CountryB Posted May 1, 2023 Share Posted May 1, 2023 Just curious about how the "Air Dump" system works on Coaches with the HWH air leveling system. Does the air dump though the HWH manifold, or is there a separate dump valve? I don't have any wiring diagrams, or air schematic diagrams, showing how the dump system works. My HWH control panel has a "dump" button - but I also have a separate Air Dump rocker switch next to the HWH panel. Are both switches acting on the same valve (HWH valves)?
