Rule's LP900S automatic bilge pump is one of our favourite bilge pumps on the market. At just 237mm long and 59mm in diameter, the automatic bilge pump can be mounted either vertically or horizontally and brings power to tight spaces with a pump rate of 56 litres/minute (12.5 gallons/minute). It truly is an excellent choice for small to medium-sized boats, particularly where traditional shaped bilge pumps cannot fit.

The LP900S Rule automatic bilge pump has a fully rotating, multi-directional outlet that swivels as required, with built-in non-return valve to ensure water isn't pumped up through the hose and runs back down into the bilge as soon as the pump stops.

Furthermore, the LP900S has a choice of outlet sizes included in the pack, to suit your existing hose size installation, being 19mm (3/4"), 25mm (1") or 28mm (1 1/8").

Another excellent feature of Rule's LP900S automatic bilge pump is the three operating modes:
High Water Mode: The pump starts when the water level reaches 50mm (2").
Low Water Mode: Turn the motor cartridge by 180 degrees and the sensor is at 33mm (1.3").
Full Electronic Timer Mode: The pump automatically turns on every 2.5 minutes to check for water, if water is detected the pump runs until the water is gone. This mode is particularly beneficial when you want the peace of mind that the pump will check for water every 2.5 minutes, as opposed to waiting until water reaches the magentic sensor.
