- 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.

- Stay longer at boondocking sites without dumping
- Reduce frequency of dump station visits
- Support full-time RV living comfortably
- Accommodate larger families or groups
- Enjoy extended trips with peace of mind
Note: Professional installation recommended. You'll need to drill and install appropriate fittings, gaskets, and hardware based on your RV's plumbing system.

The Alpha 940BLANK holding tank has a 50-gallon capacity for black water storage. This is a large capacity tank, providing substantial waste storage for extended RV trips and full-time living.
What does right drain orientation mean?

What are the dimensions of the 940BLANK?
The 940BLANK measures 64" long x 32" wide x 8" tall. The generous 32" width provides maximum capacity while maintaining a low 8" profile. Make sure to measure your RV's tank compartment carefully, allowing extra space for fittings, connections, and mounting hardware.

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 940BLANK. If it's on the left side, you need a left drain tank. Verify before ordering to ensure proper fit.
Will this fit my Class A motorhome?
