Min Tnk, 10x44 Natural Poly Glass

The Pentair 10" x 44" Natural Poly Glass Mineral Tank (alternate part PT1044-A) is a high-capacity residential and light-commercial vessel widely used in water softeners and whole-house filtration. The 10" x 44" format is among the most popular larger tank sizes, offering generous media volume in a footprint that still fits comfortably in a typical utility space—a sweet spot that has made it a staple of countless installations.

A proven size

The 10-inch diameter holds substantially more resin or media than narrower tanks, delivering higher service flow rates and longer runs between regenerations—ideal for larger households or homes with demanding source water. The 44-inch height keeps the overall package compact enough for most garages, basements, and mechanical rooms without crowding. Construction is natural-finish poly glass: a fiberglass-reinforced shell over a seamless inner liner that resists corrosion from the water on the inside and the humidity on the outside, with no risk of rust flaking into the treated water over the years.

• 10" diameter x 44" height—a popular high-capacity size
• Natural-finish poly glass (fiberglass-reinforced) construction
• Seamless, corrosion-resistant inner liner
• Holds softening resin, carbon, or specialty media
• Approximately 12.03 lb empty weight
• Genuine Pentair mineral tank (alt. PT1044-A)

As a genuine Pentair tank, the 10" x 44" vessel mates cleanly with the standard control valves and distributor tubes sized for its opening, integrating reliably into both residential and light-commercial builds. Use it for a whole-house carbon filter, a high-capacity softener, an iron filter, or a custom specialty-media application—the size handles them all with room to spare. The taller 44-inch profile also lends itself to media that benefit from extra bed depth and contact time, since water spends slightly longer in the column before reaching the outlet. Whether you're building a new system, upgrading from a smaller tank that has been outgrown, or replacing one that has aged out, this 10" x 44" poly glass mineral tank gives you a durable, high-capacity foundation trusted across a great many installations. Complete it with the appropriate valve, distributor, and media, and remember to leave proper freeboard so the bed can expand during backwash without losing media to the drain. A bottom layer of support gravel is often added to spread flow across the base screen and shield the distributor from finer media particles.
