Min Tnk, 10x54 Nat. Poly w/Dm Hl & Plug

The Pentair 10" x 54" Natural Polyglass Mineral Tank with Dome Hole and Plug (alternate part PT1054-ADH) is a high-capacity vessel for larger residential and light-commercial water-treatment systems. The 10" x 54" size is one of the larger standard formats, and this particular version adds a top dome hole with plug—a thoughtful feature that makes media loading and tank servicing notably easier than on a single-port tank.

The dome-hole advantage

The dome hole, located at position A, is a secondary opening in the top of the tank, sealed with a plug, that gives installers convenient access for adding or topping off media without fully disassembling the control valve and main riser connection. On a tall 54-inch tank, that access is a genuine time-saver during both commissioning and later maintenance. The tank's natural-finish polyglass construction—a fiberglass-reinforced shell over a seamless inner liner—keeps it corrosion-resistant inside and out, protecting both the vessel and the treated water throughout its service life.

• 10" diameter x 54" height—a large high-capacity size
• Dome hole with plug (Location A) for easier media access
• Natural-finish polyglass (fiberglass-reinforced) construction
• Seamless, corrosion-resistant inner liner
• Approximately 16.2 lb empty weight
• Genuine Pentair mineral tank (alt. PT1054-ADH)

The tall 54-inch height combined with the 10-inch diameter gives this tank a large media volume, delivering high service flow rates and long runs between regenerations or backwashes—well suited to larger homes, demanding source water, and small commercial uses. The taller bed also leaves ample freeboard above the media, which is exactly what a backwashing filter needs so the bed can lift, expand, and rinse out trapped sediment fully. That extra height also tends to improve the contact time between the water and the media as it travels down through the deeper bed, which can sharpen reduction performance on filters that depend on dwell time. As a genuine Pentair tank, it pairs cleanly with the standard control valves and distributor tubes sized for its opening. Whether you're building a high-capacity whole-house filter, a large softener, or an iron-reduction system, this 10" x 54" dome-hole polyglass tank offers durable construction plus the practical serviceability that the dome access provides during media changes. Complete it with the appropriate valve, distributor, and media for a robust, easily maintained treatment system.
