Bilge Pump Float Switch Wiring Diagram

If you own a boat, then you know how important it is to keep the bilge area free of water. The bilge pump is used to remove any water that enters this area, and the float switch is what activates the bilge pump when water reaches a certain level. In this article, we will be discussing the wiring diagram for a bilge pump float switch.

What is a Bilge Pump Float Switch?

A bilge pump float switch is a device that activates the bilge pump when water reaches a certain level in the bilge area of a boat. The switch is a mechanical device that is activated by the weight of water in the bilge area. When the water reaches a certain level, the switch is triggered and the bilge pump is turned on to remove the water.

There are two types of bilge pump float switches – the manual switch and the automatic switch. The manual switch requires the operator to turn on the pump manually, while the automatic switch is activated automatically when water reaches a certain level.

Wiring Diagram for Bilge Pump Float Switch

When it comes to wiring a bilge pump float switch, the process is fairly simple. The switch itself has three wires – a positive wire, a negative wire, and a wire that connects to the pump. The pump also has a positive wire and a negative wire. The wiring diagram for a bilge pump float switch is as follows:

Bilge Pump Float Switch Bilge Pump
Positive wire Positive wire
Negative wire Negative wire
Wire that connects to pump

The wire that connects to the pump should be connected to the positive wire of the pump. The negative wire of the pump should be connected to the negative wire of the battery. The positive wire of the battery should be connected to the positive wire of the float switch, and the negative wire of the battery should be connected to the negative wire of the float switch.

FAQs

What should I do if my bilge pump float switch isn’t working?

If your bilge pump float switch isn’t working, there are a few things you can check. First, make sure that the switch is properly connected to the pump and the battery. If everything is connected correctly, then you may need to replace the switch.

What size bilge pump should I use?

The size of the bilge pump you need will depend on the size of your boat and the amount of water that typically enters the bilge area. It is always better to go with a larger pump than a smaller one, as this will ensure that the pump can handle any amount of water that enters the bilge area.

Can I install a bilge pump float switch myself?

Yes, you can install a bilge pump float switch yourself, as long as you have some basic knowledge of electrical wiring. However, if you are not comfortable working with electrical wiring, it is always best to have a professional do the installation for you.

How often should I test my bilge pump float switch?

You should test your bilge pump float switch at least once a month to ensure that it is working properly. To test the switch, simply fill the bilge area with water and make sure that the pump turns on when the water reaches the appropriate level.

What is the life expectancy of a bilge pump float switch?

The life expectancy of a bilge pump float switch will vary depending on the brand and model, as well as how often it is used. However, most switches should last between 3-5 years with regular use.

Conclusion

The bilge pump float switch is an important component of any boat’s bilge system, as it ensures that any water that enters the bilge area is promptly removed. By following the wiring diagram provided in this article, you can easily install a bilge pump float switch yourself and ensure that your boat is always protected from flooding.
