The GMX water softener system is designed to eliminate scale build-up in your pipes and appliances, make cleaning much easier, and soaps lather better. See all the features and benefits of using the GMX system in your home: GMX Water Softener - Features and Benefits.

The GMX Water Softener System is not designed to filter your water. A Water Filter System may be added if you are concerned about the contaminates in your drinking water. The GMX Devices are designed to replace the salt based unit only, not the reverse osmosis unit that removes the salt from your drinking water. A reverse osmosis unit is not needed with GMX.

With GMX there is no maintenance and no salt. The GMX System also comes with a Lifetime Warranty. GMX is the last water softener you will ever have to purchase and is unlike any other systems on the market today.

Select your GMX system based on:

• WATER HARDNESS
• QUANTITY OF WATER HEATERS

Incoming Cold Water is treated with either:
two -or- three GMX devices
(depending on water hardness)

Outgoing Hot Water is treated with:
two GMX devices
(for each water heater in your home)

In Summary:
Two GMX devices are placed over the main incoming cold water line if your water hardness is less than 17 grains (300 ppm). And three devices, if your water hardness exceeds 17 grains.

• You must use two devices to treat the hot water as it leaves your water heater. All homes need a minimum of the GMX 4800 Home System. This system is considered our "Standard Household System" and is purchased by about 55% of our customers.
  
  Homes, with 2 water heaters or water hardness over 17 grains will require a larger system.

• If your water hardness exceeds 17 grains (300 ppm), your must treat your incoming cold water with three devices you will also need two devices for each of your water heaters. This includes homes with "on demand" or "tankless" water heaters. Your home will need either the GMX-5800 with one water heater, or the GMX-7800 with 2 water heaters.

You can always step up to a larger GMX System, but you cannot step down (and expect positive results).
