RV anti-freeze taste

A lot of people don't realize that there are two types of "pink stuff" available, the cheaper ethanol (alcohol) based version and the better propylene glycol based version. The two types are explained here. Propylene glycol is not toxic and should not be confused with automotive antifreeze.

The good RV stuff (propylene glycol based) can cost a little more but for the jug or two you need, it's insignificant. It can be harder to find because most vendors stock their shelves with the cheaper product. I found a great price at a local independent RV repair & parts shop last fall and bought enough for 3 or 4 seasons. You also need to read the fine print on a label as it's not immediately obvious which type it is.

If you want to get rid of the odor, lubricate seals and not have to worry about flammability, use the good pink stuff.

People tend to forget that they could just drain off (or blow out) the pink stuff immediately after running it through the system. You're using it to displace any remaining water. Once you've pumped it into the system, it's done its job. Drain it. Maybe no bad taste that way? x4 on the baking soda. Also the cheaper pink stuff usually has alcohol in it. Could this cause it to impregnate the plumbing?

And that's the ticket. Baking soda.

I use mine numerous times a winter also.

That's the main reason I DON'T use any pink stuff, just blow the lines clear. Putting the water system back in service requires nothing but adding water to the tank.

I've got enough on my honey-do list, I don't need to add extra work like rinsing, cleaning, sanitizing and getting rid of funny tastes.

I just blew out the lines on our coach two years ago while leaving it in South Carolina for a trip home to Montreal. A plastic fitting in the wet bay froze and split so since then I have been using the pink stuff all the time. Never thought I'd have that issue in South Carolina after blowing out the lines.

I had the same thing happen once.
Turned out to be the tiny bit trapped in the low point drains that I had failed to flush.
Every time water was run a tiny bit was siphoned out that was just enough to taste.

Similar situation but it was coming from the winterizing/syphon line. Now I draw about a quart of water through this line, all clear now. I also let fresh water flush out the low point drains.

This is the reason we don't use the pink stuff! I just do a very good job of blowing the likes. Pink stuff only in the drains. I use water from the tank or park whichever is more covenant. The water in your tanks is as good as any tap water, and as good as bottled water.

The power of American advertising just amazes me!!

Blow Baby Blow! Never a problem with just air.

Now the trailers in my fleet were older but it appeared to me that the antifreeze soaked into the lines then when it got hot outside some would leach back into the water flow. Once the weather got hot it seemed like every time the trailer set for a couple days the water tasted like antifreeze and was also foamy coming out of the faucet. So about 10 years ago we stopped using antifreeze and just blew the lines which with 30 trailers made since anyway. I don't put antifreeze in my own trailer lines just for this reason. 30 trailers setting outside during harsh Utah winters and we never had a problem with freeze damage.

After I use chlorine I then flush with some baking soda. Maybe that would help

X2 baking soda has worked the best for me. Even removes the chlorine taste.
