Jobe Service Kit – Diaphragm Assembly for Topaz & Megaflow Valves | Restore Full Valve Function

The Jobe Service Kit (Diaphragm Assembly) is the genuine rebuild kit for Jobe Topaz and Megaflow float valves. When your valve starts leaking, dripping, or failing to shut off properly, the diaphragm is almost always the culprit — and this kit gives you everything you need to restore full valve function without buying a brand new valve.

The diaphragm is the heart of the Jobe valve mechanism. It flexes with every fill cycle, and over time it wears, cracks, or loses its seal. When that happens, the valve can’t shut off cleanly — leading to overflow, wasted water, and a trough that never quite fills right. This service kit replaces the diaphragm assembly with a genuine Jobe part, restoring the positive shut-off and reliable performance the valve was designed to deliver.

Compatible with both the Topaz and Megaflow series, this kit is the smart, cost-effective alternative to full valve replacement. Keep one on hand and you’ll be able to service your valves on the spot, wherever they are on your property.
