How to Connect a Sewer Hose to an RV

How to Connect a Sewer Hose to an RV
Recreational vehicle sewer hookups have a simple design. The hoses and adapters connect without the use of tools. Each adapter only fits into its proper place, making the process simple for campers and outdoors enthusiasts using RVs.


Difficulty: Easy

Things You’ll Need:
  • Disposable gloves
  • Sewer hose
  • Valve adapter
  • Hose connector
  • Sewer connector seal
  • Sewer connector attachment
Step 1
Put on a pair of disposable gloves to protect your hands from being exposed to sewage or chemicals.
Step 2
Check the dump station's rules regarding RV sewer hose fittings before hooking your RV waste system to the dump station. Some dump stations require the use of screw-in sewer connector attachments; others require the use of a sewer connector seal.
Step 3
Visually inspect the sewer hose for holes or tears. Patch up holes or tears with a waterproof tape, or replace the sewer hose with a new one.
Step 4
Connect the valve connector to one end of the sewer hose. Depending on the model you have, the connector either screws or snaps into the hose.
Step 5
Attach the valve connector to your RV holding tank outlet. Turn the valve connector clockwise, until it will no longer turn, to seal the connection.
Step 6
Walk the free end of the sewer hose without dragging it to the sewer. If the sewer hose is not long enough, attach another sewer hose to it. To attach two sewer hoses together you need a sewer hose connector. Depending on the sewer hose connector you have, it either screws or snaps into place. Attach one end of the connector into each sewer hose to connect the two together.
Step 7
Attach the sewer connector into the end of the sewer hose. The sewer hose connector either screws or snaps into place.
Step 8
Slip the sewer connector seal over the sewer connector if the dump station requires the use of one.
Step 9
Fit the sewer hose connector into the sewer outlet. Push or screw it firmly into place to make sure that it does not come out during dumping.
Step 10
Open the holding tank on your RV to empty your onboard sewage. The lever or button to open the holding tank is located near the RV holding tank outlet. Depending on your RV model, the holding tank is opened with a push button, a pull lever or a twist lever. Consult your RV owner's manual if you are unsure of how to operate your holding tanks.
Step 11
Flush your sewer hose clean by emptying the gray water tank after emptying the black water tank, before disconnecting your sewer hose.
Step 12
Disconnect your sewer hose when finished dumping.

Tips & Warnings

Make sure the sewer hose is completely empty before disconnecting it from the sewer. You can tell if the hose is empty by lifting it up. An empty hose is extremely light in weight. If the hose is heavy, it is not empty.
Never drag your RV sewer hoses on the ground. Dragging can tear or puncture the hose.
