Problem - Cold water turns hot????

[Chris Reinke - CD330 Inni]

I have a bit of a problem on my CD330 and I am hoping the knowledgeable readers of this board can offer some corrective suggestions. The water supply manifold and tank control valves on my CD are located outboard of the port engine compartment bulkhead. The supply line then run up through the bulkhead to the pump which is located on the port bulkhead inside the engine compartment. My problem is that the engine heats up the water as it passes through the engine compartment to the point where it is dangerously hot at the galley sink. I often have small children cruising with me so I need to rectify the situation. Can anyone offer a reason as to why the pumps (water and shower sump) should be located in the engine compartment? Can anyone offer a reason as to why I can not relocate them to the outboard side of the bulkhead? Alternatively, any suggestions as to a good insulating material which can withstand the heat of the engine?

Any suggestions would be appreciated.

Thanks and Happy Sailing,
Chris

Chris,

Our 330 is configured in exactly the same manner as are the other 20+ sailing around out there. Whatever is causing your fresh water overheating, it isn't the location of the water pumps. Your engine is either dangerously overheating or something else has gone amiss. After Floyd hit Maine last summer, we had to motor for seven hours or so per day in order to get back to Robinhood on schedule. No heating of fresh water unless we wanted hot water from the water heater. Your engine temp should be no higher than 190 degrees and then only under extreme conditions. Unless it's hotter than Hades, the temp should be around 165-175.

A thought. If the water isn't hot in the head sink (separate cold and hot water faucets) but is in the galley sink (one of those single handle combo faucets), the problem is in the galley faucet.

If the problem is in both the head sink and the galley sink, I'm stumped!

Let me know what you figure out.

I received a reply via E-mail which offered a possible cause and I believe we have identified the problem which I would like to share. The water supply hose which runs off the pump discharge goes to a "T" fitting which seperates the hot and cold water circuits. A one-way check valve is then installed on the hot water supply side of the fitting to prevent heated water from flowing back into the cold water circuit. My father ran out to the boat this afternoon and confirmed that the previous owner had removed the fitting for an unknown reason. The hot water would then flow from the hot water tank back into the the cold water circuit as the cold water pressure would drop when the facet was opened.

Thanks to everyone for the comments. I knew I could count on you,
Chris
