Description

The Pentair Style 1 Internal 9/16″ Orifice (White) SKU 236151 is an ideal service part for maintaining or restoring performance in in‑floor cleaning systems built around the Style 1 head. With the 9/16″ orifice engineered to match original cleaning specifications, this cartridge provides the right flow and alignment to restore full system coverage. It’s particularly useful during resurfacing or when your cleaning head shows signs of wear—but the housing remains intact.

Pro Tip

Before installation, shut off the system and relieve pressure. Check the internal housing and riser for wear or damage; if found, consider upgrading the head body at the same time. Clean and clear the riser, then drop in this cartridge and restore operation.

Installation Tips

Turn off pool circulation system and relieve pressure prior to servicing. Confirm the head assembly aligns with Style 1 system and the riser pipe is appropriate. Insert this cartridge flush into the housing, verify head rotation clearance, and then restore system operation.
