Foamy Water

if the foam goes away quickly it may just be air in the lines. Both hot and cold, or just one? If the foam persists you got something in the water, may want to flush and purge it out.
Found this on an RV site:
"It's just the residual pink antifreeze coating the inside of the pipes. Acts like a little bit of soap in the water, creating the foam when it passes through the faucet aerator. Eventually you'll run enough water through the pipes to wash it all away. Nothing to worry about, the pink antifreeze is non-toxic and as you found dissipates after you use the system for a while."

Yes, but why is getting the antifreeze foam in August? May I understand, but not now. Did he just now start using the boat? If no, then maybe look at his water source.
I notice that too in the spring, but it goes away after a while. We're in Michigan, so yea, there's pink stuff in the lines. Maybe the OP put pink stuff in the tank. I haven't done that in decades. Seems to take all summer to get the taste (and foam) out. I pull the hose off the tank and let any remaining water drain out, then put the hose in the AF jug and run the pump to pickle the lines. Uses less AF, and there's none in the tanks. There will be a tiny amount of water left in the tank, but it has lots of room to expand when it freezes so it won't hurt anything. It's that tiny amount that takes all summer to dissipate of it has AF in it.
Do you have 2 water tanks, and maybe just now switched to the 2nd one you've not used since winter?
Fill the tank(s) and empty them. Use every faucet you have. You may have to repeat a couple of times. That will flush the tanks and lines.
When you winterize, do you put the pink stuff in the water tanks and then run it through the lines? Or do you disconnect the tank and run it through the lines?
If you put AF in the water tanks, it will take many flushing and complete flushing to remove it all. Better to disconnect the line from the tank and put the AF in the lines. If there is some residual water in the tank, it will freeze, however it will not do any damage because there is plenty of space for the water to expand in to.
I have the same problem with my 2001 390. I don’t think it have anything to do with the tanks because that’s the only faucet that have that problem out of 3 faucets. I thought it had something to do with the solenoid valve for the freshwater to the head which is splice into that line.

FWIW, I do this twice a year and also anytime I have received water from a questionable source.
