H290 can't get water at wash down hose or rear shower cold

[danstanford]

Our H290 has a hot and cold shower at the transom and a wash down hose in the chain locker, both of which I haven't used till I tried winterizing the fresh water system. I got water/anitfreeze on the hot water side of the transom shower but nothing on the cold water side and could get nothing at the wash down hose. I see no valves anywhere, does anyone have any idea where I should start?
I have pink antifreeze coming solidly out of all other points so I can assume most of the system is winterized, but I really want to get these ones going too or I am afraid frozen lines will render the whole system no good in the spring.
I will try to trace the lines back but a quick run-through all access points did not show them at all.

Something isn't right. How did you winterize such that you are getting antifreeze out of the hot side?

simply dumped the antifreeze in the tank and ran the pump then started opening taps till i had pink coming out.

Geez Dan, there are better ways to winterize and save yourself some grief in the spring. Up to you of course, but what we have done in the past is pump as much water out of the fresh water tank as you can running your faucet no more than 10 minutes at a time. Once that tank is empty, I go to the hot water tank and drain that into the bilge. You can do that by opening the valve on the tank or pulling the cold water "in" hose off the hose barb. You also pull the hot water "out" hose off the hose barb. That will drain almost all the water out of the tank, what remains could freeze but should not cause any damage. I have a 4" piece of 1/2" copper water pipe that I use to connect the hot and cold water lines together, a couple of hose clamps and they are good to go. THEN you add a few gallons of pink RV antifreeze to your fresh water tank and run all the faucets until pink comes out. What that does is winterize your water system without filling the hot water tank with 5 gallons of antifreeze. Come spring, you pump as much antifreeze out of your fresh water tanks as you can, fill and flush several times with fresh water and a tablespoon of bleach. Once that runs clear and smell right, reconnect the water lines to the hot water tank and fill it with nice clean water.

Our h27-3 gave me fits this year with the weird mixing valve they had hard plumbed into the hot water tank. That is now gone as of this past weekend and I have the system plumbed and winterized as I just described to you.

PS. Regarding the no water situation, what do you have in the anchor locker, is it a spray head? We had three on our previous boat, all had almost no use but were clogged with nasty black stuff. I had to replace the entire sprayer to get water to flow. As far as the transom shower, I just replace the entire assembly on our boat a couple of weeks ago. For some reason ours was the hot water side and the actual valve was bad.

make sure you get all the antifreeze out of that hot water tank before you heat the water...i would flush it now if it were me and do a bypass on the lines
