The addition of a float switch to a bilge pump circuit allows the bilge pump to come on automatically once the water in the boat reaches a certain level. This ensures that even if there is nobody on the boat to turn on the bilge pump, it will still pump water out of the boat.
Should a bilge pump be fused?
Motor loads such as your bilge pump should be fused at no more than 150% of the full load amps of the motor when running (full load amps are listed on a plate or sticker on any electrical device).
Do all bilge pumps have a float switch?
Most pumps have an automatic float switch that detects when water is in the bilge, and automatically turns on the pump. Small amounts of water in the bilge are normal, so don’t sweat it if you see a little puddle in the bilge. But any more than an inch or two could be a problem.
What size fuse do you need for a bilge pump?
Verify that the standard 15 amp fuse installed in the panel is appropriate for both the circuit wire and the bilge pump. Remove and replace with the bilge pump manufacturers recommended fuse size (20 amp maximum).
How to wire a bilge pump?
Mount the bilge pump securely in the bilge. Unrestrained bilge pumps can fall over, intake air and become damaged.
How do you get to bilge pump?
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. 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.
What is the purpose of a bilge pump on a boat?
The bilge is the lowest inner part, or bottom point, on a boat, and is designed to collect excess water. On vessels of virtually any size, a pump inside the bilge performs a very important function: to remove accumulated water by creating pressure or suction so that the water can be removed.
Does livewell drain into bilge?
For livewells you should have two hoses. Starting in your bilge area you’ll see the supply hose. It will be connected to a livewell pump (same as your bilge pump) There will also be a return (drain) hose from the livewell with a valve on it. In no circumstances does your livewell drain to your bilge.
