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 is plugged in) and household pressure will be restored. It is recommended that you also turn each tap on for 10 minutes to flush out stagnant water before use. How do I bypass the MAYTAG Whole Home Water Filtration System? Bypassing the MAYTAG Whole Home Water Filtration System is not recommended unless there is an Emergency and your MAYTAG Whole Home Water Filtration System is not working properly. Contaminated water may enter your home, which can cause serious health problems, even death.
How long does the Carbon Prefilter last? The Activated Carbon Prefilters are designed to filter over 100,000 US gallons (378,000 L). The average homeowner will find it necessary to change the activated carbon filter every 9-12 months. The quality of water, amount of chlorine, other contaminants in the water (chlorine), and the amount of water used determines the actual life of an activated carbon filter.
My lake water is quite dirty and the External Prefilter Cartridge requires replacement quite often. Can I increase the time between replacements of the External Prefilter Cartridge? Yes. In some cases two External Prefilters have been installed. With two External Prefilters, the time to replace the External Prefilter Cartridge is extended by more than twice the original time.
