{"product_id":"qbp678572","title":"Jabsco PAR-Max 4 Electric Toilet Rinse Pump, For 37245\/37255\/37275 Toilets, 4 GPM","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Jabsco PAR-MAX 4 is an electric toilet rinse pump for supplying flush water to compatible Jabsco marine toilet systems. It is used as the rinse pump on Jabsco 37245, 37255, and 37275 series toilets, helping deliver water to the bowl during the flushing cycle.\u003c\/p\u003e\u003cp\u003eThis pump is available in 12V and 24V versions to match the vessel’s DC system. Both versions deliver up to 16.3 litres per minute, equal to 4.0 GPM, and self-prime up to 3.0 m, which is useful when the pump is mounted away from the toilet or above the waterline within the limits of the installation.\u003c\/p\u003e\u003cp\u003eThe dry-run capability helps protect the pump if the intake supply is interrupted for a short period. It is a practical replacement part for onboard sanitation systems where voltage matching, flow rate, and toilet-series compatibility matter before purchase.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eElectric rinse pump for Jabsco 37245, 37255, and 37275 series marine toilets.\u003c\/li\u003e\n\u003cli\u003eAvailable in 12V DC and 24V DC versions for matching the boat’s electrical system.\u003c\/li\u003e\n\u003cli\u003eDelivers up to 16.3 LPM, or 4.0 GPM, for toilet bowl rinse water during flushing.\u003c\/li\u003e\n\u003cli\u003eSelf-primes up to 3.0 m, giving more flexibility when placing the pump near the toilet or intake line.\u003c\/li\u003e\n\u003cli\u003eCan run dry without damage, helping protect the pump if water supply is briefly interrupted.\u003c\/li\u003e\n\u003cli\u003e12V version draws 7.0A and uses a 15A fuse; 24V version draws 4.0A and uses a 10A fuse.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product is offered in two voltage configurations so it can be matched to the vessel’s DC supply.\u003c\/p\u003e\u003cp\u003eThe voltage is the key difference between the variants.

It is commonly used when replacing the rinse pump in a quiet-flush style installation where a dedicated pump supplies water to the toilet bowl.\u003c\/p\u003e\u003cp\u003eBefore installation, the existing toilet series and vessel voltage should be checked. A 12V pump should not be fitted to a 24V supply, and a 24V pump should not be fitted to a 12V supply.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe pump should be installed in a dry, accessible location where the inlet strainer, hose connections, and wiring can be inspected later. Keeping the pump close to the toilet helps reduce plumbing length and supports steady rinse-water delivery.\u003c\/p\u003e\u003cp\u003eAs with any marine sanitation pump, hose runs should be secure, wiring should be protected from moisture and vibration, and the correct fuse size should be used for the selected voltage version. This is a good match for boat owners maintaining an existing Jabsco electric toilet rather than changing the full toilet assembly.\u003c\/p\u003e","brand":"Jabsco","offers":[{"title":"12V","offer_id":52581863030965,"sku":"QBP678572-V1","price":254.99,"currency_code":"USD","in_stock":false},{"title":"24V","offer_id":52581863063733,"sku":"QBP678572-V2","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334432_qbp678572.jpg?v=1780200846","url":"https:\/\/www.qualityboatparts.com\/products\/qbp678572","provider":"Quality Boat Parts","version":"1.0","type":"link"}
