7.5 What can be done to increase my water pressure?

Table 7.1 outlines four reasons why water pressure may be lower than normal.

Table 7.1 – Possible causes of low water pressure

Problem Solution

The External Prefilter Cartridge (if installed) is

fouled.

Change the prefilter cartridge.

The Internal Prefilter (Carbon or Stainless

Steel) is fouled.

Clean or change the prefilter.

The city / pump pressure is low or the line is

scaled.

Call the city or check the pump.

The MAYTAG Whole Home Water Filtration

System is fouled.

Initiate Manual Flush Function. If this does not resolve the low-

pressure situation, arrange for possible System replacement.

7.6 How often does the MAYTAG Whole Home Water Filtration System

need to be replaced?

The System is designed to last the life of the membrane, with regular maintenance.

7.7 How long does the MAYTAG Whole Home Water Filtration 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.

7.8 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. If you plan to turn

off the inlet ball valve (not recommended), you must unplug the controller. When you return open the

outlet ball valve (and unsure inlet ball valve is open and 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.

7.9 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. See section 2.6 for Bypass Instructions and warning.
