Drainman Nature Powered Bilge Pump

The Drainman bilge pump runs on nature alone. Wind and waves cause a tug and pull effect on your boat's mooring line. The Drainman uses this energy to pump out water from your bilge. No electricity and no wiring required. This innovative design can pump up to 660 gallons of water per day. It's easy to install, handy to carry, and locks in place.

Features & Benefits:

  • Pump out bilge water without electricity.
  • Powered by nature working with the waves and the wind
  • Vigilantly pumps water overboard while you're away, needing only breeze and wave power
  • No motors to burn out, impellers to damage or drained batteries.

Pump Components

  • Pump with heavy duty straps capable of up to 1 ton of force
  • 10 ft of drain hose
  • Seive and weight for pickup end of hose
  • Requires shackles, snap or lock to secure pump between boat and mooring pendant

Extension hose available

  • For installation requiring a longer hose, a 10 ft extension hose is available
  • Extension hose includes splice fitting to join existing 10 ft.

 

The Drainman is a fully automatic bilge pump, powered by the tug on the moorings created when the boat moves with the wind and waves. The Drainman's capacity is enormous; powered entirely by the movement of the mooring line, it can pump up to 2,500 litres of water per day (550 UK gallons or 660 US gallons per day). The Drainman is made from rugged materials with a tensile strength of up to 10,000 Newton. The Drainman is a reliable companion when you have grown tired of marine covers or of constant bailing.

Easy to Install and Carry

1. The Drainman features two loops, one on either side. One loop is connected to a mooring line by means of a shackle or a snap-hook, the line is then attached to the mooring point, for instance on a jetty. Mooring springs should not be used.

2. The loop on the other side is connected to the boat, using a shackle or a snap-hook, such that the Drainman is attached between the boat and the mooring point. Make sure that the hose and label are facing up when installing, and that the pump is kept above the surface of the water.

3. Place the sieve of the suction hose in the lowest point of the boat (the keelson), where it can easily drain the water. For increased stability, a weight may be placed at the end of the suction sieve loop.

    I've bought it to keep the lazarette dry. The rainwater find it's way there and some water accumulates so when I first saw it, I bought two, one for my boat and another one for my kid's dinghy. It just doesn't work at all. Yes it pumps a few drops of water but not the announced many gallons a day!

          Works well when towing the dinghy to keep it empty and when on the hook. At my the dock there is not enough movement to let it work, but it is well protected.

              This will be great for my boat as nature keeps my bilge dry.
              It's mid-May but the ice is still on the lake as it has been a very late spring here in Alaska.

              This won't work if your boat isn't heavy

              By Aqua

              from East Greenwich RI

              Comments about Drainman Nature Powered Bilge Pump:

              I have an open cockpit Point Jude 15 ft sailboat on a mooring so I thought this product would be great, but it did nothing. between the fact that my boat is light and sits on a quiet anchorage, there wasn't enough pulling power to make the pump work. they need to make this adjustable to different levels of sensitivity.

                    Comments about Drainman Nature Powered Bilge Pump:

                    The Drainman was easy to install, and worked as advertised with enough wind and wave action to operate the pump. Naturally, I have more water in my boat on a rough day, when the drainman performs at its best. I use it whenever I'll be away from the boat for an extended period of time; it offers extra peace of mind, and a backup plan in the event my batteries die and the bilge pumps don't work.

                    What a great idea. This pump kept my 13' Whaler nice and dry while it sat at my dock during the week. The best part is, since it does not run off of power, I didn't have to worry about my battery getting drained, like it had from other "automatic" bilge pumps.

                        This is a great concept. It is very poorly made. Parts are thin plastic with a screw on lid like a water bottle. It worked for a short time and then the lids pulled loose and plastic bellows damaged.
