RV Anti-freeze in your fresh water tanks when winterizing

[markopolo]

Do you put RV Anti-freeze in your fresh water tanks when winterizing or do you bypass at the pump?

When I use to use antifreeze, I disconnected the pipe from the tank and put it in the antifreeze jug. I then pumped it throughout the system.

Now, I use compressed air to blast the water lines out and put antifreeze in the sewage tanks to keep the seals moist.

My pump has a typical siphonhose that lets me fill the lines with antifreeze. Shutting the pump off lets it empty into the potable tank. Probably not needed, but better than an inch of stale? water.

You guys will have to show me the compressed air trick. Tried it and blew water all over the ceiling.

This winter was the first time we ever had to winterize a camper because we are winter "get outta Manitoba " campers and head to Mexico.
This year we came home in early February so had to winterize in Texas.
We did what the book says.
Now we have to reverse the procedure.
Hope we get it right!!!!

I dont care too much for the effects of antifreeze on the tubing and fittings used in fresh water systems ,even though its non toxic if it stains there must be some residue .On my coach I always evacuate with air pressure and leave it dehydated.This option is not on your vote list.REVCON372

I have to change my comment above. I use to use compressed air to clear all the water out of the lines. I've now switched back to using antifreeze.

This past summer, I had to replace the pump for my RV water system. At a little more than $100, I was not impressed. I pulled the pump apart and found that the pump diaphragm had dried out and started to leak. The water got into the pump bearings and rusted them seizing up the pump. By using the antifreeze, it keeps a liquid in the pump components preventing them from drying up. At least it's what the RV dealer said. So, now I have to really flush the system in the spring.
