Water Outlets & Washdown Spigots

What Are Marine Water Outlets & Washdown Spigots?

Water outlets and washdown spigots are essential components of any well-equipped boat's onboard plumbing system. Water inlets serve as the dedicated entry point for shore water to enter your boat's pressurized system, while water outlet fittings are used for discharging water or providing a connection point for on-board systems — most commonly washdown pumps used for cleaning decks or anchors after a day on the water.

Whether you're rinsing salt spray off the deck, flushing out a live well, or connecting to a marina's dockside water supply, having the right fitting in the right place makes the difference between a convenient, leak-free system and a frustrating maintenance headache.

Why Quality Matters in Marine Plumbing Fittings

The marine environment is uniquely demanding. Saltwater, UV exposure, vibration, and repeated wet-dry cycles can quickly degrade fittings made from inadequate materials. Marine-grade water outlets and inlet valves are built to resist corrosion and wear, helping maintain long-term reliability in both saltwater and freshwater applications. Look for fittings constructed from corrosion-resistant materials such as 316 stainless steel, chrome-plated bronze, or marine-grade brass — all of which are commonly found in this category.

It's also worth considering the pressure demands placed on your system. Dockside city water systems can deliver unregulated pressures that stress hoses and fittings over time. Choosing properly rated outlets and spigots ensures your onboard plumbing handles the load safely and consistently for the long haul.

Key Considerations When Shopping

• Material: Stainless steel and chrome-plated bronze offer the best corrosion resistance in saltwater environments.
• Fitting size and thread type: Most outlets use standard garden hose (GHT) or NPT pipe thread connections — confirm your existing plumbing before purchasing.
• Flush-mount vs. surface-mount: Flush-mount designs provide a cleaner look and reduce snagging hazards on deck.
• Plug or cap inclusion: Many quality fittings include a watertight plug or cap to protect the connection when not in use.
• Application: Determine whether you need a freshwater inlet (for shore hookup) or a washdown outlet (for deck cleaning systems), as the two serve different functions.
