Factors to consider when buying a bilge pump float switch

The boat size

You should consider your boat’s size and the depth and nature of the waters you are going into. A hand float switch can serve smaller in size boats and go into shallow and less turbulent waters. This switch can comfortably get rid of the water. However, if you are using a bigger boat and going into deeper waters, an electric pump will be well suited. This one is capable of getting rid of large volumes of water.

The installation process

In the market, there are quite a several bilge float switches available. Each of these has its installation process. There are complex switches that require one to hire a professional to do the installation. There are, however, others that are very easy to install, and you can do it yourself. If you do not want to incur the extra costs of hiring a professional, choose the switch that is easier to install to avoid any mistakes. There are those switches that come with an easy to follow manual. This is also one to go for if it comes in a compact design. A best bilge pump float switch is one that can be installed in very few minutes.

The price

We all have different budgets that we work with. There are float switches that cost relatively less, while there are those that will cost you more. Carry out extensive research on the price so that you do not end up spending more than you intended. However, it would help if you parted with more money to get a higher quality switch. This one will serve you for longer as you will not be forced to replace it after only a short while.

The functionality

It is also essential that you carry out a quick study of the functionality of your pump switch. This ensures that depending on the nature of the waters you are going into, the switch will serve you well. For salty waters, select one that is resistant to corrosion and rust. A good one should also be waterproof. That is, it should have a protective feature that protects it against the accumulation of moisture. A great pump is one that has a rigid construction model and can withstand different water types.

Frequently Asked Questions

How to wire a bilge pump float switch?

It is quite easy to wire a bilge pump float switch. Take a close look at the colors of the different wires provided. The brown wire on the pump is usually the wire with a positive charge. Connect this one to one of the gray wire on the float switch. The float switch usually has two gray wires. Take the other gray wire and then connect it to the power supply. Make sure that a fuse protects this power supply. The black wire on the pump has a negative charge. Connect this wire to the negative terminal of the battery.

What is a bilge pump float switch?

A bilge pump float switch is an automatic switch that ensures that your boat remains dry and afloat. There are various types of automatic pump switches, but the float switch is the most common. When water goes into the bilge, it lifts this float, making the pump turn itself on. For the float switch to go back to its normal position, the bilge’s water level has to drop. A bilge pump switch is only effective if it functions as intended. These switches tend to break down after a certain period, which is why it is important to carry out frequent replacements.

How to test a bilge pump float switch?

There are several steps that you should follow to ensure that your bilge float switch works as intended. To check if the pump is working, turn on the helm switch. Make sure that you clean the float switch by removing any materials like dust and other particles. You should also test the battery for enough charge. Please turn it on and check whether all the parts are operating well. There are also other components that you will be required to check. These include the fuse, hose, screen, and impeller. Since a bilge pump switch has many cables, check each one of them for signs of breakage.

How does a bilge pump float switch work?

A bilge pump float switch is a tool that is used by many boat owners to ensure that their boat does not sink due to rising water levels. For this float switch to work, water needs to be present in the bilge. This then causes the float to rise to the water level. The bilge pump then comes on and the boat can remain afloat. A well functioning float switch can detect the rising levels of water in the boat. When the float switch manages to remove all the water from the bilge, it automatically turns itself off.

How to replace a bilge pump switch?

There is nothing that can cost you more than a broken bilge pump float switch. It can either cause the boat top to sink or drain the battery faster than normal. Replacing the bilge pump switch is very easy. Once you have realized that the switch is faulty, turn off the power by removing the cable on the pump from the battery. Detach the switch from the pump carefully, and then check the connection going from the pump’s switch. Cut the wires that are placed above the present connections and then connect back with new wires. You should then attach the switch back to the pump.
