It is the 750 GPH version in Attwood's larger sump box format, which makes it a practical fit when one box needs to manage more than a single drain.\u003c\/p\u003e\u003cp\u003eThe box measures 13 inches long, 7-3\/8 inches wide, and 4-7\/16 inches high. It accepts 3\/4 inch, 1 inch, 1-1\/8 inch, and 1-1\/2 inch inlet hose sizes, and the outlet is sized for 3\/4 inch I.D. hose. That helps when a boat uses different drain hose sizes between a shower stall, head sink, and galley sink.\u003c\/p\u003e\u003cp\u003eThe top lifts off for filter access, the lid gasket helps keep the box sealed at the top, and the built-in air vent helps reduce the air-lock problems that can interrupt sump discharge underway or at the dock.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e12V shower sump system with Packard connector\u003c\/li\u003e\n\u003cli\u003e750 GPH multi-port sump in the larger box size\u003c\/li\u003e\n\u003cli\u003e3\/4 inch I.D. outlet connection\u003c\/li\u003e\n\u003cli\u003eInlet options for 3\/4 inch, 1 inch, 1-1\/8 inch, and 1-1\/2 inch hose\u003c\/li\u003e\n\u003cli\u003eMulti-port layout for tying in more than one drain\u003c\/li\u003e\n\u003cli\u003eAir vent built into the box to help prevent air lock\u003c\/li\u003e\n\u003cli\u003eSnap-off lid with removable filter access for routine cleaning\u003c\/li\u003e\n\u003cli\u003eBox size of 13 inches x 7-3\/8 inches x 4-7\/16 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eThis sump needs to sit lower than the shower drain and any other drain lines feeding it. For steady pump-out, the outlet hose should rise continuously from the box to the thru-hull without low spots, and the inlet hoses should rise smoothly from the sump toward their drains. Those routing details matter on boats where hose runs have to pass around stringers, tankage, or liners.\u003c\/p\u003e\u003cp\u003eThe larger box footprint is worth checking before replacement on compact bilge or utility spaces. Leave enough side access to release the lid tabs and enough clearance above the box to remove the cover and clean the filter without having to pull the whole unit back out.\u003c\/p\u003e\u003ch6\u003eElectrical and system fit\u003c\/h6\u003e\u003cp\u003eThis version is for 12V DC systems only. The Packard connector is one of the main fit points to confirm before ordering, especially when replacing an existing shower sump on a production boat where the factory harness is already terminated for that plug style.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis layout makes sense for cruisers, express boats, and small yachts where one serviceable sump box is used to collect shower water and secondary sink drains in the same part of the hull. It is also a sensible match when easy filter access matters because the box will need periodic cleaning from hair, soap residue, and everyday gray-water debris.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e4143PF1\u003c\/span\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":53721529614517,"sku":"QBP921113","price":153.72,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1322197_qbp921113.webp?v=1794116687"},{"product_id":"qbp356090","title":"Attwood Marine Sahara-Powered Shower Sump System, 500 GPH, 12V","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Attwood Marine 4141-1 is a 12V shower sump system with a 500 GPH automatic pump for moving gray water from a shower pan and other onboard drains. It uses a standard-size sump box, a 3\/4-inch I.D. outlet, and 36-inch wire leads, which makes it a practical fit for many small to mid-size boat plumbing layouts.\u003c\/p\u003e\u003cp\u003eThis sump is built for installations where shower water needs to be collected, filtered, and discharged reliably instead of draining straight into the bilge. Multiple inlets can be connected to more than one drain with different hose sizes, so it works well when the shower shares the sump with nearby sink or compartment drains.\u003c\/p\u003e\u003cp\u003eThe box has a clear top for quick filter checks, a gasketed lid to help contain overflow, and an air vent to reduce the chance of air lock.

The discharge hose should rise smoothly from the sump to the thru-hull without dips, because low spots in the hose can trap air and reduce pump performance.\u003c\/p\u003e\u003cp\u003eFor boats with more than one gray-water source, the inlet layout gives some flexibility when routing hoses into the box. The lid removes for service, so it is worth leaving enough clearance around the sump to open the top and clean the filter without pulling the whole unit back out.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis sump is a good match for 12V boats that need a compact gray-water collection point for a shower or a shower shared with one or more nearby drains. It fits best where the plumbing run can keep the outlet hose rising toward the discharge point and where routine access to the filter is still possible after installation.\u003c\/p\u003e\u003cp\u003eFor owners replacing an older sump box, the details that matter most are system voltage, outlet hose size, available mounting space, and whether a standard-size box matches the footprint already in the boat. Checking those points before ordering usually tells you very quickly whether this is the right replacement.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eThe filter should be checked and cleaned as part of normal onboard plumbing maintenance, especially on boats that see frequent shower use or pick up hair, soap residue, and other debris in the drain line. The clear lid helps with quick inspections, which makes it easier to catch buildup before it slows the pump or causes the sump to cycle more often than it should.\u003c\/p\u003e\u003cp\u003eIf the boat is laid up in cold weather, the sump and connected hoses should be drained as part of winterization. Keeping the box clean and the hoses clear will do more for long-term performance than any extra add-ons.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003e4141-1\u003c\/span\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":53721582370997,"sku":"QBP356090","price":231.42,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1322140_qbp356090.jpg?v=1794118799"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/collections\/8ef28c21-735e-502d-8894-d3b97e0312b1.webp?v=1794118099","url":"https:\/\/www.qualityboatparts.com\/collections\/cat-freshwater-systems.oembed","provider":"Quality Boat Parts","version":"1.0","type":"link"}
