Hack #21 Winterizing Easy Steps.

Here’s a great write-up on winterizing your MLE22. It is good for any RV but specifically detailed for the Grand Deign XLS 22MLE.
Thanks to Dean Baker for posting this on the Grand Design Imagine XLS 22mle owners Facebook page and letting me copy it.

First, drain the entire water system.
Step 1:

I changed my drains to use valves in  Hack #15 :
Step 2:
Drain the hot water tank. Remove the white PVC plug.
I added a braided hose and valve for this in  Hack #14.

Step 3:
Change the water heater line vales for winterized setting.


Close the Inlet and Outlet valves and Open the Bypass valve.

Step 4:
Set the Winterizing valve near the water pump.
The water pump is under the dinette bench seat nearest to the pantry.

Step 5:
Place the feed hose into the pink stuff (RV Antifreeze).

Step 6:
Close all the drains and low points.
Step 7:
Pump it in.

Turn on the water pump and open one faucet at a time.

Remember the exterior faucets and to flush the toilet to fill all water feed lines.
That’s it. Your ready for winter.
