    Installing city water intake on 3888-gctid391319

    Our 1990 3888 never had a direct fresh water hook up. Now that we are having a leaking fresh water tank problem it is time to install one. At least it will get us by until we figure out what to do about the leaking aluminum tank. I understand you have to "T" into the cold water line on the other side of the water pump. How have others ran the feed line to the back of the 3888's and where have they mounted the exterior hook-up? Any help would be great!

    Usually mounted on transom corner same side as power cords.
    1989 26' then 1994 32' now 2001 39'

      My direct fresh water hookup is very near the incoming electrical service on the starboard side...

      • All external umbilicals are conveniently located together (electrical, cable and water), minimizes "forgetting" to disconnect something
      • Plenty of room on the inside of the boat for installation purposes (thru-bolting, plumbing, etc)
      • Included a shutoff valve, an inline screen filter and pressure regulator (all serviceable/inspectable by opening the door in the galley to left of frig)
      • Future "whole house" filter system can be accommodated in the same compartment
      • EASY to run a line and tee in AFTER the fresh water pump (located under the galley sole)




      The one disadvantage? Having water supply lines in proximity to electrical panel. However, I felt the advantages (see above) outweighed the negative...

      Fantastic upgrade/addition/improvement in my opinion... no more worrying about running out of water in the middle of a shower, or filling the tank in the middle of dishes!

      The water pressure on my dock is FANTASTICALLY STRONG and I worried that it would stress the plumbing on the boat and create a leak... So, I installed a shut off valve IMMEDIATELY after the external fitting, and a pressure regulator after the valve. I can open the cabinet in the galley and safely shut off city water supply in a snap, and the pressure regulator ensures PSI is never greater than the fresh water pump would create (I admit, have another regulator on the faucet outside).

        On my 47 the inlet is on the transom. It's a PIA sometimes.

        I think by the power inlets would be more serviceable.

        You can get a water inlet with a built in regulator for about 35 bucks.

        The system isn't designed to take 100+ psi.

        Another thing the Bayliner manual for the 47 says to turn off the DC pump when on dock water.

        Others have said they never do and haven't had problems but thats what the MFG says.

          My two cents: Since there are water lines running forward from the wet bar I would follow the same route along the stbd side into the galley sole space and tee into the lines there. An easy place to mount the external fitting would be on the side of the molded stairs to the starboard side deck. I ended up putting a shower there due to the proximity of the hot and cold water of the wet bar and it was easy access. Still pretty simple, an alternative would be to run the water line forward above the stbd fuel tank where there is plenty of room along with the two hot water hoses to the Red Dot heater which would drop the water line into the space below the stairs and then go over to the galley sole space. Either route will keep the water lines low in the boat and away from electronics and other items that might not go well with water

            I installed one on my 3870, I have four recepticals all located aft cabinside starboard, two 30 amp AC's, a cable/phone and then the water. Make sure the water is not above the cable if you have a cable. I took a hose forward to an existing T and shut off just off the pressure side of the pump under the galley sole. Works great. Don't have to follow the Admiral around trying to conserve water at marinas. When you buy a hose, don't bother waiting for the ends to start leaking, just cut them off and replace them with quality brass barbed hose fittings. Don't forget to double clamp at the back of the pressure reducer where the water comes into the boat.

              Here is one on ebay. I have mine mounted on the bottom step in the cockpit behind the transom door. Connect a hose from this to any cold water hose. Mine has a T joint from the sink in the main salon. These are one way valves so when you disconnect and use the on board pressure pump you wont get a flow of water into your cockpit. Hugh
