Step-by-Step Guide to Hard Plumbing RV Sewer

Now that we understand the benefits, let’s delve into the step-by-step process of hard plumbing an RV sewer:

Step 1: Gather The Necessary Tools And Materials

Before beginning the installation, make sure you have the following tools and materials:

Tools Materials
  • Measuring tape
  • Hacksaw
  • PVC pipe cutter
  • Screwdriver
  • Adjustable wrench
  • Drill with hole saw attachments
  • Pipe joint compound
  • PVC pipes in various lengths and diameters
  • PVC fittings (elbows, couplings, adapters, etc.)
  • P-trap
  • PVC glue
  • Silicone caulk
  • Screws

Step 2: Plan The Layout

Before cutting any pipes or starting the installation, plan the layout of the sewer system. Take measurements and identify the best route for the pipes, ensuring they are easily accessible and away from any obstructions.

Step 3: Install The Main Drain Pipe

Start by installing the main drain pipe that connects the RV’s waste tanks to the sewer outlet. Use a PVC pipe cutter or hacksaw to cut the pipe to the required length. Attach elbows and couplings as needed to create the desired path for the pipe.

Step 4: Install The P-trap

The P-trap is an essential component that prevents sewer odors from entering the RV. Install the P-trap between the main drain pipe and the sewer outlet. Use PVC glue to secure the connections and ensure a watertight seal.

Step 5: Secure The Pipes And Fittings

Once the main drain pipe and P-trap are in place, use pipe straps or brackets to secure the pipes and fittings to the RV’s undercarriage. This will prevent any potential movement or damage while driving.

Step 6: Create Access Points

It’s essential to create access points in the sewer system for future maintenance or repairs. Install cleanout fittings or access panels along the sewer line for easy access. Secure them tightly and seal any gaps with silicone caulk to prevent leaks.

Step 7: Test The System

Once the installation is complete, fill the RV’s waste tanks with clean water and check for any leaks or issues. Fix any problems that arise before using the system with actual waste.
