hello all, We're in the process of our 1st time winterizing a 64 Overlander. We're pretty sure we have NO bypass for our Water Heater. (Looked all over, can't find anything, so we're assuming there are no valves for bypassing.)
We also have no time to install a bypass right now, we have to be in storage in a couple days. We did find the low point cold-hot drains. We did find the water heater drain. The drain from the fresh holding tank is locked up and will not open, so we have no way of draining the tiny amount left. Will this really hurt??
Is it ok to let antifreeze go into the Water Heater??
( From what I've read it is ok, just takes alot of jugs of antifreeze to fill the system. correct?)
If the above is correct, I'd rater not use 20 gallons of antifreeze if not really necessary. Is blowing out w/ compressed air at 40psi and then leave everything empty sufficient?? Or should I break down and buy a huge amount of antifreeze?
I see some peoplejust doing the air, then others do the antifreeze. Im in central Illinois, pretty cold area.
and just to make sure Im correct, I blow the compressed air in thu the city water line, right?
