What to do if there is excessive back pressure in ZEKS HYDRONIX 20MPS Dehumidifier?
- Rryan72Aug 5, 2025
If the ZEKS Dehumidifier experiences excessive back pressure (above 5 psig) in the regenerating tower, it could be due to a dirty purge muffler that doesn't pass air, in which case you should replace it. Alternatively, it could be that the purge muffler is passing too much air due to a valve leak. In this case, check the Inlet Valve and Outlet Check Valves, and verify that the Inlet Valve is closed to the purging tower (0 psig tower).
