    Washdown pump instalation ?-gctid367407

    I have a 3288 MY. I am going to install the pump down in the cave. I would like to use the thru hull line that feeds the head. I will place a tee in the line but need to know if I require some kind of valve (backwater valve ?) on the head side of the line ?????? Any kind of info would be appreciated.

      Mine is located in the cave however I had to add a second through hull because it would suck air through the toilet.

      The routing that I used was behind the trim above the medicine cabinet in the head. I used ridged plastic from the anchor locker to the helm bulkhead

        I have my washdown pump tee'd off the head supply line. My wash-down hose connection has it's own check valve, and the electric pump for the toilet does also. If yours sucks air from either side, just install check valves. They're one-way valves that only allow water to go one direction. Standard hardware store item.

        On my former 305, I had a hose outlet in the cockpit and one on the bow, difficult, but not impossible to route. On my current 2858, the outlet is in the cockpit, where I use a 10' hose and nozzle. I just add a hose for cleaning the bow. Maybe someday I'll run a line to an outlet forward...

          I did not install any check valves and have had no issue. I have a Raritan Sea Era head with a seperate water pump.

          Jeff it turns out there is a large open PVC conduit that runs front to back in the 305 under the galley. It runs from the mid cabin mechanical space to the forward berth. I used this to run my tubing forward.

            That's exactly where I ran it Jim. I haven't poked around in the belly of the 2858 yet, so I'll just need that longer hose. Maybe next year...

              I installed a wash down pump on our 3288 a couple of years ago. Our pump is mounted inside the v-berth hanging locker and picks up from the toilet through a check valve. The water line is run up the starboard side along the hull and deck joint and goes directly into the foredeck storage locker where there is a hose bib and seperate switch to turn the pump on and off from the deck. The wiring is layed with the hose on the interior deck/hull joint. By locating the pump close to the source and close to the hose you will be much happier with the pressure you can develop. Ours works great for blasting off the chain as we are retrieving dirty ground tackle. Be sure and place your check valve between the pump and the toilet to avoid sucking air.

              Good luck, it is a nice upgrade and having the hose neatly tucked into the large foredeck locker is great!
