Rule 14A Back Flow Prevention
Keeping your bilge clear of nuisance water is the number one objective of our Rule Standard Bilge Pumps. Simple as that. Rigorous engineering and testing ensure that we keep delivering pumps that can efficiently handle the highest flow even in the most challenging applications. Rule Standard Bilge Pumps are standalone products with switches sold separately. The pumps can be paired with a float or panel switch, providing an extra level of security and protection. Our Standard Bilge Pumps are engineered with snap-lock strainer bases allowing for easy access to clean the strainer and impeller cavity. They also feature a non-return valve that prevents water left in the discharge from running back, keeping bilges dryer and cleaner. Rule Standard Bilge Pumps features a vented impeller housing to prevent the pump from becoming airlocked. Removable discharge fittings, including straight or 90-degree ports are available to suit your installation requirements as well.
