Using a hand pump siphon to winterize?

[acritzer]

My new TT has a hard to reach water pump. Anyone ever use a hand pump to pump antifreeze into the city water connection? If so, can you recommend one that possibly has a garden hose connection with it?

Thanks.

Thanks for the expanding on the issue, and how you dealt with it.

With the dilution, wasted anti-freeze and considerable flushing in the Spring, it is a poor way to winterize.

How did you get around the issue? Or was there even an issue since there was plenty of room for the water to expand?

I added more support under the tank and moved the pump pickup to the drain hose. If one knows that the tank is perfectly flat and level in both planes, and the pump will pull nearly all the anti-freeze from the tank, then I would accept this method. I send the anti-freeze in thru city water port.

I have only read of these things...pump and tank located under a sleeper sofa and haven't found any quick removal mechanism to get in and plumb up some sort of antifreeze hook up.

My camper didn't even have a hot water by-pass.

After I installed the HW bypass, the hand pump is awfully darn adequate.

Yep, it certainly isn't the best way. As you pointed out, most fresh water tanks don't lay perfectly flat and can cause problems. It also requires more anti-freeze before the pump will start pulling it from the tank.

I can see my entire fresh water tank as it is mounted upright in the back. Nowadays many are under the bed in full view. And in both cases have low point drains leaving no water at the bottom.

Real sorry to hear your tank is defective and sagging between supports and leaves water at the bottom. 😞

But you defective tank does not equate to the fact that others should be told it is a poor way to winterize. To each his own. Whatever works for you!!:W

I winterize by adding anti-freeze to the fresh water tank. And pump thru lines this IMHO, JMHO insures me that the antifreeze gets completely into my water pump. The one year I did not do it this way the following spring I had to replace the water pump. 😞

That all said. This is what I finally found to get antifreeze in a pesky placed water inlet.

It bends in all ways will add water even in a 45 degree angle! AND expands and contracts to just about any length configuration you need. Then held upright and pour away.



Couple of bucks at walmart in automotive department.

The OP has a pump that's hard to get at. As we looked at RVs (specifically small Class Cs) last year, I began to notice a trend towards making the pump difficult, if not impossible, to access for winterizing. Which is STUPID since more than half of the USA and certainly Canada, have climates that require RV winterization.

Our old Class C had the water pump right at the freshwater tank, easily accessible from an outside basement door. Yes, a 3-way valve makes this necessary chore SO SIMPLE and quick.

I have always used a manual pump to push anti-freeze thru the city water port.

You could winterize the whole unit this way if you wanted to.

Don't forget the exterior water quick connections! Those REQUIRE pressure to force the water out.

A hand pump is not exclusive to RV's. Any auto parts store will have tons of types of hand pumps as will all the big box stores.

[fj12ryder]

I use a funnel. Works well and cheap too.

Whoops, misread about the city water port, I was thinking of fresh water port. Sorry.
