What is the Longest Sewer Hose for an RV?

What is the Longest Sewer Hose for an RV?

People use sewer hoses known as stinky slinky to dump RV waste tanks working on the natural gravity principle. Emptying black and gray tanks on your RV is the most challenging task due to the mess involved and the foul smell.

What is the Longest Sewer Hose for an RV? RV sewer hoses are available in a standard length of 10-feet to a maximum length of 25-feet. However, its size depends on the distance of the dumping station from your RV. You can increase the hose length up to the required distance by connecting multiple pipes by their male and female couplings. It is good to keep at least 2 lengths of sewer hose, 10 feet each, sufficient for most campgrounds during camping.

What should be the length of an RV sewer hose?

The length of an RV sewer hose required depends on the distance of the black tank from the dump station or sewer connection port at a full hookup campsite.

Typical lengths depend on the location of sewer hookup, whether at your home or a campground. For example, if there is a distance of 50 feet between the driveway or porch and sewer cleanout port, you need the same length of pipe.

The same is the case for a campground. If you don’t have sufficient sewer hose length available, you have to drive your RV up to the dumping station at home and complete the procedure.

Some campgrounds have separate hookups available at each parking spot for an RV. In such cases, a single length of 10-feet will be sufficient to clean the black tank.

Most RVers connect the tanks with connection ports and keep the valves open to drain the tanks automatically during their stay at the campground.

What is the longest sewer hose available for emptying an RV black tank?

The maximum length I have found in the market is around 25-feet. Usually, it is available in sections of 10-feet with bayonet clips. All you need to do is connect multiple extensions to achieve the desired length.

Some people find it tedious to carry multiple sections and link them at the time of disposal. Therefore, they move their vehicle at the dumping hookup to do the needful by using a single length of 10-feet. It is also not feasible to carry such a long pipe due to storage space constraints.

How to make an RV sewer hose longer?

These are available in sections of 10-25 feet, suitable for evacuating black tanks at a short distance from sewer hookup.

Most manufacturers offer extendible products with swivel lugs and bayonet fittings. Alternate sections have a male connector on one side and a female connector on the other side.

Insert the lug side of one hose in the bayonet side of the second pipe and rotate it to lock the connection.

Good quality pipes have 3-4 threads with a locking ring to ensure a leak-proof and odor-tight connection. Low-quality designs have 1-2 threads creating loose fittings that can leak while emptying the RV tanks.

Can we connect the RV sewer hose with PVC pipe?

PVC pipes have common usage in sewerage lines at your homes because of their durability and easy-to-use properties for making connections.

Experts recommend using PVC pipe from the dumping port to your camper for applications requiring more than 30-40 feet of sewer hose. 

First, purchase a PVC pipe of 3-4-inch diameter or according to your required size.

Next, connect it with the existing sewer line using a tee connection.

Next, make a connection port near your vehicle by using a compatible connector or bayonet fittings at the end of the PVC pipe.

Are RV sewer hoses available in standard size?

Yes, sewer hoses come in standard sizes with fixed lengths and diameters according to vehicle requirements. They have 3-4 inches diameter, and available lengths are 10-feet, 20-feet, and 25-feet.

All other fittings, including tee connections, elbows, bayonet, and lug connectors, are of compatible sizes.

People also connect PVC pipes for draining black tanks if hard-plumbing is a mandatory requirement by the campsite for an extended stay. They require a 3 to 4-inch conversion adapter for connection with the hose.

How many lengths of RV sewer hoses do you need to carry?

RVs have limited storage space available to store and carry these products with them. Therefore, you cannot accommodate having multiple pipe sections with you.

I will recommend taking at least 20-feet of length with you; that is a typical size to cover most of the campgrounds.

It helps you plan for the storage of the optimal length of the hosepipe. Besides that, keep an adapter or connector if you need an extension or find a different dimensions hookup at the campground.

What should be the compressed length of an RV sewer hose?

Sewer hose has flexible vinyl construction that is compressible to reduced lengths for storage. For example, the compressed size of a 10-feet pipe is about 2-feet.

Similarly, for 20-feet lengths, you will need 4-5 feet of storage space. It is a good feature enabling you to carry this essential tool during camping without needing much space. You can easily store them under the bumper or special tubes available outside the vehicle.

Effect of sewer hose length on its storage

Its length affects the space required for carrying it along the journey. Most RVs have 4-inch tubes or an area under the bumper to cater to the pipes inside.

However, you will need to buy storage tubes of compatible lengths for longer hoses. 

Decent-quality hoses have thicker walls, but they have increased compressed dimensions. Therefore, they need more storage space. Low-quality hoses require less space, but they can be easily damaged or punctured due to lesser thickness.

Effect of length on RV sewer hose price

Its price depends on its length and thickness. According to a market survey, its price can vary from $0.5-$3.0 per foot according to its quality and size.

It means with increased thickness and length, and you have to pay more. Moreover, additional storage tubes and connectors are other expenses for longer pipes.

Is there a 100 feet long RV sewer hose?

No, there is no sewer hose long enough to cover a distance of 100 feet. The easiest yet the expensive solution is to connect 10 segments of 10 feet hose extensions with coupling to get the required length.

Moreover, you will also require to create a slope for draining the waste.
