Using an RV sewer hose is essential if you are road-tripping in a self-contained motorhome (one that has a bathroom and/or a kitchen). At some point, you are going to have to get down to some nasty business and dump those black and grey water holding tanks. You’d be hard-pressed to find someone who thinks this part of RVing is fun, but the process doesn’t have to be messy or time-consuming. Follow these steps and you’ll be back on the road in no time. It also couldn’t hurt to read these black water tips before starting.
- Use disposable gloves. What you are about to do deals with gross grey water from your shower and sinks, and raw sewage from your RV toilet. It ain’t fun and can be a health hazard, so do yourself a favor and use gloves whenever you handle the hose or mess with any of the connections and caps.
- Make sure the RV sewer hose valves are closed. Yep, there’s a cap on the RV side, but make sure you have all the waste RV sewer hose valves shut before attempting to take it off. This makes sense, right? If you take that cap off with the valves open, you are in for a surprise.
- Connect RV sewer hose. Most RV sewer hoses have bayonet-style fittings and generally make a tight seal. Connect one side to the RV waste fitting, and extend the hose to the dump station’s inlet. Make sure to use an elbow (not yours, a fitting) that fits snug and deep into the dump station opening. You may need to use a soft sewer gasket depending on the dump station and location.
- Slowly open the black tank RV sewer hose valve first. This is an important step. Depending on how full your tanks are, you can expect there to be a good pressure surge as sewage enters the hose and makes its way to the dump station. Keep an eye on the elbow going into the dump tank for leaks, raw sewage shooting into the air, etc. Allow the tank to completely drain, giving it adequate time to trickle out at the end of the process. Close the valve.
- Drain the grey tank. After you’ve drained out the black tank and closed the valve, you can slowly open the grey water tank valve. Doing this second cleans out all that raw sewage from the hose. Just like the black tank process, keep an eye on things for leaks. Allow for things to fully drain.
- Close the RV sewer hose waste valves. At this point, you can go ahead and close both the black and grey water tank RV sewer hose valves. Be sure to look for any leaks from the valve itself, too.
- Disconnect RV sewer hose from RV. Twist to disconnect and pop the cap back on the waste valve.
- Spray down, clean up. At most places, there is a non-potable water hose – use that to spray down inside your sewer hose while it is still connected to the dump station. After that, remove the elbow from the dump station and spray it down, too. Spray down the concrete that surrounds the dump station.
- Stow away. Most RVs have a pipe or area designated for the RV sewer hose. Stow everything away where it belongs, keeping it out of contact from other stuff that may be in the same area.
- Disinfect. Remove gloves and throw away. Most dump stations have a trash can for used gloves. Use hand sanitizer as a precaution. As an extra step, you can use a spray disinfectant on the sewer valves and hose connections.
Now that wasn’t so bad, right? If you’re looking to get other dirty work out of the way, read these helpful tips for how to clean your RV awning.
