A marine plumbing system can make a boat much more comfortable and provide its crew and passengers with essential benefits. You can take a shower, cook dishes, store potable water, and use raw water for washing a deck or other purposes. However, the system has to be installed properly, and its configuration has to meet certain requirements and safety standards. For instance, it's not recommended to install ordinary ball valves as seacocks. Instead, go for marine-grade products designed for this purpose, which have specially arranged inner threads and other solutions to provide the necessary tightness and longevity.
On our virtual shelves, you can choose from numerous boat valves & pressure regulators that can be used in marine plumbing systems. In particular, we carry 3-, 4-, or even 5-way valves that are normally used to switch among several tanks of water or connect to the municipal water supply available in some docks. In the last case, you may need a pressure regulator to protect your boat's fittings and hoses from high pressure surges. Available in numerous diameters, our valves and fittings are made of bronze, stainless steel, nylon, or plastic and feature different connection types meant for pipes or hoses.
