The 39551 is less adaptable since it has permanently connected elbow and bayonet connections, unlike other Camco hoses with removable fittings.

Optimal RV Sewer Hose

What to Consider Before Purchasing RV Black Water Hoses

#1. Materials

Many RV hoses are composed of materials that are unsuitable for transporting portable water, including the water you use for cooking and drinking.

When purchasing RV hoses that will be used for drinking, cleaning, or cooking, look for the phrase “drinking water safe” on the packaging.

This indicates that the hoses are free of lead, bromine, and other chemicals that might contaminate drinking water.

Instead, they include polyurethane or polyurethane materials made from polyethers that have UV stabilization.

Additionally, you should be aware that the drinking water safe hose may be quickly recognised by color.

They are usually available in either white or blue.

Also keep in mind that PVC hoses that claim to be lead-free may include other toxic chemical substances including phthalates, bromine, and antimony.

You may use any of these hoses for RV sewage hoses regardless of the material it is made of, however it is wise to purchase hoses in colors other than white and blue so you can distinguish them and store them separately.

#2. Length/Thickness

The length of an RV hose is sometimes determined by how far the RV is from a spigot or a dump station.

Hoses for RVs are always made in conventional lengths.

Most of them are 10 feet, 25 feet, and 50 feet long, with a thickness of 15 to 26 mils, or approximately 1/2 inch.

While the maximum length for an RV sewage line is typically 25 feet, the maximum length for a drinking water hose is 50 feet.

You may either purchase many shorter hoses or a single 50-foot long hose if you want a hose that is longer than 50 feet.

Due to fewer connections between the pipes, the single long hose helps to decrease the likelihood of leaks and also avoids water pollution.

But compared to utilizing many small hoses joined together, a single long line might also be more challenging for you to clean and store in the RV.

#3. Price

RV water hoses that are heated cost more than standard RV hoses.

When camping in locations where the freezing point is more likely to occur, they protect a pipe from breaking.

When in these very cold places, normal hoses freeze and get damaged.

Due to their excellent insulating qualities, they are also known as insulated water hoses.

They are often blue in color.

The heat strip, an electrical device, is often included with this kind of hose.

The heat strip is hooked into a valve next to the hose, warming it and preventing the water from freezing.

When the heat strip is not plugged in, the hose may also be used as a typical RV hose.

Last but not least, the price of an RV hose depends on its size and length.

Hoses that are longer in length are often more costly than those that are shorter.

#4. Portability/Storage

RV hoses may be readily stowed in the area provided in the RV bumper since they are compressible.

It is more difficult to store 50-foot hoses than shorter ones since the majority of RVs do not have adequate storage space for them.

As an alternative, they may be folded and stored within the RV in a container.

The 10-foot long hoses may also be compacted for simple storage to a length of around 3–4 feet.

However, employing many short, 10 foot hoses coupled together may easily result in water leaks and water contamination.

The advantage is that connectable small hoses are always simple to disinfect since you can always detach them to wash them inside and dry them off more quickly than lengthy hoses.

#5. Cleaning

When attaching your RV hose to the faucet after cleaning it, it’s crucial to inspect the end for any lingering dirt particles.

Additionally, sterilizing your drinking water hose at least twice a year is advised.

This may be accomplished by briefly immersing the item in water that includes a bleaching chemical agent and then washing it.

After your camping vacation, be sure to drain all the water from your hose before disconnecting it to avoid germs like algae, spirogyra, and others that are drawn to water readily spreading within the hose.

The end of the hose should also be protected after disassembling it by hose caps or a plastic cover.

The cleaning method described above is more appropriate and practical when you have shorter RV hoses since longer RV hoses are harder to clean than shorter ones.

#6. Accessories/Attachments

A water filter is essential for your drinking water hose in terms of extra accessories and add-ons since it helps to eliminate contaminants that give the water an undesirable flavor and odor.

In order to utilize the water filter successfully, you need also replace and clean it often as directed by the producer or maker.

To regulate how much water flows into your RV, you also need water pressure regulators.

Low water pressure makes it hard to utilize the proper amount of water for any operation you need to accomplish, like cooking or taking a bath, while high water pressure might damage your RV’s components.

In order to connect your hose to your RV without damaging it, a 90 degree elbow is also required.

Due to its endurance, brass is often used in their construction.

Last but not least, a fast connect, which is often constructed of brass, is the device used to quickly join many hoses together.

They are strong and built to resist strong water pressure.


How do I determine the size of the RV sewage hose I need?

Purchase an RV sewer hose that is about the same length as the tube connecting your RV’s sewage pump output to the back of your motorhome.

Make sure you purchase more feet or have an extension since some RV parks have far-off dumping facilities in the rear.

RV sewer hoses are they universal?

RV sewage pipes of today are quite similar.

They are put together with equal parts.

They have a three-inch diameter, roughly.

You must install a sewage hose fitting at the end of certain RV sewer hoses.

The task of mounting fitting is made easier by RV sewage hoses that include a size ring.

The simplest fittings are the bayonets that come pre-installed.

The dimensions of RV vehicles and camp sewage lines are taken into consideration while manufacturing RC sewer hoses.

Do I need support for my RV sewer hose?

In virtually all circumstances, you will want an RV sewer hose support, which is advantageous.

It elevates the RV home off the ground, keeping it clean and shielding it from people’s feet.

Additionally, it maintains the RV sewage line in a slide-like configuration to ensure efficient drainage.

How do I clean the sewage hose on my RV?

Cleaning the sewage in your RV is a necessary evil.

You must adhere to these instructions for a quality cleaning.

Prior to flushing the grey water line, do the black water pipe.

Among them, Blackwater is the dirtiest.

The next step is to clean your sewage tank using a bleach and water solution.

Once there is no longer any debris, let it rest for a bit and rinse it many times.

Don’t forget to clean the fittings as well.

The fitting should then be cleaned by being separated and submerged in bleach water.

Last but not least, you may also use a disinfectant or enzyme solutions created especially for cleaning RV sewer hoses.

How should I keep my RV hoses?

Your RV sewage lines may be stored using a variety of techniques.

The most typical technique is utilizing a bucket.

A built-in RV sewage hose is a feature of certain RVs.

An alternative is a plastic box.

In addition to all of these options, you may simply purchase a pre-made RV storage tube or make your own from PVC tubes.

Remember to keep RV sewage hoses carefully since they may still retain pathogens after being rinsed because they contain many bacteria, dirty water, and feces.
