Davey - Crystal Clear Air Bleed Screw Kit - Q2033SP

Davey – Crystal Clear Air Bleed Screw Kit (Q2033SP)

The Davey Q2033SP is a genuine replacement air bleed screw kit designed for Davey Crystal Clear, Easy Clear, EcoPure, Clearflow, CF-series, and Series 100 cartridge filters. The air bleed screw allows trapped air to be purged from the filter housing, preventing airlock and ensuring the pump and filter operate efficiently. This kit includes two air bleed valves — one fine-thread and one coarse-thread — plus one O-ring, making it a practical universal solution for the full range of compatible filters.

Compatibility

This kit fits a wide range of Davey and Spa-Quip cartridge filters, including the Crystal Clear, Easy Clear (all sizes), CF50 through CF2250, EcoPure, Clearflow, and Series 100 models. Because Davey used both thread sizes across different production runs of the same filter models, the dual-bleed design of this kit removes all guesswork — simply install the screw that matches your filter’s thread. Always confirm which thread size your specific filter requires before installation.

Why Genuine Matters

As an OEM Davey spare part, Q2033SP is manufactured to the exact tolerances of the original component, ensuring a reliable, leak-free seal. The included O-ring is matched to the housing seat dimensions, providing a proper pressure-tight fit. Aftermarket substitutes may not achieve the same thread engagement or O-ring seating, risking air ingress or leaks at the filter lid.

Installation

Hand-tighten the correct air bleed screw into the filter lid port, then snug it up with a small spanner — do not overtighten. To bleed air, briefly loosen the screw with the pump running until a steady stream of water (not air) appears, then re-tighten. Replace the O-ring at the same time to restore a positive seal. If the filter is repeatedly requiring air bleeding, investigate whether the system has an air ingestion issue upstream.
