I live in Canada near Ottawa, and I will be leaving our Sunseeker 24 outside this winter. I went to Canadian Tire to buy some antifreeze to put in the waterlines for the toilet, shower etc and the clerk said to use some windshield washer. Is that good or bad advice?
Last year, I bought some Hall-Chem "economical plumbing antifreeze" that contains non toxic Ethanol and propylene glycol.
The stuff I am thinking of using is labeled "all season windshield washer fluid -35" but says POISON, so am somewhat concerned/doubtful... It doesnt say what's in it. It is blue instead of pink.
If it's just going down the toilet or shower drains, it should work to resist freezing in the traps. I think someone said in an emergency?
The concern is what the ingredients in the ww antifreeze might do to the seals and valves it will come into contact with downstream. Pure alcohols will cause harm to rubber, and who knows what else, in the short plumbing run from those appliances (shower/toilet) to the exit drains.
The pink stuff usually has added lubricants, and is less likely to damage plumbing componenets.
If you can, use the pink stuff, before the blue stuff.
