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.

Re: Milky white hot water

You are probably right about the glycol. I didn't know it took so many cycles. I did only two so far.

I forgot to mention that the hot water does not seem to work on 110 so while I was running the hot water it was not actually hot.
I was wondering if burned up electrodes could get in the water.

Re: Milky white hot water

I drain my hot water heater each fall rather than fill it with antifreeze. In the spring, the hot water is always "milky" until the air in tank is completely flushed. From your description I would guess that's what you are seeing.

Re: Milky white hot water

You should also get in the habit of using the hot water faucet even when there's no hot water. It keeps the water moving thru the heater all the time. And while I'm not an expert on winterizing, from what I've read on these and other 'boards, it makes little sense to fill the tanks and pipes with antifreeze, just empty them and you don't have the problems in spring time.

Re: Milky white hot water

Stu, in theory that's a great idea, but there's a problem or two. First and foremost, most systems are not completely emptied when drained, mainly because the hoses go uphill, downhill, around bends, through fittings, etc... Consequently, there's always a bit of water left in the system, water that will surely freeze, expand and bust something.

Next, the water is heated by the engine, passing through a cast iron manifold, which will rust like crazy if it's not protected by the rust inhibitor in the antifreeze--not a good thing.

Most of the pink, marine antifreeze solutions are non-toxic, but they have little in the way of bacterial inhibitors. Therefore, I usually add a cup of Clorox bleach to the winterized tank along with the antifreeze--something to kill the bugs. I do not, however, add the bleach until after the antifreeze solution has been thoroughly been flushed through the system. The bleach is then added to the tank only. Bleach can do some nasty things to metals as well.

When spring arrives, I pump the entire system dry, then fill the 70-gallon tank with cold, fresh water, and flush the entire system again, running the pump until the tank is empty. Then I refill it one more time, this time, though, adding a cup to bleach to the 70-gallons of water. This keeps the bug count down, but it's not strong enough to hurt the engine parts or electric water heater.

Good Luck,

Gary

Re: Milky white hot water

Sounds like the same problem we had this weekend after de-winterizing Utopia...we had an air leak, Captain went in, found the leak and had it fixed it in no time flat, after that water was crystal clear!!

Re: Milky white hot water

Or install a by pass at the water heater inlet and outlet. Any RV store will have it. After you drain the system of water, switch the valves, and fill the system w/ antifreeze. Saves filling the heater and makes flushing in the spring simple.

I always remind my cooks and students, there is only two places we ever use hot tap water in the kitchen, the hand sink and pot sinks, water used to cook with should always be cold tap water
Why use cold water for cooking? I thought using already hot water saves on energy. Please advice. I often prepare food onboard.

Re: Milky white hot water

Thank you all. Problem seems solved.
I put a hose in the tank and ran the hot water faucet, without the heat turned on, until it ran clear.
Seems to be OK now.
Took longer than I would have suspected.
