We bought a 2021 Coleman 274Bh Travel Trailer and unable to locate the water heater bypass valve. Is there a one in this model and where/how to find it?? Please advice.
The winterizing water heater bypass is usually on the back of the water heater. It may be inside a closed space behind a cabinet. Mine had about 12 screws to remove to access. I added a door.
I added a door to mine too! There are three valves at the back of the hot water heater. Go to the nearest cabinet near the hot water heater-look in there, add door!
Unless they redesigned it, with the water heater somewhere other than in the rear, the bypass is under the bottom mattress. Pull the mattress up to the left and there should be a section of floor under it to lift up. You will find the bypass there.
