Boat Plumbing

It is significantly more straightforward for the do-it-yourselfer than plumbing at home, fundamentally because it doesn’t include rigid lines running inside solid walls. With this houseboat, plumbing includes freshwater pumps, heaters, tanks, accumulators, faucets, and shower drains.

Since water is heavy, tanks must be mounted low in the boat. Where space is accessible, it is moderately simple to make a difference to add additional tanks. Rigid polyethylene tanks are accessible in many shapes and sizes, or you may utilize an adaptable bladder tank,  basically a water pack. Most tanks are box-like shape and designed to comfortably fit in a tight space. The size range is from 15 to 30 gallons, and remember that polyethylene should be kept sanitized.

You can use electric or manual pumps on your boat. An Electric pump pressures the whole water system while the manual pump is “hand or foot operated.” This means that a single plug manual pumps supply is connected directly to the outlet outside the pump. And the primary advantage of manual pumps is that they reduce water, which is a significant concern for spending long periods away from water supplies.  


An accumulator is a tank that is installed downstream of the pump. Large accumulators contain pressurized bladders, but the majority are simply empty tanks. The tank’s pressure allows for small amounts of water to be drawn without the need for the pump to run.

Hot Water

A marine water heater is nothing more than a small tank located downstream of the pump. To run a water heater, you must have a pressurized water system. The pump pulls water from the storage tank(s) and empties it into the water heater tank. It consists of an electrical heating element and a coiled tube known as a heat exchanger.

Water heaters feature four threaded ports. When plumbing a water heater, use only metal fittings and never plastic. If a pressure-release valve isn’t built-in, the heater will have a fifth port for it. A tee connector links the tank inlet to the pump’s outflow line.


Faucets are the final destination for water system lines. Mixer faucets require the cold side to the pump’s supply line and the hot side to the water-heater output. Boats can also be outfitted with hose barbs instead of spigots for increased efficiency.


A deck shower is a wonderful feature to nearly any boat and is simple to install by teeing into the cold and hot water supply lines. Shower connections are similar to faucet connections, except water is supplied through a pipe or hose to the showerhead.


Sink drains are generally connected to a through-hull fitting with reinforced rubber tubing. Sinks should be placed near the centerline to not go below the waterline when the boat is heeled. To minimize flooding, head-sinks can be connected to drain into the toilet bowl.

Shower pans should be separated from the bilge and equipped with a discharge pump, either automated or switch-operated. The through-hull discharge outlet must always be kept above water, and the exhaust exit must always be kept clear of the ship’s bilge.


A washdown pump is an excellent convenience for hosing the deck and knocking mud off the anchor chain. Since few boats carry sufficient freshwater, washdown pumps are not connected to the freshwater system.

Heavy-duty rubber suction hose with wire support to protect it from collapsing. Debris will harm or ruin a washdown pump; thus, a strainer in the intake line is required. Use a Y- or tee connector to connect a deck wash pump to an existing inlet line. If installing a deck wash pump, use a Y- or tee-connector to tie into the current inlet line.
