Why not spend a bit on a couple gallons of RV antifreeze and be 100% sure your are ok or blow out the line and HOPE you got all the water out? Barney

Many don't like the residual taste of antifreeze - and in the PNW we get the occasional warm weather during winter and it's nice to be able to add water and go camping w/o all the flushing.

If you can taste it you didn't flush it good enough.

For some folks, they may have a far less "tolerance" to taste/smell and may be highly sensitive to what does not bother you..

For instance, my Mom (RIP) used to drive us crazy, insisted that we only buy her ONE specific brand of milk after she gave up driving. She could not stand the taste of the different brands of milk. Could not buy it at our corner store 2 miles away, had to drive 20 miles away (one way) and HOPE the store had it in stock.

We could not tell much if not any difference but my Mom COULD.

Milk now days is stripped down to the separate parts, each dairy has their own "formula" and method of "adding back" these parts at the ratio they want and blending it. DOES make for some very slight different taste. While it was not an issue for us, it was for my Mom.

We didn't POO POO her for her milk choice like you are POO POOING other folks here for not wanting the antifreeze taste..

Plastic ABSORBS CHEMICALS OVER TIME, even chemicals which are inert/harmless. It takes a lot of time and water to clear MOST but not all of those chemicals.

Some of the remaining chemicals left bound to the plastic will slowly continue to LEACH back into your drinking water. That leaching can influence the taste for some that are hypersensitive to it.

Myself, we don't drink from our RV water system, we buy bottled water for drinking, cooking and ice. We do that because quite frankly we do not like "city water chlorine taste" that you get from any campground that has municipal water or treats the water with chlorine (we have a deep well at our home and not city water).

I don't prefer to pump the system full of RV antifreeze when over 15 yrs I have only had ONE issue with a frozen line and that was my stupidity for closing the manual shut off valve to the toilet. Have not ever repeated that and the lines have not broken.

People around this forum act like a broken line is a huge expensive ordeal, it is not, PEX is cheap and easy to work with and with sharkbite fittings can easily fix a broken line in less than 5 minutes.. PEX also is quite tolerant for flexing caused by ice expansion when compared to copper lines or the old Quest (grey stuff) plastic.. And by the way, my TT HAS the ORIGINAL 35 yr old grey Quest stuff which was badly maligned to be "brittle"..

Most RVs run the water lines along on top of the floor in a chase and are not all that hard to get to so replacing is not all that hard to do. The only items to be concerned about is the water heater and the toilet valve, those are not easy and can be costly to replace.

But as I have said, if you are not comfortable with air only then by all means use the pink stuff.
