- Provides proper flow and drainage performance
Important: Verify your RV's drain orientation before ordering. If your RV has left-side plumbing, you'll need a left drain tank instead.

- Right drain works perfectly with wide footprint design
- Provides 45-gallon capacity in a space-efficient design
- Perfect for RVs with generous side-to-side clearance
- Ideal for wide basement storage configurations
Note: Professional installation recommended. You'll need to drill and install appropriate fittings, gaskets, and hardware based on your RV's plumbing system.

How do I know if I need right drain or left drain?
Check your existing tank's drain outlet location. If the drain is on the right side when facing the tank from the front, you need a right drain tank like the VR345175HBLANK. If it's on the left side, you need a left drain tank. Verify before ordering to ensure proper fit.
What does blank configuration mean?
