Re: Milky white hot water
if you just started using this season and stored the boat with rv antifreeze in the water system you will find it does this and will take a lot of water flushed thru to get it out (30+ gal) smelling it should tell if this is the case, also the fresh water tanks may still have some in them but flow clear when cold. For winter storage drain tanks & blow out lines it will save you this problem in the spring.
Oh, right! Good call. I assumed the OP had flushed his system already. I found it takes a great deal of flushing to push all the Propylene Glycol out of the system. You can tell whether any is left because of the change in taste. It took me 5 fill/empty cycles to get rid of the taste.
