hose fitting
on the starbrd and port side just abaft the forward vent ducts on my 72 f-31 are found a type of hose fitting set in the depressed center of an approx 3" sq plastic base. were these an option and for what ? dean price
Sounds like a dockside water hook up to me but it may be something else since you say you have one port and strb, usually there is only one. The only other thing I can think of are tank vents. Can you post a picture. It would help identify it. If it has a regular garden hose fitting on it then I suspect it`s what I`m thinking; a dockside water inlet that is tied into your potable (fresh) water system. It will be tied into the plumbing after your on-board water pressure pump. This way, the pump`s built in check valve prevents shore water from filling and overflowing your water tank. It`s important to note that some of these units will have a built in pressure regulator to protect your system from high marina pressure surges, and they should also have a check valve to prevent water from exiting when there is no hose hooked up and your on board system is pressurized.
There are also units that are used for washdown where raw water from under the hull is pumped up to the fitting but they are typically not in an integrated recessed housing. These will not have a regulator or a check valve built in and there would be a pump somewhere on board hooked up to a seacock.
Both units must be included in your winterizing routine. Some blow compressed air through thier system to get rid of all the water (caution with your pump here), others pump non-tox (plumbing) anti-freeze through the system. Which ever method you use, in the case of the dockside water hookup fitting, you must ensure you pass air or anti-freeze from the outside into these units as their check valve will not allow trapped air or water in the line from the unit to the rest of your plumbing to escape out the fitting, thus water will be trapped there. Any water left in the regulator over the winter will ruin it, the check valve and the housing.
