Why you need a Float Switch for Bilge Pump

 

So you’ve picked out your bilge pump for your boat and you’re ready to get to work installing it.

Unless you plan on using the pump manually or you’ve picked out an all-in-one automatic bilge pump that has a float switch integrated in the unit, then you’re probably in need of a float switch for the bilge pump.

A float switch is a simple, yet brilliant device, that is used to detect the level of liquid in a confined space.

It consists of a buoyant float attached to a lever that rises and falls with the changing level of liquid present in the area where the switch is placed.

In the context of boats, this is obviously a critical factor as water present within bilges can present a serious issue for boats and boaters.

A smooth and worry-free boating experience is every boater’s intention, however, the unpredictable nature of water and the ocean can present challenges to boaters that demand the need for an automatic sensor to detect excess water build-up onboard any watercraft.

The float switch plays a pivotal role in automating any bilge pump’s operation by providing a clever and affordable solution to the constant need to check for water in bilges.

When a float switch is installed correctly, as water rises in a boat’s bilge, it lifts the float thereby turning on the bilge pump to flow excess water out of the boat.

As the pump does its job, the water level decreases and the float switch returns to a lower level, stopping the pump and avoiding any burnout or overuse.

The extra layer of protection and peace of mind that a float switch provides boaters is unparalleled in the boating world.

They allow boaters to leave boats unattended and obviously are critical to any emergency situation onboard.

In the following list, we have outlined a number of reliable float switches for bilge pumps that are available for boaters easily online.

Join us as we take a stroll through some of the best float switches for bilge pumps available today.

We hope that our research will help you be better prepared when choosing the best float switch for your bilge pump to help protect your treasured vessel!
