Question: How long does it take in flushing the lines out for the bubbly effect of the antifreeze to get flushed out?RV was in the shop last fall so we had a pro winterize it at the same time. Years past we've just blown out the water lines and dumped a few bottles of antifreeze in the traps & holding tanks. This is first time the water lines were 'antifreezed'.I've run three full tanks of fresh water thru the water lines and it looks clear enough but still comes out bubbly, way more bubbly than what the aerators make it. Not as bad as when I started but still...

You shouldn't taste it much after a few gallons, unless some dumkoff poured water into your fresh water tank and ran the pump, even worse if you got some antifreeze in your hot water tank too.If you can taste it still... some places that can be missed when you de-winterize it... the water fill for direct outside connection. If you are filling your tank and running the pump, drain off the pressure completely, press the check valve on the side of the rig where you connect the hose, then have someone start the pump. Pink?

Just because you paid a shop to winterize your RV, doesn't mean it was done by a pro.Personally, I would keep flushing the lines and FW tank until you get everything out. Then next winter go back to blowing out the lines and using pink stuff in the traps.I've been doing that for years.

I tend to blow the antifreeze out, with pressurize air, the same way I blow out the water in that fall. If I do that then it only takes a few gallons and I am good to go. I found when I didn't blow it out first the taste was there for 3 or even 4 tanks worth of water.

We go one step further and not use the water tank for consumption or cooking. Bring along bottle water for that...Got to have our same brand of bottled water to make our same good taste to grind and brew fresh coffee everyday.I know there isn't anything wrong with the tank water - just never got into drinking any of it...Roy Ken

It depends. Was the antifreeze poured into the tank or run directly into the lines? If in the tank it will take a long time because you are only diluting it each flush.If they used the correct stuff it is not toxic. Some coffee sweeteners use the RV antifreeze as the main ingredient.Don't forget to sanitize the tank and lines before use.
