                    Description

                    Keeping your bilge clear of nuisance water is the number one objective of Rule Standard Bilge Pumps. Simple as that. Rigorous engineering and testing ensure that Rule keeps delivering pumps that can efficiently handle the highest flow even in the most challenging applications.

                    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.

                    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.

                    Include a vented impeller housing to prevent the pump from becoming airlocked. Removable discharge fittings, straight ports are included and 90-degree ports are also available to suit your installation requirements.

                    Rule Standard Bilge Pumps meet or exceed RoHS, IMCI, CE and ISO standards, and are NMMA listed products.

                    UL listed options can be used on passenger carrying vessels. They are engineered to commercial standards, and offer high pumping capacity and reliability.

                    Rated 5 out of 5 by from Great product. The larger Rule pumps seem to work longer than the smaller ones. I replaced a 10 yr old pump with this one. Easy swap using same strainer mounting.

                    Rated 5 out of 5 by from Rule Pump This pump is for a newer style shower box, I didn't realize that and had to return it, but Defender is easy to deal with when something has to be returned. Great service, thanks guys!!!

                    Rated 5 out of 5 by from Easy to Replace Bilge Pump This purchase was to replace the same brand and size existing bilge pump. It is nice that the wire colors have been kept the same and the pump base is the same. So, the new pump locks into the existing base and the same size hose slides right on. The previous bilge pump came with the boat, so I don't know how long it lasted.

                    I double dog dare you to locate a spec sheet for any rule pump other than the 1500.  Searching on a 2000, 3700 or 4000 spec sheet takes you to the 1500.  This will not help to  identify discharge hose size.
