Understanding Blank Tank Configuration
This is a \"blank\" holding tank, meaning it arrives without pre-drilled holes for fittings. This gives you complete flexibility to position drain outlets, vent connections, and sensor ports exactly where your RV installation requires. You'll need to drill and install your own tank fittings and accessories based on your specific plumbing configuration.
Benefits of Blank Tank Design
- Custom fitting placement for perfect alignment with existing plumbing
- Flexibility to add multiple drain points or sensor locations
- Ability to orient tank in any direction to fit your space
- No unused pre-drilled holes that could become potential leak points
- Compatible with any brand of tank fittings and accessories
Rotational Molding: Superior Tank Construction
Unlike cheaper welded or blow-molded tanks, this Alpha holding tank uses rotational molding technology to create a seamless, one-piece construction. During manufacturing, polyethylene resin is heated and rotated in a mold, creating uniform wall thickness throughout the entire tank with no seams, welds, or weak points. This process produces the strongest, most leak-resistant tanks available for RV applications.
Why Rotational Molding Matters
- No seams or welds that can separate over time
- Consistent wall thickness prevents thin spots and stress fractures
- Superior impact resistance compared to blow-molded alternatives
- Better resistance to chemical degradation from waste and treatments
- Longer service life with fewer warranty claims
Installation Considerations
Before ordering, carefully measure your available installation space and verify this tank's 54x32x7 dimensions will fit. The low 7-inch height makes this tank ideal for installations with limited vertical clearance, such as under-floor mounting or in shallow basement compartments. Ensure you have adequate access for drilling fitting holes and installing the tank in position.
What You'll Need for Installation
- Tank fittings (drain outlets, vent connections, sensor ports)
- Hole saw or step drill bit for fitting installation
- Tank mounting straps or brackets
- Plumbing connections to match your existing system
- Tank level sensors (if desired)
- Sealant rated for waste water applications
