I bought the RV anti-freeze from Wal-Mart (the pink stuff). The label said do not dilute and 2 gallons is enough for the average RV. Not wanting to make a second trip to Wally I figured I should get 3 to be safe. 7 gallons later I finally got enough to prime my pump and purge the pipes. I had the hot water heater drained, isolated and bypassed; I had the fresh water drain tank valve shut and the pipe drain caps on. It was a long day. This is my first time winterizing my TT. Is this normal?

OH! I know it is early in the year to winterize, I am going overseas.

I can get by with 1 gallon on mine. It is only a 23 ft Class C with usual equipment. I unhook the hose from the water tank to the pump, put the hose directly into the antifreeze jug, bypass the heater, turn on the pump and in about 5 minutes I'm done. Pink stuff coming out all the taps and toilet. This usually takes about half the jug and the rest I pour into the sink traps.

2 gallons is about right on to do the average RV. I'm surmising you added the anti-freeze to the fresh water tank. What you might try next time is rig up a short piece of hose and a couple of fittings so the anti-freeze can be sucked right out of the jug by the pump. It works great and you can winterize in a very short time. It takes me about 1.5 gals. to do a 21' trailer.

Pumping out of the jug is good advice. You still want to put a gallon in the tank. There is a little water in there that can't be drained. Later! Lone Eagle

I cannot believe any 27 footer can use 7 gals. My 30 footer uses only 2 or 3 gallons. I never use the water tank, put fill using the city hookup. I always blow out the lines before I fill. Maybe yours took so much because it was being mingled with the clear water and took a while to come out pink? Even with the blowing out the lines, it takes a while before it comes out real pink.

1.5 gallons seems to be average. Sounds like you didn't by-pass the hot water tank.
I never put any anti freeze in the water storage tank, if a little is left and it does freeze there is plenty of room for expansion.
Usually takes me about 10 minutes to install the fluid.

Your problem was that you poured the antifreeze into the fresh water tank. It took 7 gallons to get the liquid to the pump. The outlet from the tank is not completely on the bottom of the tank and the RV may have been leaning slightly away from the pump side of the tank. In the spring you will have to flush out the fresh water tank really well and add some baking soda to help eliminate the antifreeze taste. Next year do what the other posters said and remove the hose that goes from the water tank to the pump and connect a hose from the pump and put the other end into the antifreeze bottle. Turn on the pump and open all the water valves until they run pink. Then take some antifreeze and pour about 1 cup into each drain and don't forget to add a little to the toilet bowl to keep the rubber seal from drying out. You shouldn't need more than 2 gallons to do the job. Also make sure the water heater is bypassed.

there is a kit you can buy[or make it yourself. it basicly is two valves and a couple feet of hose. you use it to bypass the fresh water tank and suck the antifreeze out of the bottle. also you could use a fiting to screw on to the city water inlet and blow out your lines first. you will need an air compressor to do this. set regulater to 30# and open each faucet one at a time. make sure that there is allways one faucet open at all times. also rember to do the toilet, both with air and antifreeze. hope this helps. whoops almost forgot the outside shower *This Message was edited on 24-Aug-02 09:29 PM by ford1228*
