Hot water bypass

[WolfmanMarty]

I took my trailer out for the first time and realized we never de-winterized it. I got everything working except cannot figure out where the hot water bypass switch is. Can someone help? I have a 2009 Sandpiper 255RLS. Thanks.

Not sure about your model but on mine it is a valve on a vertical pipe by the hot water tank. There is a valve to turn cold water input on and one to turn hot water output on. The bypass for the hot water is on the vertical pipe between the cold in and hot out lines.

This might be a dumb question, but how did you winterize it if you don't know where the hot water tank bypass is?

I just purchased it and it came winterized.

If you locate the heater access door outside, just go in and the back of heater at the same location inside is where you'll find the valves. Maybe behind a screwed access panel.

Found it hid after pulling out a cupboard drawer. But only one bypass. Did I miss one?

Change the valve position by 90 degrees, and try it. Some have a 3 way valve and a check valve on hot out. Same as three valves in function.

It's possible to have 1 or 2 or 3 bypass valves depending on how the RV
was built.

We can't tell you how many you should have. We can tell you if you
turn on your gas OR ELECTRIC to that water heater while the tank is
empty you will damage it.
Be SURE your water heater is full of water before you turn on any power
to it or try to fire the burner.
