Bypassing the MAYTAG Whole Home Water Filtration System will result in unfiltered water entering the household distribution system. This water may be biologically unsafe and drinking this water could result in illness or death. Exercise caution in bypassing the System. Do not drink water from the System while the System is in bypass mode.

If the System has been operated in bypass mode and if water is being drawn from a well or surface water source, the household distribution system should be re-disinfected once returned to filtration mode.

If the System is in bypass mode, the controller must be unplugged. Failure to do so may cause System to dry and become damaged, which may lead to personal injury, and/or physical damage and will void any warranty.

A bypass system is not required for proper operation of the MAYTAG Whole Home Water Filtration System, however some local plumbing codes may require a bypass. If the System is to be equipped with a bypass, the procedure below may be followed to provide water in an emergency or System malfunction.1
