Does the System require electricity?

Filtration is accomplished with existing water pressure and no electricity is required to filter your water. Unless required for pump operation, the System will continue to filter water during a power failure. Electrical power is required to operate the automated drain and inlet (solenoid) valves that initiate automatic flushing of the System. If electrical power is not available the System will not conduct automatic flushing. Controller settings are saved by battery backup power.

Does the System affect the water pressure?

There is minimal effect on your existing water pressure. Under most circumstances, no change in water pressure will be noticed after the installation of a new System. There is no need for an additional water pump if the existing water pressure meets the minimum System requirements. Under normal operation in cloudy water the System may foul more quickly than in cleaner water, may require more frequent cleanings and may require alternate controller settings.

What can be done to increase my water pressure?

Table 5 outlines four reasons why your pressure may be lower than normal. Check as many as possible before calling MAYTAG Customer Care.

How long does the System last?

The System will generally last over 10 years if used on municipal water and will last from 5 to 10 years on surface/lake waters depending on the level of contamination in the incoming water.

What do I need to do if I go away for an extended period of time?

If you wish to shut off the water supply to your house while you are away you may simply close the outlet ball valve on the MAYTAG Whole Home Water Filtration System. The MAYTAG Whole Home Water Filtration System will continue to flush daily but water will be unavailable in the house.
