Winterizing 2010 Roo 21ssl - Issues

[upnorth]

Anybody know where to locate the water heater bypass? The user manual is not very user-friendly and I've pretty much taken apart every panel in under the sinks.

upnorth,

Welcome to FRF.


The by-pass is directly behind the water heater tank. Take note of the location, from the outside; and go inside in approximately the same area. It'll most likely be behind a false panel.

Inside the trailer find your hot water heater. It should be plumbed into the water system at your hot water heater.

My 2010 23SS must not have the one way check valve on the hot water line. There is a valve similar to the valve on the cold water line and the by pass on the hot water line. I wonder if they ran out of parts and kept the line building trailers in as creative a way as they could? Makes ya wonder.

where is water heater by-pass valve ?

There are 1 2 and 3 valve designs. In my post I show pics of the 1 and 3 valve designs.

Hi Doc, Are you sure your 23SS doesn't have the check valve. I have the same set-up shown in the pictures above and on my first attempt at winterizing the antifreeze was getting past the check valve and coming out of the water heater. The hose kept slipping out of the antifreeze so I can only assume the air mixed with antifreeze wasn't building up enough pressure against the check valve. I tried the process again with water and it worked fine and then with antifreeze and it worked fine again.

Just glad I didn't need to start cutting and add another valve if I didn't need to.
