We had a really cold snap here in Va. that caught me off guard. I managed to blow almost all of the water out of my lines using a portable 10gal. air tank.
However, I would like to put a water heater bypass on the tank. I have a diverter valve to allow the water pump to pick up A/F already installed (since the pump is easily accessible under my bed).
My difficulty is accessing the outlet of the WH. The tank is partly acessible from under the bed.
Here is a pic showing the small panel to the left under the swatter that is situated in front of the WH outlet.
Here is a view of the raised bed.
You can see the AC element. The cold water inlet is just below it and slightly to the right (hidden by the PO high-tech insulation).
I stuck my camera under the bed and pointed it to the right. This is what I can't get to.
Seems easy in the pic, but reaching under the bed, I can just touch the red fitting.
My plan at this point is to lift up the carpet next to the bed and make an access by sawing out the panel above the outlet. You can see in the above pic that someone cut a round hole as access, but it isn't large enough to get two hands and tools to the fitting. (And it's covered with a piece of cardboard - jeeze, I hate half-a$$ed work)
I found this online and think the 12" kit might do the job -

My only concern is the angle of the outlet and the rigidity of the plastic water line may be a problem.
