Heres a quote from first page of thread: 3) There should be a valve near your water pump; one way goes the the fresh tank and the other to a short hose. Turn the valve to the short hose. This hose will be used to suck the RV anti-freeze into the system. 4) Buy about 3 gallons of pink RV anti-freeze 5) When I tried this it would not suck the antifreeze at all. I even went and put a gallon in thre fresh tank and switched the valve to the down position and it still would not suck the antifreeze in. So after messing around, I disconnected the hose to the pump and only had a smaller diameter hose and had to hold it against the pump to make it suck the antifreeze and it worked! Why would it not take when I had the valve turned on the short hose or to the fresh water tank? I even took it off and blew in it and it was not clogged.
The only thing I can think of is your 3 way valve does not work. I would take the siphon hose off, and look at the valve as you turn it to see if it is working.....be sure there is no pressure on the line and wear safety glasses.
A gallon of antifreeze in the fresh water tank might not bring the level up to the pick-up tube.
