Overview

The Orbit WaterMaster Underground diaphragm repair kit is designed to refresh worn or damaged diaphragms in Orbit automatic bleed valves. Supplied as a 2-pack, it provides spare diaphragms to help keep irrigation or water control systems operating with less downtime. The diaphragms are built for durability and long-term reliability, supporting routine maintenance without needing a full valve replacement.

Compatibility and what is included

The kit targets Orbit internal bleed valves used in WaterMaster installations, fitting 3/4-inch valves (57100) and 1-inch valves (57101). With two diaphragms in each pack, you have a ready-to-use spare for future maintenance.

  • Replacement diaphragms designed to fit the Orbit automatic bleed valves mentioned above.
  • Two diaphragms per kit for easy, on-hand replacements.

Real-world use and benefits

Install during routine maintenance or when you notice changes in valve responsiveness. While results can vary by system, users often report smoother valve operation and reduced risk of leaks after a diaphragms upgrade. This kit offers a practical way to refresh aging components without full valve replacement.

  • Supports easier maintenance and potentially longer valve life.
  • Cost-effective option compared to replacing entire valve assemblies.

Installation tips

Before starting, turn off the water supply and depressurize the line. Remove the existing diaphragm, install the new one, and reassemble. If in doubt, consult Orbit manuals or a professional for guidance.
