Hague’s WaterMax is the world’s most efficient residential water treatment system!   Click here to download a Brochure!

Hague has been awarded 9 US Patents with more pending. These patents went into designing the WaterMax whole-home water treatment system. Combined with the Hague H3500 R.O. unit, forms the MaxPack!  

Uses the least amount of water to regenerate / back-wash than any other residential system (recharges and cleans the resin bed). 

Depending on the computer setting it regenerates (cleans itself) in as little as 17 min using as little as 16 – 49 gallons of water. 75 gallons is considered moderate efficiency. 100 gallons is not uncommon for conventional softeners.

The tank is the only tank designed specifically for domestic water treatment. The outer polycarbonate shell is mold, mildew and UV resistant. The light color reflects incoming solar radiation avoiding heat transfer to the tank itself. The treatment vessel is never exposed to light or heat.

Extended 10 year warranty on electrical and moving parts with a standard 25 year warranty on valve body, resin beds and tanks.
Our computerized controller runs on 14 watts 12 volt AC at a cost of approximately .03 cents per month.

It uses less salt than any other system during regeneration. As much as 5,900 grains of compensated hardness can be removed with only 1.1 pounds of salt.

The H3500 Reverse Osmosis System is 300 times more efficient than conventional R.O.s.

Uses between 1.8 to 3 gallons to make 1 gallon of  life support drinking & cooking water, compared to an average of 8 to 12 gallons to make one gallon.

Provides 24 gallons of highest quality life support drinking water a day at 72 degrees.

WaterMax regenerates on demand, by calendar or by exact water usage. The flexibility of the solid state System Control makes it possible. A 12-volt low voltage power supply powers the Systems Control.
