Min Tnk, 10x47 Grey Poly Glas-Disc

The Pentair 10" x 47" grey Poly Glass mineral tank offers a slightly taller profile than the standard 10x44, providing a bit of extra media capacity within nearly the same diameter and floor footprint. Note that this particular size has been discontinued by Pentair, which makes available stock especially valuable for matching existing equipment or replacing an aging 10x47 column without having to redesign a system around a different tank size. For installers maintaining systems originally built on this dimension, finding a true match can save considerable rework.

Why the taller tank matters

The added three inches of height accommodate a larger media bed, which can extend service runs between regenerations or backwashes and boost overall capacity for both softening and filtration—all without widening the system's footprint or requiring more floor space. Like every Poly Glass vessel, it is built by winding fiberglass over a seamless inner liner for strong, corrosion-resistant performance and a chemically inert interior that will not affect the chemistry of the treated water passing through it. That inert construction makes it suitable for resin, carbon, or specialty media alike.

• Nominal 10" diameter by 47" height
• Cool gray Poly Glass (fiberglass-wound) construction
• Discontinued Pentair size, ideal for direct replacements
• Empty weight approximately 13.0 lbs
• Corrosion-resistant with an inert inner liner
• Accepts standard control valves and distributor assemblies

To complete a system, pair the tank with a compatible top-mount valve, the correct distributor and riser tube, and your selected media. Always verify thread and distributor compatibility before assembly, and respect the manufacturer's pressure and temperature limits during installation and operation. Because this is a discontinued dimension, securing a tank now is a smart move for anyone who anticipates needing to maintain or expand a 10x47-based system in the future, when replacements may become harder to find. For installers who specifically need the 10x47 form factor that is no longer in regular production, this tank is a practical and increasingly scarce option worth securing while it remains available. Securing one now is a prudent step for anyone responsible for keeping a 10x47-based system running smoothly well into the future, long after new stock disappears.
