​Why Sanitation Hoses Are Important for Your Boat

19th Jan 2023

If you own a boat, you know that there are a lot of different parts and pieces that go into keeping it running smoothly. One important piece of equipment is the sanitation hose. This hose is responsible for carrying waste throughout your boat’s sanitation system, whether it’s from your marine toilet to the holding tank or from the tank to a proper disposal system.

While it may seem like a small part of your boat, having a properly functioning sanitation hose is actually very important. That’s because if there is any leakage or permeation, your boat will wind up smelling like waste or raw sewage. Unfortunately, many first-time boat owners think they can simply connect any type of rubber hose to their marine toilet (either a vacuum flush or macerator) or holding tank. This approach will quickly result in some unpleasant (and foul smelling) outcomes.

What Are Sanitation Hoses?

Sanitation hoses are specifically designed for use in marine systems. They are made of highly durable material (usually PVC, which is ideal for marine plumbing applications) that can withstand the high temperatures and pressures associated with boat toilets, blackwater tanks, and other sanitation systems. This type of hose is often reinforced internally as well as externally so that it can handle the weight of waste and other liquids that are transported through it. This reinforcing also helps make sure that the hose does not collapse under pressure or kink up over time.

Sanitation hoses come in a variety of sizes and lengths so you’re sure to find one that fits your needs. While they may be more expensive than other types of hoses, they’re definitely worth it in the long run. That's because conventional rubber hoses are extremely vulnerable to a process known as hose permeation, which can cause bad odors and cause damage to your entire sanitation system over time.

What is Hose Permeation?

Hose permeation is a process where raw sewage or other liquids pass through or absorb into the hose material, causing unpleasant smells to be released. This happens when bacteria breaks down the raw sewage inside the hose and creates anaerobic gases like methane, which then pass through or absorb into the hose material. Over time, this can cause the hose to weaken, resulting in holes or cracks that release even more odors.

Using the incorrect hose material in a marine sanitation system will greatly accelerate the permeation process. That’s why it's important to choose a reinforced hose that is specifically designed for sanitation use. This type of hose will have the least permeability possible and also be strong enough to handle the weight of waste and other liquids without collapsing or kinking up.

Selecting and Installing a Marine Sanitation Hose

The best sanitation hoses are thick-walled and smooth inside. Reinforced PVC is an excellent choice. Hoses for sanitation use are clearly marked, most often with the words "sanitation hose" printed in a stripe running the length of the hose. Although it's tempting to use other types of hose that may be more flexible, don't. Smells and other problems are sure to follow because the material used to make these hoses are much more permeable. Aside from being strong, holding tank sanitation hoses must have the least permeability possible prevent odors from escaping.

Hoses should be run, as far as practicable, so that there is no standing water in sags or loops to prevent premature aging and permeation. If standing water is allowed to accumulate, the hose can eventually get clogged over time with scale by waste and uric acid from the boat toilet.
