Frequently Asked Questions

Will this tank fit my pop-up camper or micro RV?

The 261BLANK is designed specifically for the smallest RVs, pop-up campers, and micro travel trailers. Measure your existing tank compartment (20.75" x 16" x 9") and verify drain location before ordering to ensure proper fitment.

Is 12 gallons enough capacity?

For pop-up campers and micro RVs with 1-2 occupants on weekend trips, 12 gallons provides adequate capacity. For longer trips or more occupants, you may need to dump more frequently or consider a larger tank if space allows.

Why does this tank have a perfect 5-star rating?

Customers consistently praise the 261BLANK for its exceptional quality, perfect fitment in ultra-compact spaces, leak-free performance, and long-lasting durability. The OEM-grade construction and rigorous leak testing ensure reliable performance.

How long will this tank last?

With proper care and maintenance, Alpha holding tanks are built to last for many years, often outlasting the RV itself. The seamless rotational molded construction eliminates common failure points found in welded or multi-piece tanks.

Is this tank leak-tested?

Yes, every Alpha 261BLANK tank is individually leak-tested at the factory to ensure quality and reliability before shipping.

Can I install this tank myself?

While experienced RVers can install holding tanks, we recommend professional installation to ensure proper mounting, plumbing connections, and vent configuration for optimal performance and safety.
