Since bilge pumps need to also work when nobody’s around to activate them, they are fitted with something called a bilge pump float switch. A float switch is essentially a device that is affixed to the bottom of the bilge along with the main pump and cuts and feeds electrical power to the pump. One section of the float switch, often called the shoe because of its shape, is designed to float up as the water level rises inside the bilge. When this portion of the switch floats up it closes an electrical circuit inside the switch that then powers up the pump. The bilge pump will continue pumping water out of the vessel until the level is low enough that the float switch drops and disconnects the electrical current. As you can imagine, in boats that are left in the water unattended for long periods of time, a float switch is as important as the pump itself. Keep in mind that there are some pumps on the market that are designed as automatic pumps. These pumps don’t need to use an external float switch as they have an internal mechanism that switches them on in the presence of water. more

A bilge pump is an absolute necessity in any vessel. A bilge pump is a water pump designed to pump water out of the deepest part of the bilge of a boat. Many small boats for day use can get away with a single electric bilge pump. Larger boats and yachts should be fitted with at least 2 high capacity bilge pumps. One is the primary and the second one is the backup. The backup is usually set to activate only if the primary one has been blocked, breaks or is simply overwhelmed. To be clear, I say 2 pumps are the bare minimum, but if you ask me, I’d recommend more, specially for large expensive boats or those that go far out to sea. Additionally, it is a good idea to have a hand operated bilge pump aboard. In case there is an electrical failure a hand bilge pump can be used to manually pump water out of the boat. It can also be used in case of an emergency if the electric pumps are simply not coping.

Since the most widely used bilge pumps feature a centrifugal impeller, they don’t quite suck up every little bit of water down there. This means, that in most cases you’ll always have a little bit of water at the very bottom of your bilge. To suck up every bit of water in the bilge you’ll need a diaphragm pump. However, the more common centrifugal impeller pumps offer better capacity and have been proven more reliable.

Run the pump's negative terminal cable (black) to a suitable ground. This will usually be a solid metal frame member that also connects to the battery's negative terminal. Connect the positive terminal cable to an electric switch. This switch must be able to handle the current and voltage requirements of the pump, or the switch will burn out very quickly. Most pump switches should be rated to handle at least 110 per cent of the recommended current and voltage of the pump.

Shurflo water pumps are used in a number of applications, and are very popular in the boating industry. Some pumps are designed to handle flooding on board a boat, while others are used to manage the boat's water supply. These pumps are also used on RVs to provide pressure to the water supply system. Shurflo pumps come in a number of sizes and are equipped with different size motors, including 12v and 24v units. [links]

Connect the second switch terminal to the positive terminal of the battery. Use the same size wire throughout the entire circuit.

This bilge pump float switch is made with solid, heavy-duty ABS material and one meter long 18 gauge wires. It is compatible with up to 32-volt bilge pumps. This float switch can automatically turn the bilge pump on when the water reaches a level of 2” and automatically turn the bilge pump off when the water reaches a level of 0.7”. more

This bilge pump float switch can be a bit bigger than people are expecting, so if you’re replacing an old float switch, make sure you pay attention to the measurements of the Rule 40A. It’s a quality pump, but it might be a little difficult to attach to an old mount fitted to an older model. here

Overall, this is one of the best bilge pump float switches because it has a simple design, it is strong and durable, and it is available at an affordable price. This float switch lasts longer and operates just as well as competitor float switches that cost more. more

Bilge pump control switches function similarly to float switches but are very different products from each other. Control switches allow you to control the bilge of your boat from the helm – this is beneficial for bigger boats. [links]
