Open a tap and it runs, close it and it stops. Built-in thermal protection lets it run dry without damage, and the internal by-pass keeps water flowing smooth instead of pulsing.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Shurflo Revolution 4008-101-E65 is a 12-volt automatic demand fresh water pump built for the boats and RVs where the water system just needs to work, trip after trip. It pushes 3 gallons per minute and shuts off at 55 PSI, so you get strong, steady pressure at the galley tap, the head, and the shower without babying it. Turn on a faucet and it runs. Close it and it stops. That's the whole idea behind a demand pump, and this one does it quietly.\u003c\/p\u003e\n\u003cp\u003eHere's what makes the demand design nice to live with. The pump senses the drop in line pressure the moment you open a fixture, kicks on, and holds pressure while water's flowing. When you shut the tap, pressure climbs back to 55 PSI and the internal pressure switch cuts power. The built-in internal by-pass smooths out that on-off behavior, so you get less of the rapid cycling and pulsing you feel with cheaper pumps at low flow. Crack a faucet just a little and the water still comes out even, not in bursts.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward if you plan the mounting and the wiring. We like to mount it vertically with the ports facing down on a set of rubber pads or the factory-style feet. That keeps vibration and noise out of the hull or the RV floor, which matters a lot on a quiet night at anchor. The two 1\/2 inch NPMS male ports take standard threaded fittings, and a little thread sealant tape on those threads goes a long way toward a dry install. For the power side, run at least 14 AWG wire on any run longer than about 8 feet. Undersized wire causes voltage drop, and voltage drop makes the pressure switch chatter. Fuse it and you're set.\u003c\/p\u003e\n\u003cp\u003eThis pump ships without a strainer, so add an inline strainer on the inlet side before it sees any water. It's cheap insurance. The Revolution is rated to run dry without damage thanks to built-in thermal protection, but a strainer keeps sand, tank flakes, and debris out of the valves, and that's what actually wears out a diaphragm pump over the long haul. If the thermal cutout ever trips during a long continuous draw, just give it time to cool and it resets on its own.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Boaters and RV owners who want a reliable single-outlet or light multi-outlet fresh water system. It's a great fit for center consoles running a washdown, cruisers and sailboats feeding a galley and a head, and travel trailers where you want real household-feeling pressure. At 3 GPM it's happiest serving one fixture at a time at full flow. If you routinely run two outlets wide open at once on a bigger boat, you'll want to step up in flow. And if you deal with short-cycling on a longer plumbing run, adding a small accumulator tank downstream evens out the pressure and cuts down on how often the pump clicks on and off.\u003c\/p\u003e\n\u003cp\u003eAt 8.1 inches long, 4.9 inches wide, and 4.3 inches tall, it tucks into most pump bays and under-sink lockers without a fight. It's a proven design from Shurflo by Pentair, a name that's been under the sole of marine and RV water systems for years. Wire it right, strain the inlet, and this is the kind of pump you forget about because it just keeps delivering water.\u003c\/p\u003e\n\u003cp\u003eA little seasonal care keeps it happy. Before winter layup, drain the system and run the pump briefly to clear the head so nothing freezes and cracks a fitting. In hard liveaboard use, an annual fresh water flush keeps the internal by-pass valve moving freely, since that valve can get sticky after a year or two of daily cycling. None of this is heavy wrenching. It's the same basic care any pressurized water system on a boat or coach wants.\u003c\/p\u003e\n\u003cp\u003eWhat you feel at the tap is the real story. Steady 55 PSI means a shower that actually rinses, dishes that get done without you standing there waiting, and a head that flushes with authority. The 3 GPM flow is well matched to that pressure, so you're not fighting a weak stream or a pump that can't keep up. It's an honest, mid-size fresh water pump that does exactly what it says on the box, and that's high praise for a part you never want to think about once it's installed.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e3 GPM flow rate delivers strong, steady water at the galley, head, and shower\u003c\/li\u003e\n  \u003cli\u003eShuts off at 55 PSI for firm, household-style pressure\u003c\/li\u003e\n  \u003cli\u003e12 Volt DC operation wires straight into your boat or RV house system\u003c\/li\u003e\n  \u003cli\u003eAutomatic demand design runs when you open a tap and stops when you close it\u003c\/li\u003e\n  \u003cli\u003eInternal by-pass smooths low-flow cycling for even, pulse-free water\u003c\/li\u003e\n  \u003cli\u003eBuilt-in thermal protection lets it run dry without damage\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch NPMS male ports accept standard threaded plumbing fittings\u003c\/li\u003e\n  \u003cli\u003eSelf-priming design pulls water up from the tank on its own\u003c\/li\u003e\n  \u003cli\u003eCompact 8.1 in x 4.9 in x 4.3 in body fits tight pump bays and under-sink lockers\u003c\/li\u003e\n  \u003cli\u003eBacked by Shurflo by Pentair, a proven name in marine and RV water systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Shurflo by Pentair reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat are the flow rate and pressure?\u003c\/summary\u003e\n    \u003cp\u003eIt moves 3 gallons per minute and shuts off at 55 PSI, which gives you firm, household-style pressure at the tap.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat voltage does this pump run on?\u003c\/summary\u003e\n    \u003cp\u003e12 Volt DC.
