Keep the bilge dry with a pump built to switch on the moment water rises

An automatic bilge pump has a built-in electronic or float-type sensor that detects rising water inside its housing. Once the level reaches the trigger point, the pump switches itself on without any input from you, and switches off again once the water has cleared — that's what makes it "automatic" rather than a plain manual pump you have to operate yourself.

Yes — it's an automatic pump that activates as water rises past its internal sensor, rather than needing a separate float switch wired in.

No — the automatic sensing is built into the pump itself, so you don't need to wire in a separate float switch for basic operation. Some installations add one anyway as a backup or high-water alarm, but it isn't required for the pump to work.

Bilge pump current draw varies by GPH rating — check the manufacturer's spec plate for this model and fuse the circuit above the stated figure, wiring it as directly to the battery as possible.

It's rated at 1100 GPH, which is enough to keep ahead of a slow leak, condensation runoff or wash-down water rather than just keeping pace with it.

Yes — automatic bilge pumps like this one are designed to sit in place permanently, wired live to the battery so they can respond the moment water starts to rise, rather than being connected only when needed.

It uses a low-profile housing, so it sits flatter than a standard cartridge-style bilge pump, which helps where clearance under a bunk, locker or floor panel is limited.

Automatic bilge pumps of this type are generally built to tolerate brief dry running once the water level drops below the sensor, but check the manufacturer's guidance for continuous dry-run limits.

Pour a small amount of water into the housing until it reaches the sensor's trigger level and confirm the pump switches on and clears it, then switches off again once dry. Testing periodically, especially before a trip, is the only way to know it will actually work the one time you need it.

It runs from a 12V supply through an inline fuse, typically wired directly to the leisure or start battery so it can operate even when other systems are switched off.
