Rated at 800 GPH nominal flow, the system pairs a high-capacity 12V DC pump with a sealed polycarbonate shower box that resists unwanted water splash while remaining fully serviceable without special tools. A back flow prevention feature reduces the amount of water that can siphon back into the shower box, protecting against re-flooding once the pump shuts off. The unit uses a fast fix mounting system and threaded port fittings for straightforward installation, and it is built to Rule's testing standards for automatic operation in demanding marine environments. This makes the Rule 98B suitable for boat owners replacing a worn-out shower or sink drain pump, or for new shower\/sink drain installations where reliable, hands-off water removal is required. The pump draws 2.9 amps at 12V (3.5 amps at 13.6V) and is protected by a 5 amp fuse, with a 3\/4 inch discharge hose connection for compatibility with standard marine hose. The system measures 10.24 inches long by 9.5 inches wide by 5.5 inches high and is constructed of durable plastic components.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Rule\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 98B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Flow Rate:\u003c\/strong\u003e 800 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmp Draw:\u003c\/strong\u003e 2.9 Amps at 12V, 3.5 Amps at 13.6V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Fuse Size:\u003c\/strong\u003e 5 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge Hose Diameter:\u003c\/strong\u003e 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLid Type:\u003c\/strong\u003e Sealed polycarbonate lid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Clear or Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 10.24 inches L x 9.5 inches W x 5.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack Flow Prevention:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the flow rate of the Rule 98B Shower Drain System?\u003c\/strong\u003e The Rule 98B has a nominal flow rate of 800 GPH, providing high-capacity removal of shower and sink grey water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage does this shower drain system use?\u003c\/strong\u003e The Rule 98B operates on 12 VDC, drawing 2.9 amps at 12V and 3.5 amps at 13.6V.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat fuse size is recommended for the Rule 98B?\u003c\/strong\u003e A 5 amp fuse is recommended for the Rule 98B Shower Drain System.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Rule 98B include back flow prevention?\u003c\/strong\u003e Yes, the Rule 98B Shower Drain System is equipped with back flow prevention to reduce water siphoning back into the shower box.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size discharge hose does the Rule 98B use?\u003c\/strong\u003e The Rule 98B has a 3\/4 inch discharge hose diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Rule 98B shower box made from?\u003c\/strong\u003e The Rule 98B shower box lid is a sealed polycarbonate lid, with the overall unit constructed of plastic components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Rule 98B Shower Drain System?\u003c\/strong\u003e The Rule 98B is available in a clear or neutral color.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Rule 98B weigh?\u003c\/strong\u003e The Rule 98B Shower Drain System weighs 3.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Rule 98B?\u003c\/strong\u003e The Rule 98B measures 10.24 inches long by 9.5 inches wide by 5.5 inches high.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Rule 98B easy to install?\u003c\/strong\u003e Yes, the Rule 98B uses a fast fix mounting system with threaded port fittings for simple installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Rule 98B be serviced without special tools?\u003c\/strong\u003e Yes, the Rule 98B shower box has a clip-on lid designed to be fully serviceable without the need for any tools.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Rule 98B fully automatic?\u003c\/strong\u003e Yes, the Rule 98B Shower Drain System is designed for fully automatic operation.\u003c\/p\u003e","brand":"Rule","offers":[{"title":"Default Title","offer_id":49028302078171,"sku":"RUL-98B","price":176.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Rule-Shower-Pump-System-New__30718.1737897406.500.750.jpg?v=1785165440","url":"https:\/\/www.goodvibesmarina.com\/products\/rule-98b-800-gph-shower-drain-system-12v-dc-automatic-pump-with-back-flow-prevention","provider":"Good Vibes Marina","version":"1.0","type":"link"}
