This kit aims to simplify on-site repairs, helping maintain steady water flow in irrigation or building systems without requiring a full replacement of the unit.\u003c\/p\u003e\n\u003cp\u003eBuilt to address common failure points caused by oxidation, wear, and age, the 720A kit consolidates the essential bonnet components, seals, and internal parts into a single package. The result is a more predictable maintenance experience, with a clear path to restoring function and reducing the nuisance of leaks. While the kit is designed for broad compatibility, it is best viewed as a comprehensive solution for most 720A PVBs, rather than a universal fix for every possible failure.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBonnet washers and bonnet O-rings\u003c\/li\u003e\n  \u003cli\u003eLoad nuts and rails, plus load washers\u003c\/li\u003e\n  \u003cli\u003eTop plates and canopy screws\u003c\/li\u003e\n  \u003cli\u003ePoppet valves and springs\u003c\/li\u003e\n  \u003cli\u003eGuide spiders, hex nuts, and related small screws\u003c\/li\u003e\n  \u003cli\u003eOne canopy, one bonnet, bonnet gasket, and bonnet O-ring\u003c\/li\u003e\n  \u003cli\u003eAdditional internal components for a complete rebuild\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility and coverage\u003c\/h3\u003e\n\u003cp\u003eThe kit targets Zurn Wilkins 720A assemblies in 1\/2–2 inch sizes and aligns with the RK1-720AB 1\/2\"–2\" 720A PVB assemblies.
