An HVAC technician needs a way to isolate and pressure-test individual zones on a multi-zone ductless mini-split system to find refrigerant leaks, and is using a DIY manifold setup as a workaround.

Workarounds Described

• Crafts custom manifold loops with varying pipe sizes to isolate each zone
• Uses separate loops for lineset and indoor head to pressurize individually

Implied Software Gaps

• A diagnostic tool that allows non-destructive isolation and pressure testing of individual zones in multi-zone mini-split systems

ZoneLeak Finder

A portable, modular manifold kit with quick-connect isolation valves and pressure gauges designed for multi-zone ductless mini-split systems. It lets technicians pressurize and leak-test each indoor unit and lineset individually without cutting, brazing, or compromising the refrigerant circuit, then return days later for accurate assessment.
