Jabsco-Rule 500 GPH Standard 12V Bilge Pump

Jabsco-Rule 500 GPH Standard 12V Bilge Pump

With over 50 years of excellence Jabsco-Rule provides superb pumping performance. Helps keep your bilge clear of water. Going through rigorous engineering and testing bring flow efficiency in even the toughest conditions.

• Threaded Discharge - provides easy install and maintenance
• Back Flow Prevention - reduces odor and helps keep bilge clean by reducing leftover water in the bilge
• High Flow - provides better flow at consistent amperage through impeller optimization
• Hidden Air Vents in the body - Helps with the check valve and preventing locking during plumbing installations
• Built-in Thermal Cut-Off - bestows extra protection for the pump and vessel

Specifications:

• Flow Rate: 500 Gallons Per Hour (GPH)
• Voltage : 12 VDC
• Fuze Size: 4 Amp
• Amp Draw: 2.7
• Height: 3-7/8"
• Width: 2-7/8"
• Port Type: 3/4" Hose Barb

Installation Information:

• Before installing or servicing the pump disconnect the power
• Use stainless steel hose clamps to attach the discharge hose to the hose barb
• Discharge houses for thru-hulls should be at least 8" above the water line
• Check valves should not be used to prevent siphoning into the boat
• A check valve should only be used to prevent the cycling of an automatic bilge pump from backflow of the discharge line  

Installation Instructions:

• Remove pump from the base by using the push tabs located on the side of the pump
• After inserting the pump into the base push down until an audible sound is heard.
• *Stainless Steel Flathead screws of an appropriate length is recommended to secure the pump but not penetrate the hull. Ensure water is unable to penetrate the screw holes.

Issues that can reduce the flow of a bilge pump:

• Length of discharge pipe
• Number of bends
• smoothness vs. roughness of pipe/fitting interior

Frequently Asked Questions

What is the Jabsco-Rule 500 GPH Standard 12V Bilge Pump used for?

The Jabsco-Rule 500 GPH Standard 12V Bilge Pump is designed to help remove water from a boat's bilge. It delivers a flow rate of 500 GPH from a 12 VDC power supply and uses a 3/4" hose barb discharge port. Its optimized impeller design is intended to provide consistent flow at its specified amperage.

What are the electrical specifications of the Jabsco-Rule 500 GPH Bilge Pump?

The Jabsco-Rule 500 GPH Bilge Pump operates at 12 VDC with a 2.7 amp draw and requires a 4 amp fuse. Before installing or servicing the pump, disconnect the power. Verify that the vessel's electrical system and fuse setup are appropriate for these specifications.

What features help the Jabsco-Rule 500 GPH Bilge Pump manage water and backflow?

This bilge pump features backflow prevention to reduce leftover water in the bilge and help reduce odor. Hidden air vents in the pump body assist with the check valve and help prevent locking during plumbing installations. A built-in thermal cut-off also provides additional protection for the pump and vessel.

How do you install the Jabsco-Rule 500 GPH Standard 12V Bilge Pump?

Remove the pump from its base using the push tabs on the sides. After placing the pump into the base, push it down until an audible sound is heard. Use stainless steel hose clamps to secure the discharge hose to the 3/4" hose barb, and use appropriately sized stainless steel flathead screws to secure the base without penetrating the hull.

What can reduce the flow rate of the Jabsco-Rule 500 GPH Bilge Pump?

Several plumbing factors can reduce bilge pump flow, including the length of the discharge pipe, the number of bends, and the smoothness or roughness of the pipe and fitting interiors. For thru-hull discharge hoses, the installation information specifies that the discharge hose should be at least 8 inches above the water line.

Should a check valve be used with the Jabsco-Rule 500 GPH Bilge Pump?

Check valves should not be used to prevent siphoning into the boat. According to the installation information, a check valve should only be used to prevent an automatic bilge pump from cycling due to backflow from the discharge line.
