Looking at the one under the refrigerator I see a small electric pump with one valve cut off. Can someone tell me about this one? It appears that beside the cut off valve there is a piece of clear tubing hooked to it. The thing I don't understand is that one end of the tubing is open. What does it do? What is the electric pump for and what happens if I open the valve at the tubing?
At the input for the water pump, the original owner installed a winterizing valve.
When switched one way (normal), it sucks water from the fresh water tank and feeds it through the system. The open tubing is cut off and not used.
Switched to the other direction, the fresh water tank is cut off and the pump sucks on that open tube. If you put that tube into a gallon of RV type antifreeze, it will suck it out of the gallon jug and winterize your water system.
