About This Item
The Pentair Systems Base (155333P) is the OEM replacement base for aboveground filter systems in the Sand Dollar, Cristal-Flo II, EasyClean, Clean & Clear, and PLD Series lines — including configurations paired with the OptiFlo pump.
⚠️ IMPORTANT: CONFIRM YOUR SYSTEM SERIES AND MANUFACTURE DATE
Cristal-Flo II and Clean & Clear compatibility applies to systems manufactured 2009 and beyond. PLD Series compatibility applies to systems manufactured 2009 and beyond with the OptiFlo pump configuration. Verify your system's series and manufacture date before ordering.
The systems base is the structural foundation of the filter system assembly, mounting the filter tank and pump to a unified platform. A cracked, broken, or degraded base compromises the stability of the entire filter-pump assembly. Replacing the base with the correct OEM part restores the structural integrity of the system. Match the part number 155333P to your existing base before ordering — base geometry varies across filter series and is not interchangeable between system families.

Pro Tip
Before ordering, locate the model number label on your existing filter system — typically found on the tank body or base itself — and confirm it matches one of the compatible models listed above. Base geometry is series-specific: a Sand Dollar base is not interchangeable with a Cristal-Flo II or PLD base even when they appear visually similar. If your system is a Cristal-Flo II, Clean & Clear, or PLD unit, also confirm it was manufactured in 2009 or later, as earlier versions used a different base design.
