Best source for raw water system antifreeze?

Could save a little bit and buy a small compressor from HF to blow out your fresh water system.

Been doing this that last 2 years and it's been great. I spent less money on a small compressor then 4 gal of antifreeze during the days of supply chain issues.

For future reference, how did you connect the air hose to your system? I assume you ran out as much water from the system as you could and then used some type of airtight fitting to connect the compressor hose to the system. it makes a lot of sense because that’s what they do with yard irrigation systems in my area.

It's funny, I know people just blow out and go. But I still hesitate to leave it like that. I worry about low spots or dips in a line where the water could re-collect so I still use the pink stuff. Air can sometimes blow past water inside a hose and get most of the water... but then any remaining water can drain back and collect.

Maybe I'm an old dog - but I've done it this way (pink stuff) for decades with many, many different boats (and cottages) and I just can't seem to work up the nerve to try a different way.

Your boat, similar to my old 260DA, is pretty easy to work on. I would just take the water line off the fresh water tank and stick it into a pail of AF - essentially using the pail as my "water tank". Still bypass the hot water tank, though.
