Rule 24DA 360 Series Submersible Bilge Pump With 35A Float Switch - 1362 LPH

This Rule kit combines a 12V 24DA 360 GPH submersible bilge pump with a 35A Rule-A-Matic float switch, providing automatic bilge-water removal when correctly wired and fused.

The kit pairs Rule’s compact 24DA standard bilge pump with the Rule 35A mercury-free float switch. The pump itself is non-automatic; the 35A switch closes the circuit as the water level rises and opens it after the water level falls, creating a conventional automatic bilge-pump system.

What Is the Rule 24DA and 35A Bilge Pump Kit Used For?

This kit is used to install an automatic 12V bilge-pumping system in smaller craft and confined bilge spaces. The 360 GPH pump removes nuisance water, while the float switch provides automatic on/off control.

What Is Included?

• One Rule 24DA 360 GPH submersible bilge pump
• One Rule 35A Rule-A-Matic float switch

What Is Not Included?

• Discharge hose, through-hull fitting and hose clips
• Panel switch
• Correctly rated fuse, cable extensions and waterproof connectors
• Installation fasteners unless present in the retail package

Which Boats and Bilge Systems Is This Kit Suitable For?

• For 12V DC marine electrical systems.
• Pump connects to 19 mm (3/4 in) ID discharge hose.
• 35A switch is rated up to 14A at 12V; the included 24DA pump draws substantially less than this limit.
• Suitable for conventional automatic control; an optional 12V three-way panel switch may be added for automatic/off/manual control.

How Do the Pump and Float Switch Work Together?

The 24DA pump provides the water-removal flow, while the 35A float switch opens and closes the pump circuit as the bilge-water level rises and falls. The pump is not independently automatic; automatic operation depends on correct float-switch installation and wiring.

How Do I Confirm This Kit Is Suitable?

Check the electrical system, available bilge space, discharge route and switching capacity before installation:

• System voltage: 12V DC
• Pump rated open flow: 360 GPH (1,363 LPH; approx. 23 litres/minute)
• Discharge hose: 19 mm (3/4 in)
• Float-switch maximum current: 14A at 12V DC
• Pump ON level: Approx. 51 mm (2 in)
• Pump OFF level: Approx. 19 mm (3/4 in)

Construction and Design

• Backflow prevention: Yes
• Thermal protection: Built-in thermal cut-off
• Ignition protection: Yes
• Standards: CE; ISO 8849 marine bilge-pump standard
• Mounting base: Removable for cleaning and servicing

Installation and Safety

Mount the pump at the lowest practical point of the bilge and install the float switch nearby on a level surface where it can move freely. The pump and switch must be wired through the specified fuse using marine-grade cable and waterproof connections positioned above the maximum bilge-water level. Test switch movement and pump operation after installation and at regular service intervals.

Maintenance

Inspect and test the complete bilge-pump system regularly and before extended passages. Reduced flow, repeated fuse failure, unusual noise or slow switching requires investigation before the vessel is used.

• Remove debris from the strainer and impeller area.
• Inspect the discharge hose, clips, through-hull and anti-siphon arrangement.
• Check the wiring, fuse, terminals and control switch for heat, corrosion or damage.
• Keep the automatic sensor or float-switch movement clear of oil, dirt and debris.
• Test manual and automatic operation after cleaning or service.
• Replace damaged components rather than operating an unreliable bilge system.

• 360 GPH (1,363 LPH) nominal open-flow pump capacity
• 12V DC operation
• 19 mm (3/4 in) discharge connection
• Pump includes thermal cut-off and easy-clean strainer
• 35A switch is mercury-free, ignition protected and serviceable from its removable base

Frequently Asked Questions

Is the Rule 24DA pump automatic by itself?
No. Automatic control is provided by wiring the included Rule 35A float switch into the pump circuit.

What hose size is required?
Use 19 mm (3/4 in) ID bilge hose and secure it with suitable marine-grade hose clips.

Does the kit include a panel switch?
No. A compatible 12V panel switch can be added separately where manual override is required.

What fuse should be used?
Use the pump manufacturer’s recommended 4A fuse and follow the installation diagram. The float switch rating is a maximum switching capacity, not the required fuse size.

Specifications

Flow ratings are nominal open-flow figures. Installed output will reduce as discharge head, hose length, bends, restrictions and supply-voltage loss increase.
