Water heater bypass

Looking for one on my 02 Monaco. No mention in the owners manual.
Maybe it didn’t come with one.

I do believe not all have it installed, but a simple search brings these.

For MHs
Many times the water heater bypass is NOT located at water heater but inside a storage compartment
Some are on the water panel
Is it time for YOUR Medication or Mine?

If you have an on demand water heater there probably is no bypass. Mine doesn't have one. If it is a tank heater, it would be on the back of the unit. There should be a panel inside the motorhome that can be removed to access this area. You would find the valves there that would direct the water/anti-freeze accordingly.

My current coach, prior coach and before that travel trailer all have/had propane water heaters. In each RV, the "plumbing" at the water heater had heater isolation and by-pass valves. If your coach has a propane water heater with tank, it should have a by-pass located very near the tank.

This is an image of the typically plumbing, including by-pass valve, for a propane water heater. Hope this info helps!
