Connect a garden hose at the slip and run the whole system on shore pressure, no pump cycling and no draining the tank. It's flush-mount, potable-water rated, and one of those upgrades you stop thinking about once it's in.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis Xylem fresh water inlet is the fitting that lets you run your boat's plumbing straight off dockside water while you're tied up at the slip. Instead of drawing down your fresh water tank and cycling the pump every time someone opens a faucet, you connect a garden hose to the 3\/4 inch inlet and the whole boat runs on shore pressure. Simple idea. It saves your pump and your tank for the days you're actually off the dock, and for a lot of boaters that alone is reason enough to add one.\u003c\/p\u003e\n\u003cp\u003eThe part that earns its keep here is the built-in pressure regulator. Marina water pressure is all over the map. Some docks push 60, 70, even 80 PSI, which is a lot more than most marine plumbing was ever built to handle. This inlet caps the incoming pressure at 45 PSI before it ever reaches your lines. That protects your fittings, your hoses, and your fixtures from the slow leaks and blown connections that tend to show up after a season of running overpressure. You set it up once and forget about it. No gauge to watch, no adjustment to make.\u003c\/p\u003e\n\u003cp\u003eThere's also a built-in check valve. That's the piece that keeps dock water from backfeeding into your fresh water tank when the tank fill and the shore inlet share plumbing. It's a one-way gate. Water comes in, and it doesn't sneak back out the way it came. Worth knowing the check valve is a wear item. If you run dockside water hard for a few seasons, especially where the dock pressure likes to spike, the valve can stop reseating cleanly and you'll want to clean or replace it. Cheap insurance against a backflow surprise in your tank.\u003c\/p\u003e\n\u003cp\u003eInstallation is a flush mount. You cut an opening to the 4-3\/8 inch by 4-1\/8 inch footprint and the bezel sits clean against the hull side or a locker door. Cut the hole to size. The folks who trim it a hair small end up fighting the bezel to seat. The inlet side is a 3\/4 inch garden hose thread, so any standard potable water hose threads right on. The outlet is a 1\/2 inch 14 pipe thread that ties into your boat's fresh water manifold. Give those outlet threads a couple wraps of Teflon tape, a little more than you'd think if you're threading into aluminum, and you won't be chasing a weep at that joint down the road.\u003c\/p\u003e\n\u003cp\u003eOne thing to plan for is the mounting surface. The plate wants something flat. On a curved cabin side or a rounded transom, add a backing plate or a filler block so the bezel seals all the way around. On a 30 to 40 foot cruiser with a normal fresh water setup, this inlet does exactly what you need it to. If you're running a high-flow pump over 4 gpm, just know the 1\/2 inch outlet is the limiting factor, so size your expectations to the plumbing you've got. For most weekend cruisers and liveaboards at a marina, that's a non-issue.\u003c\/p\u003e\n\u003cp\u003eThe whole assembly is white and rated for potable water, complying with CSA under IAPMO TS 28 and NSF-18, so it's safe on the drinking water side of your system. It's an exterior part by nature, it lives on the outside of the boat, so on a sun-baked flybridge the white can yellow over time and the internal diaphragm ages like any plastic left in the sun. That's normal. Rinse it now and then, keep half an eye on the check valve, and it'll give you years of easy dockside hookups. For anybody who splits time between the slip and open water, a shore water inlet like this one is the kind of upgrade you stop thinking about the day after it's in.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eBuilt-in pressure regulator caps incoming dock water at 45 PSI to protect onboard plumbing from marina overpressure\u003c\/li\u003e\n  \u003cli\u003eIntegrated check valve stops dock water from backfeeding into your fresh water tank\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch GHT inlet accepts any standard potable water garden hose\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch 14 NPT outlet threads directly into your boat's fresh water manifold\u003c\/li\u003e\n  \u003cli\u003eFlush-mount design with a 4-3\/8 inch by 4-1\/8 inch footprint for a clean exterior install\u003c\/li\u003e\n  \u003cli\u003eWhite potable-water-safe housing complying with CSA (IAPMO TS 28) and NSF-18\u003c\/li\u003e\n  \u003cli\u003eRuns the boat on shore pressure so your pump and tank rest while you're at the slip\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 Xylem 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 does this fresh water inlet actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt gives you a dockside connection point so your boat's plumbing runs off shore water while you're at the slip.
