Pentair Drain Cap | Sand Dollar, Cristal-Flo II & More | 154712Z

Description

The Pentair Drain Cap (154712Z) is the OEM replacement drain cap for Pentair Sand Dollar, Cristal-Flo II, SEP Separation Tank, Clean & Clear RP, POSI-CLEAR RP, and System:2 filter equipment.

IMPORTANT: MODEL YEAR COMPATIBILITY — CRISTAL-FLO II
For Cristal-Flo II filter systems, part number 154712Z applies to units manufactured 2009 and beyond. Verify your unit’s manufacture date before ordering if you have an earlier Cristal-Flo II system.

The drain cap seals the tank drain port, maintaining a watertight closure during normal filtration and allowing the tank to be drained for service or winterization. A cracked, stripped, or otherwise failed cap results in water loss at the drain port and an inability to hold system pressure. This direct-fit OEM replacement ensures correct thread engagement and seal geometry matched to the original tank specification.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Poolaroo Pro Tip

Before ordering, locate part number 154712Z on your existing cap — it will be molded or stamped into the plastic — or confirm it via your filter’s exploded parts diagram using your tank model number. Drain cap thread dimensions and port geometry vary across Pentair filter families, and visual similarity alone is not a reliable match. If you are replacing the cap as part of seasonal winterization or spring startup, inspect the cap’s sealing surfaces and any associated O-ring for wear at the same time. Consult your filter’s installation manual for the correct torque specification on reinstallation.
