Why Choose the Alpha VR22466HBLANK Holding Tank?
When you need a reliable 18 gallon RV holding tank that fits in tight spaces, the Alpha VR22466HBLANK delivers the perfect balance of capacity and compact design. The 46" x 22" x 6" dimensions make this tank ideal for pop-up campers, small travel trailers, and RVs with limited underbelly clearance where standard tanks simply won't fit.
Unlike cheaper aftermarket tanks, this rotational molded holding tank features seamless one-piece construction that eliminates the weak points and potential leak areas found in welded or multi-piece designs. Each tank undergoes rigorous leak testing before leaving the factory, ensuring you receive a dependable waste management solution that won't fail on the road.
The center drain configuration provides superior waste evacuation compared to end-drain designs, making dumping faster and winterization more thorough. Whether you're replacing a failed OEM tank or upgrading from an undersized unit, the Alpha VR22466HBLANK offers the quality and reliability your RV deserves.

Frequently Asked Questions
How do I install the Alpha VR22466HBLANK holding tank in my RV?
Installation requires removing the old tank, positioning the new tank in the mounting location, securing it with appropriate mounting straps or brackets to the RV frame, and connecting the drain fitting to your existing waste plumbing. We recommend professional installation to ensure proper sealing, secure mounting, and compliance with RV waste system standards. Always verify clearances and mounting points before beginning installation.
Is this holding tank compatible with my pop-up camper?
The Alpha VR22466HBLANK's 46" x 22" x 6" dimensions make it ideal for many pop-up campers and compact trailers, but compatibility depends on your specific model's underbelly space and mounting configuration. Measure your existing tank or available installation space carefully, paying special attention to the 22" width requirement and ensuring adequate clearance for the center drain fitting.
What's the difference between center drain and end drain holding tanks?
Center drain tanks like the VR22466HBLANK position the drain outlet in the middle of the tank bottom, allowing for more complete waste evacuation and easier winterization since waste flows from both directions toward the center. End drain tanks have the outlet at one end, which can leave residual waste in the opposite end but may be necessary for certain RV plumbing configurations.
Can I use this tank for both black water and gray water?
While this tank is designed primarily as a black water (toilet waste) holding tank, it can technically be used for gray water (sink/shower drainage) applications. However, we recommend using tanks specifically designated for their intended purpose to maintain proper RV waste system separation and comply with dumping station regulations.
How do I winterize the Alpha holding tank?
To winterize, first completely drain and flush the tank at a proper dump station. Then add RV antifreeze through your toilet or drain connections until it appears in the drain outlet. The center drain design of the VR22466HBLANK makes winterization more effective since antifreeze reaches all areas of the tank more easily than end-drain configurations.
What's the weight capacity for mounting this holding tank?
When full, the Alpha VR22466HBLANK holds approximately 150 lbs of waste (18 gallons at ~8.3 lbs per gallon) plus the 15 lb tank weight. Your mounting system must support at least 165-200 lbs with appropriate safety margin. Use heavy-duty mounting straps or brackets rated for RV holding tank applications and secure them to structural frame members, not just floor decking.
