If you own an RV and want to stay parked at home or on a long-term site, you might be wondering how to permanently hook up an RV to a septic system. While many RVers get by with temporary hoses and weekly dumps, a permanent hookup makes life easier—no more dragging hoses or moving your rig just to empty tanks. Done correctly, it’s convenient, sanitary, and fully legal. In this guide, we’ll explain the process, the equipment you’ll need, and the best products to make a permanent RV-to-septic connection that lasts.
Quick Picks: Best Equipment for Permanent RV Septic Hookups
- Camco RhinoEXTREME 20-Foot RV Sewer Hose Kit – Best Overall: durable, crush-resistant hose designed for permanent and seasonal setups.
- Polylok 24″ Septic Riser Kit with Lid – Best Budget: brings the septic inlet to grade, making RV connections simple and clean.
- Liberty Pumps Pro380 Sewage Ejector Package – Best Premium: a full basin + pump system for when your RV sits below the tank inlet.
Buyer’s Guide: Key Things to Know Before Connecting
- Local Codes: Some municipalities require permits or specific fittings for permanent RV connections.
- Tank Location: Make sure your septic tank has an accessible inlet or riser near where you’ll park the RV.
- Gravity vs. Pump: If the RV drain is higher than the tank inlet, gravity works. If not, you’ll need a sewage ejector pump.
- Pipe Material: PVC pipe is the best choice for permanent lines—rigid, durable, and less prone to leaks than flexible hose.
- Access for Pumping: Adding a riser makes it easier for pump trucks and also simplifies the RV tie-in.
Step-by-Step: How to Permanently Hook Up Your RV
- Locate the Septic Inlet: Find the cleanout or add a riser kit to your tank inlet.
- Lay Out the Route: Plan the shortest path between the RV outlet and the tank inlet.
- Choose Your Connection: Use rigid PVC pipe for a true permanent hookup, or heavy-duty hose for seasonal setups.
- Seal the Joints: Use proper fittings and rubber gaskets to ensure no leaks or odors.
- Secure and Test: Make sure the line is supported and has proper slope before running a test dump.
- Add a Pump if Needed: If the RV outlet sits lower than the tank inlet, install a sewage ejector pump system.
