Though we've owned our 2015 38RL for three years, this will be the first winter I've had to winterize, as we no longer live in it full-time.
I'm having an issue while trying to winterize using my air compressor. After emptying the water heater and turning it to "bypass", I'm unable to get pressure to build up on the cold water side. The hot water side works as expected. I've tried closing all the valves, including the low point drains, and I've closed out the valve to the water pump.
The one thing I've not done yet is to put in my new anode and heating element, as I am waiting to be able to get the water heater rinsed out of any remaining sediment in the bottom. Even though the water heater is in "bypass", could the fact that these two items not being reinstalled yet, be my issue?
I've added a picture of the valve I closed on the water pump to make sure that wasn't my problem.
Any suggestions would be much appreciated. This is driving me nuts....
