- Travel trailer black water tank replacement with left-side plumbing
- Class C motorhome waste tank upgrades
- Fifth wheel holding tank repairs

- Custom RV builds requiring 30-gallon capacity with left drain
- Replacement for damaged or leaking left drain holding tanks
- Applications requiring left-side plumbing connections
- Extended trip RVs needing reliable waste storage
Left Drain Orientation - What It Means
The VB23528HL features left drain orientation (HL), which means the drain outlet is positioned on the left side of the tank when viewing from the front. This is critical for proper installation:
- Ensures drain outlet aligns with your RV's existing plumbing
- Matches factory configurations for left-side drain systems
- Eliminates need for custom plumbing modifications
- Provides proper flow and drainage performance
Important: Verify your RV's drain orientation before ordering. If your RV has right-side plumbing, you'll need the right drain version (VB23528HR) instead.

How do I know if I need left drain or right drain?
Check your existing tank's drain outlet location. If the drain is on the left side when facing the tank from the front, you need a left drain (HL) tank like the VB23528HL. If it's on the right side, you need the right drain version (VB23528HR). Verify before ordering to ensure proper fit.
