What to Look for When Buying a Marine Sanitation Hose


Before buying a marine sanitation hose, look into the following shopping guides first:

  • Burst Strength

Look for a hose that can actively resist pressure. As you know, the hose for discharge lines must be robust enough. Burst strength is generally gauged in PSI (Pounds Per Square Inch). This relies on the diameter and design of the product.

Please be guided that small diameter hoses come with superior burst strengths, so you should not look for anything bigger than a 2-inch marine sanitation hose. On the other hand, hose with several plies or helical reinforcement comes with higher pressure limits. Take note that this is essential for exhaust applications or pressurized water.

  • Reinforcement

A lot of marine hoses come with support in the walls. This is to ensure rigidity and more strength. Moreover, this is to impede expansion under pressure and avoid collapsing. As for the reinforcement, this could be vinyl/PVC helix, yarn spiral or wire.

  • Is it FDA approved?

Be reminded that if you intend to use the hose in potable water systems, it must be safe to use. It must come with anti-corrosion and anti-contamination features. It must be free from any toxic materials, too.

  • Bend Radius

The hose should not be bent more than the minimum bend radius. Be sure to consider this to allow proper installation. Always follow the recommendations of the manufacturer when setting it up. In so doing, you can impede breakage and kinks. This is particularly valuable for bilge pump and sewage lines applications.

  • Vacuum Rating

The hose on the intake side must be able to resist suction. The vacuum rating of the intake hose must be 20 or higher.

  • Range of Temperature

This is quite crucial for engine cooling hoses. However, this is also indispensable for pressurized hot water systems from water heaters.

  • Ease of Installation

Opt for some extremely flexible versions. Pick the one that can bend on a radius of roughly 3.25” without tangling. The hose should be easy to set up on standard hose barb fittings without the need to exert greater effort.

Indeed, the hose must be able to bend without the need to lubricate or heat it.

Other Important Factors to Consider


What is a marine sanitation hose?

Marine sanitation hoses are generally white in color. They come with a smooth bore that helps ward off the trapping of sewage that could lead to foul odors. This type of hose has an expected lifetime of roughly ten years.

The best sanitation hoses come with thick walls and are sleek inside. Hoses for sanitation purposes are clearly marked with indications like “sanitation hose” and printed on a stripe that runs the hose’s length.

Such hoses are flexible, durable and are low permeable. They could get clogged in the long run with uric acid and sewage from the head. Take in mind that using the wrong hoses can bring about severe issues such as bad smells.

As compared to other types of marine hoses, a sanitation hose is strong and sturdy enough for sewage applications.

How does it work?

Marine sanitation hoses are particularly for containing smelly gases. They act as water suction and discharge hoses. You can use them for wastewater and water.

In other words, this type of hose works to permeate the odor from the sewage. Take note that not all types of hose are capable of discharging waste. Sanitation hoses come with a liner that halts the transformation of sewage odor for a limited period.

What are the different types of marine sanitation hoses?

Truth is all types of marine sanitation hoses would smell sooner or later. This is particularly true if waste is allowed to stand for an extended period. So, options that come with sleek interior walls are ideal. The reason is that such corrugated types are adept at trapping sewage and can limit flow.

Hose permeation is one of the most typical causes of irking smells from sanitation systems. Thus, picking the suitable hose for new installation or replacement is crucial for making the system free of any terrible smell for a long time.

PVC, butyl and EPDM rubber are the most common types of materials used for sanitation hoses. Butyl rubber comes with more durable resistance against oils than EPDM. On the other hand, rubber hoses come with lower permeability features than PVC.

Both butyl and EPDM hoses feature more excellent resistance to alcohol utilized in winterization than PVC ones.

In addition to this, rigid or reinforced PVC is incapable of passing odors; however, it is tougher to transmit and does not link directly to pumps and thru-hulls. Even so, it is possible to plumb part of the system with solid or reinforced PVC and shifti hoses where needed.

You may go for sanitation hoses that come with odor-resistant features. Some can defy saltwater and corrosion.

As far as applicable, hoses should be run. This is to ensure that there is no permanent water in loops or sags to inhibit permeation and premature aging. This type of hose could get clogged sooner or later with scale by uric acid or sewage from the marine toilet.

Sure thing, using inappropriate hoses could bring about various problems such as terrible smells. Hence, this could result in making your boat unusable.

Why do you need marine sanitation hoses? (Benefits)

For sure, when it comes to marine sanitation, we all prefer options that come with outstanding expertise and quality. Buying the most suitable sanitation hose is quite critical because this can offer us lots of benefits to enjoy in the long run.

Some of the perks we can take pleasure in when getting the right sanitation hose include:

  • Premium quality sanitation hoses are flexible and act as an outstanding odor barrier
  • Since they come with an ultra-sleek interior surface, they work exceptionally in preventing leaks and clogs.
  • Some options come with rigid build and steel wire reinforcing helix so they could withstand rugged use for many more years to come.
  • Top-quality sanitation hoses can resist corrosion, saltwater and other harsh conditions.
  • High-end brands feature an odor shield that significantly helps restrict the spread of irking odor.
  • There are available options that can defy most chemicals and weathering.

Frequently Asked Questions


What are the most trusted marine sanitation hose brands?

Are you baffled by the search of the most appropriate marine sanitation hose? Well, this is a natural feeling, especially when it is your first time to purchase one. However, the most sensible approach is to conduct a research first regarding the most trusted brands.

Of course, this applies regardless of what products you decide to buy. The brand of your choice has a significant impact on the quality and performance of the product you choose. As you might already know, reputable brands never fail to produce premium quality products.

So, if you have plans of investing in a durable, reliable and exceptionally performing sanitation hose, the following brands are your top options:

  • Sierra International
  • Trident
  • Raritan

Shield sanitation hoses, especially the series 148 multi purpose vinyl hoses, and Sealand sanitation hoses are also products from reputable brand names. However, please take note that products produced by these manufacturers are commonly priced higher than their competitors, because quality, durability and incredible performance are guaranteed.

How to bend marine sanitation hose?

Not all sanitation hoses are flexible. And, sometimes, even if they are flexible, they are a little tough to bend.

Nearly all marine sanitation hoses will require some heat to be softened. To do so, you need to boil water and dip the edge of the sanitation hose in hot water until it becomes bendable.

Afterwards, it would push onto the barbs of the fittings. When the sanitation hose cools, it would no longer need any clamps. This is because when the sanitation hose cools, it can easily suit the fitting well.

Even so, you will need to slit the sanitation hose where it covers the fittings in the event you need to take the joint apart.

How to care and maintain?

Nearly all holding tank odors originate from the hose. You can take a careful inspection by running a neat fabric over the hose and smell it. If it smells nasty, this means that the hose is permeating and needs replacement.

If you are feeling doubtful that hose permeation might be the source of odor problems, dampen a fabric in hot water. Then, wrap the fabric around the suspicious hose and allow it to cool. Remove and smell the cloth.

The hoses are permeated if the irking smell transfers to the fabric. So, this means that it must be replaced. It is also crucial to inspect all the hose connections. This is specifically important for those that have the potential to catch waste.

Flush the system after use to lessen the possibility of sanitation hoses emitting an offensive odor. Take note that the hoses must be set up without any low spots where sewage can accumulate. You might already know that heating the hose to fit over barbed adapters could critically impair the hose. So, purchase fittings that are ideal to use for 1 1/2″ sanitation hose.

Indeed, if you have not cleaned your system in the past; and you’re feeling suspicious that you have a severe scaling concern in the pump and hoses, you can use 10% muriatic acid solution. This solution would help break down the buildup and won’t impair the plastic, rubber or porcelain components in your system.

Lastly, relying on your system’s hoses length, at least two up to four cups of this muriatic acid solution should be sufficient. Moreover, if the buildup is severe, then more than a single treatment might be needed.

What to keep in mind when dealing with marine sanitation hoses?

Here are the dos and don’ts:

  • It is a must to have a careful plan of your hose routing.

This is very critical because one of the primary causes of hose permeation is sewage that is left to amass in portions of the discharge plumbing line. As much as possible, avoid any avoidable sags or rises in the plumbing line. Furthermore, allow gravity to drain the hose.

It is essential to flush the marine toilet many times before you leave. Be reminded that replacing the outflow with only water would lessen the possibility of permeation more significantly.

  • Do not utilize lubricants or heat to aid in your installation.

There are sanitation hoses that come with a sleek interior. This helps make the barbed hose connections quite effortless to work with. Such models are capable of bending on a 3 ½ radius that makes them the most flexible sanitation hose available today.

  • Only utilize premium quality stainless steel hose clamps on all of your hose adapters.

Take into consideration that utilizing fasteners that could corrode or damage could result in waste leakage or disastrous flooding.

  • Avoid taking any shortcuts.

It is essential to ensure that all connections underneath the waterline are double clamped.

Some Valuable Points to Consider

  • Hose Connections

Smooth versus Barbs Adapters

Smooth connections are a lot easier to utilize; they can ensure a more excellent seal. And more importantly, they don’t cause severe damage to the hose. This is specifically true with rigid PVC hoses. They fit quite well on barbed fittings but difficult to remove.

Some forms of barbed or contoured fitting are still commonly recommended for high-pressure applications. However, some hose manufacturers point out rounded profiles these days. It is essential to check with the hose maker if the fitting appears to lose. Take into account that not all fittings are the ideal match.

  • Leaks

While it is true that permeation is the leading cause of offensive hose odors, it is not the sole cause. Inadequately cleaned waste, slow leaks around the hose clamps and fittings are also common causes.

Hence, it is a must to carefully examine the edges before speculating that you have a malfunctioning hose. Take note that a scored barb or crooked clamp typically allows leaks that won’t be solved by fastening a clamp.

While it is tempting to fix a leak through the use of silicone caulk or polyurethane sealer, this is merely a temporary solution. Moreover, it is not a good practice when setting up a new hose.

  • Sharp Turns

Several sanitation hoses are quite rigid and do not prefer sharp turns. In line with this, even if you could bend them, this approach weakens them. This is why most manufacturers assert that it is better to utilize a PVC elbow fitting if necessary than to twist a hose by forcing a turn.

The fitting would be larger than the tiniest passage in the marine head and should not cause any concern.

  • Hose Lubrication for Installation

Not to mention, a suitable lubricant could be a great aid in getting marine sanitation set up correctly. Go over the specifications of the sanitation hose to be sure that the lubrication is compatible.

For instance, since EPDM is not compatible with petroleum, your most excellent options would be glycol, K-Y or glycerine.

On the other hand, soap would work; however, this could leave non-drying debris that could intervene with a more protected fit. This is specifically true when utilizing non-barbed fittings.

  • Heat

Some suggest that using heat can be useful for rigid PVC to make it easier to bend or twist. Others do not recommend such an approach. Anyhow, moderation is the key. The fitting and the hose should be no more than warm to touch.

In general, the usual concern is that boat owners take heating excessively. So, as a result, the hose is damaged, and failures are blamed on the manufacturer.

There are sanitation hoses where hot water is necessary to allow the insertion of the fittings with fair effort.

  • Fitting the sanitation hoses a few inches long.

The removal of a sanitation hose may require the destruction of the hose. By allotting a few additional inches to play with would streamline future repairs.

Where to buy?

Marine sanitation hoses are available in many boating supplies and hardware local stores. However, buying in local stores can only offer you limited options to choose from. At times, high-end options are out of stock, too. In the same way, some claimed that buying sanitation hoses in local stores is more expensive.

Hence, one of the best sites to look for premium quality sanitation hoses is Amazon. This online shopping site can offer you countless options. The world’s most highly acclaimed brands are also found here.

Besides, Amazon offers the best shopping deals. Shoppers can enjoy exclusive discounts, freebies and special promos that can help you save more. Money-back guarantee programs also support most of their products. So, your investments are safe.
