Coleman-Mach rooftop AC water or condensate inside
Coleman-Mach installation and Mach 8 condensate-pump instructions point to roof gasket compression, condensate drain hose routing, pump kit drainage, and qualified installation work when water enters the living space.
Owner-safe checklist
- Turn the air conditioner off if water is entering the RV.
- Protect interior surfaces and let ice or condensate drain before another cooling call.
- Record whether the issue follows freeze-up, heavy humidity, rain, or pump-equipped operation.
- Use qualified RV service for roof gasket, condensate pump, drain hose, or rooftop installation corrections.
