What Is Involved in Boat Plumbing?

While you may not think of a boat as having plumbing, most do. Unlike the plumbing in your home, the plumbing on a boat uses flexible tubes or hoses. Complex plumbing systems allow for showers, sinks and toilets for larger vessels. Even smaller fishing boats may have some plumbing if they have onboard tanks. Here is a brief overview of what to expect in your boat’s plumbing.


Boat plumbing fittings Newport Beach are designed to work with the flexible tubes and hoses that move the water around. O-ring seals, threaded fittings and connectors ensure the piping stays connected without leaking. Water leaking into the boat isn’t something you want to have happened. Keep in mind that the fittings are often more expensive than standard PVC fittings but the piping itself is often cheaper.


For those boats with sinks, showers and tubs, the boat has drains. Most often, the drain is located towards the centerline of the boat to prevent them from falling below the waterline as the boat moves along the waves. Sometimes the sinks and shower drain into the toilet to prevent flooding.


There are multiple pump types on board if there are multiple uses for water. A discharge pump is a good idea for those boats with a shower. This prevents clogging the bilge pump. Water pumps are necessary to get the water to various places. Manual pumps work by foot or hand while electric pumps are automatic.


Due to the weight of water, tanks are usually mounted beneath the boat. Depending on how much water is used or needed, multiple tanks may be mounted to allow more water storage. In addition, the boat may feature accumulators, hot water and a washdown depending on the size. Boating whether locally or around the world can be a fun pastime as long as the plumbing works properly.
