Factors to Consider When Purchasing Marine Plumbing Parts and Supplies

If you are considering getting yourself some new marine plumbing parts or supplies, there are several factors you should consider before making your purchase. These include standards, fittings, water reservoir tanks, and prices.

Water Reservoir Tanks

You’ll need to consider a few factors to purchase marine plumbing parts and supplies. The type of tank, the fittings, and the discharge options will depend on your needs and your boat’s size.

Typically, a water reservoir tank has one outlet. These types of tanks are usually made from plastic. They have a wall thickness of around 1/8 inch.

Plastic water storage tanks are usually available in a standard size. Their height and width increase with increasing altitude. However, they are susceptible to flexing at the piping connections. You can restrain the hoses with plastic wire ties or clamps.

Water tanks should be vented. This will prevent the tank from overpressurizing. Vents also keep the pressure equal inside the tank.

Invest in a coastal holding tank if your boat is near the coast. It is designed for use in places where people have no other way of disposing of their waste.

Proper Fittings

As a boat owner, you must know what fittings and supplies you should use to keep your plumbing system running correctly. These systems are very stressful and can get fouled when you’re out on the water. It’s also crucial to have a suitable hose that can withstand the pressure of your boat.

Plastic fittings are often better than metal fittings. When they’re installed correctly, plastic fittings can be handy.

Several materials make up plastic pipe connectors. Some of the more popular materials are poly-vinyl-chloride (PVC) and ABS. Both are more durable than bronze or steel.

However, when installed correctly, plastic fittings are just as valuable. Nylon is an excellent choice for those who work with chemical solvents and potable water. Unlike PVC, nylon is highly resistant to corrosion.

A soft copper tube is a good option for many marine plumbing jobs. But in the end, it all comes down to finding the correct fitting for the job.


To get the most out of your dollar, you’ll want to purchase plumbing parts and supplies made from quality materials that will stand the test of time. A poorly constructed plumbing system can do more harm than good in the long run. You can avoid a costly mistake by taking the time to research your options and choosing a plan that will do the job right the first time, every time.

One of the easiest ways to accomplish this is to shop around. Many manufacturers offer high-quality marine plumbing parts and supplies that are sure to last for years to come. For example, you can opt for an American Standard product that is made of quality material, is well stocked with plumbing parts and is designed for the style of boat you’re building. The standard is not confined to the bottom of the ship either; there are plenty of options that can be tucked away under the hood or even in the engine compartment itself.
