What Makes Alpha Tanks Superior?
Alpha has built a reputation for manufacturing premium RV water tanks that outlast and outperform the competition. Every Alpha tank undergoes rigorous quality control to ensure it meets the highest standards for potable water storage. The seamless rotational molding process creates a tank with uniform wall thickness and no weak points, while the FDA-approved polyethylene material ensures your water stays pure and safe.
Unlike cheaper alternatives that may use recycled plastics or inferior manufacturing processes, Alpha tanks are built from virgin polyethylene specifically formulated for potable water contact. This means no off-tastes, no leaching of chemicals, and no degradation from UV exposure or temperature fluctuations.
Frequently Asked Questions
What size fittings should I use with this blank tank?
Most RV fresh water systems use 1/2" or 3/4" NPT fittings. The blank design allows you to drill holes sized for your specific fittings. We recommend using a step drill bit and following proper installation procedures to ensure leak-free connections.
How do I determine if this tank will fit my space?
Measure your available space carefully, accounting for clearance around the tank for fittings and connections. The 385BLANK measures 24" × 15.5" × 10.5", but you'll need additional space for plumbing connections and potential expansion when filled.
Is this tank safe for drinking water?
Absolutely. This tank is manufactured from FDA-approved polyethylene specifically certified for potable water storage. It meets all federal standards for materials that come into contact with drinking water.
Can I use this tank for hot water?
This tank is designed for cold fresh water storage. For hot water applications, you'll need a dedicated water heater tank designed to handle elevated temperatures and pressure.
How long will this tank last?
With proper installation and maintenance, Alpha fresh water tanks typically last 15-20+ years. The seamless construction and UV-resistant polyethylene ensure long-term durability even in harsh conditions.
