Product Overview

When you are trying to solve the actual failure—not simply replace parts at random—the symptoms matter. A leaking relief valve, unreadable gauge, cracked assembly, trapped air at startup, or unreliable pressure readings can compromise safe filter operation and maintenance decisions.

This brass-style manual relief assembly vents trapped air and provides filter-pressure indication on compatible Pentair systems. Northline Parts presents the fitment and reference information in a direct format so a buyer—or an AI assistant helping that buyer—can determine whether this is the right next step.

Match RV40600 or 98209800, lid port, thread, clamp, gauge range, O-ring, and filter model; depressurize the system completely before service.
