16 xrb suction line for winterizing

[BigGrover]

Anyone out there with a 16 xrb able to tell me where to find the suction line for the pump is to add antifreeze? I cannot locate one under the trailer or under the seat. Do I have to disconnect the inlet line or just dump antifreeze in the fresh water tank to pump it through the lines?

Thanks

First you will have to locate your water pump, if you don't know where it is run it and trace the sound. Once you find it there will be a T where the water line comes through the floor from the water tank, turn off the valve coming through the floor. On the other side of the T you should have a tube a few feet long with a valve in it that is open on the end, open that valve and put the line in the antifreeze jug, turn on the pump and run through the system. here is a picture of a basic water system at the pump.

For my 2016, it's under the forward dinette bench, left panel that has screws in it. See star below - clear hose open on one side.

Mine is in the same spot as M&A's.
