Tips for Caring for Your Sewer Hose 627

The sewer hose, lovingly referred to as the “stinky slinky,” is one of the most critical accessories for your RV.

Considering its purpose, routinely caring for your sewer hose system makes for a more enjoyable, less stressful camping experience.

Here are a few ways to make sure everything stays in good shape:

Follow the Correct Dumping Procedures

There are dozens, maybe hundreds, of different tank dumping procedures around the internet. A quick Google search returns over 1,730,000 results.

Most have at least this step in common: empty your black water tank first, then empty your gray water tank to flush out your sewer hose.

This ensures the worst of it is washed away with what should just be soapy water from the shower or sink. In fact, if you need to empty out your black tank, but don’t have much in the gray tank, it might be worth doing an extra load of dishes or taking a quick shower to make sure there’s enough to clean out your sewer hose.

Keep Your Black Tank as Clean as Possible

Sure, your tanks are made to hold some gross stuff, but that doesn’t mean you shouldn’t make sure they’re as clean as possible.

  • Use the tank flush—if your RV has one—when you get a chance. If it’s not equipped, you can use a tank cleaning wand.
  • Regularly treat your tanks with the recommended chemicals.
  • Use RV-friendly toilet paper.
  • Throw some dishwashing detergent and ice cubes into the tank and drive around (this helps dislodge debris from the sides of your black tank).

Add a Clear Elbow to Your Sewer Hose Kit

A clear sewer hose elbow is the only real way to know what’s coming out of your hoses.

Once the water runs clear, your hose is just about as clean as it’s going to get.

Use a Sewer Hose Rinse Cap

Ok, so there’s one more way to get your sewer hose even cleaner.

A sewer hose rinse cap will have one end as a standard water hose connection and the other as a bayonet to connect to your sewer hose.

This will shoot water directly into the sewer hose to rinse it out.

It should go without saying, but DO NOT use your fresh/drinking water hose to feed the sewer hose rinse cap. It’s not a direct connection between the inside of your sewer hose and the end of the fresh water hose, but better safe than sorry.

Keep Your Sewer Hose Out of the Dirt

We’ve spent a lot of time taking care of the inside of your sewer hose, now let’s focus on the outside.

Instead of laying your hose right on the ground, use one of these flexible sewer hose supports.

Besides keeping your hose off the ground, most models give a bit of incline to your hose as well. Let gravity help as much as possible.

Safely Store Your Sewer Hose While Traveling

A lot of people swear by the five-gallon bucket, but we prefer keeping sewer hoses outside of the main storage areas.

Just about every RV has storage for your sewer hose in the rear bumper. However, we recommend traveling with at least 2 lengths of hose—there’s no way to know how far the sewer pipe will be from your dump valve.

There are a few ways to store this second hose. The easiest way is to mount another carrier to your RV. If you’re crafty, some PVC pipe and a couple fittings will do the job too.

Your sewer hose is one of the most important things in your RV. Keep these tips in mind when caring for your sewer hose system, and the messiest part of RVing will be a breeze!
