I started to put a Bypass on my North Trail 21FBS hot water heater and it looks like it came from the factory with a Bypass. Does anyone with a 21FBS know this to be the case. Mine has three valves at the water heater. It looks like North Trail has saved me about 2 hours work in a hole that I can hardly get my head in. Happy Camping!!!!!!!!!!!!
