Installing a Bilge Pump by Don Casey - Boat. TECHby Don Casey. Revised by Boat. US editors in April 2. Bilge pump installation is straightforward, but it is essential not to overlook key details. Mount the pump. You must not place the pump in the bilge unrestrained. If it falls over it will suck air and burn out. Pumps must be fastened down.
How to Wire a Bilge Pump. Designed to remove bilge water, the bilge pump is an indispensable part of any boat, yacht or sailing vessel. The installation of this pump. Standard Bilge Pump Instruction Manual Standard Bilge Pump Instruction Manual 8 Disconnect power from the system before working on the unit to avoid personal injury, damage to the surrounding environment and/or damage to the unit. A bilge pump is a water pump used to remove bilge water. Since fuel can be present in the bilge, electric bilge pumps are designed to not cause sparks. Electric bilge pumps are often fitted with float switches which turn on. Tsunami Bilge Pump 4606, 4608, 4612, 4613 Series Installation Instructions SAVE THESE INSTRUCTIONS Form Number 69390 Rev.

Brackets are available that attach to a stringer or other vertical feature, or you can epoxy a couple of bolts to the bottom of the bilge to serve as mounting studs. Float switches must also be fastened. Use smooth- bore hose. Corrugated hose reduces pump output by as much as 3. Bends and long runs also reduce pump output, so make the hose run as straight and as short as possible. That may mean discharging the pump through the side of the hull rather than through the transom. However. . . Place the discharge above the waterline.
If the discharge is submerged when the pump runs, the ocean siphons back through the pump into the bilge when the pump shuts off. When enough water has entered to float the switch, the pump will eject it, only to have it siphon back again. This continues until the battery is depleted, then the water floods the boat until it reaches a level that gets the crew's attention. The discharge fitting must never go below the waterline. If the fitting is through the transom, be sure it is high enough not to submerge when the stern squats.
And if it is through the side of the hull, it must be high enough to remain above the water at the deepest angle of heel. Use a thin- wall fitting. The through- hull fitting can further reduce pump capacity. To minimize this restriction, use a fitting with the largest possible opening.
Lead wiring up. It is essential to get the pump wiring out of the bilge as quickly as possible. Run the wires up and secure them so that they do not sag into the bilge water. Don't skimp on wire size. A 3,5. 00 gph pump will draw 1. Consult the ABYC Wire Size Table to determine the appropriate wire for your pump and length of wire run. Use butt connectors and heat shrink. Crimp- on step- down butt connectors will assure a good mechanical and electrical connection between the supply wires and the pump leads.
Enclose these connections in adhesive heat shrink tubing to make them water tight. You must slide the heat shrink over the wire and out of the way before you make the connections. Then center the tubing over the crimped connector and shrink it with a heat gun or by playing a flame beneath it. Be sure there are no explosive fumes in the bilge!
Connect to the battery. When you turn the power off to leave the boat unattended, you don't want to turn off the bilge pump. Connect an automatic bilge pump directly to the battery, not through the distribution panel.
Fuse the positive side. It is essential to have a fuse in the positive wire as close to the battery as possible. Some switch panels (see below) include a fuse. Otherwise join an in- line fuse holder to the battery end of the positive wire using a crimp butt connector.
Install terminal fittings. Do not strip the ends of the supply wires and loop them beneath the battery terminal wing nuts. Install crimp- on ring terminals the proper size to fit the threaded posts on your battery. Use a copper washer- not steel- between the wing nut and the ring terminal. Three- way switch. If your bilge pump has a separate float switch, you may want to wire it to a three way switch that allows you to select automatic, on, or off.
Be sure to support all wire runs at least every 1. Two pumps. A bilge pump big enough to deal with a real emergency will do a poor job of keeping the bilge dry because the water in the discharge hose drains back into the bilge when the pump shuts off. And a big pump requires a big hose.
The ideal bilge pump arrangement is a small (4. Stepping the discharge hose from the small pump down to 1/2- inch minimizes the backflow from the hose when the pump cycles, maintaining a dryer bilge. The large pump can be wired to a float switch if you prefer, but I think a manual switch makes more sense. An added advantage of this bilge pump configuration is that the high- capacity pump sits high and dry, extending its life indefinitely.
