Winterize Problem on Cruiser Aire CFL29
Hello,
When I winterize my Cruiser Aire CFL29 I drained all piping hot and cold water and also drain the hot water tank. As I mentioned, I turn both taps near the water heater and installed a short RV antifreeze sprinkler hose to the container. I plugged the control to position '' Winterize 'and started the water pump. OK to leave antifreeze in the cold water network. However, for the hot water system, antifreeze does not come out of the taps. Antifreeze goes into the hot water tank and exits through the drain drain.
Attached is a photo of the two valves to operate the 'Winterize' 'and a drawing of the configuration of the pipes of cold and hot water.
What's the problem?
-Is It lacks a tap near the exit of the hot water tank to prevent antifreeze to go into the hot water tank?
-Does He has a check valve that is not working at the exit of hot water from the hot water tank or he should have one and it is absent?
Thank you in advance for your experience
