is FROM the tank/bypass WHY. Well to give you an example.. Last April I figured it was warm enough and headed north. .SURPRISE. well below freezing long about Ohio. So i put my vlaves in BYPASS and opened the water heater drain.. Saved on propane to keep the water wet instead of HARD (Hard as Ice) I have seen what happens when you freeze a full heater.. (Thankfully it was not MY heater). Thanks for your response. So do you agree that both valves should be turned in the same direction?Re: RV Hot Water Heater Old-Biscuit wrote: DO the valve handles move so that they POINT inward towards the water heater tank? Cold in thru bottom and hot out thru top Not sure about that yet. I'm going to test things out this weekend. I will let everyone know the results. Thanks!Re: RV Hot Water Heater beemerphile1 wrote: BB_TX wrote: Those are standard 3 way valves. The direction of the handle indicates the direction of water flow. Shown in position to bypass water heater. Turn both 90 degrees to flow thru water heater. I agree with this, I would turn each handle 90 degrees. That was one test I did before I gave up originally. I turned the hot water valve 90 degrees and had the hot water side of the faucet on. The water started sputtering and eventually stopped.Re: RV Hot Water HeaterThanks everyone for your responses so far. I'm going to run some additional tests with your information and see what happens.RV Hot Water HeaterJust bought a new RV. We've had one before and hardly had any issues. One issue I'm having with the new RV is getting hot water. I've attached a picture of the setup for the hot water tank. To me, this doesn't seem right. I'm not even sure if the hot water tank is filling up either. Any input would be greatly appreciated.
