They Came Out the Very Next Day!

I called last Thursday, mid afternoon, they were there Friday to inspect and back that afternoon to replace our exterior faucet that had been leaking. It looks great, and they gave us some feed back on a couple other issues we were having. Pricing was far better than other quotes we received. Would recommend if you’re not a plumber yourself and need professional guys to come out and help you.

Water Softeners

Sales, Installation, Service, Repair & Rental

An authorized Hellenbrand dealer, Hess Bros./Derby Water Conditioning sells, installs and services Hellenbrand water conditioning equipment.

Hellenbrand leads the industry with water softening systems that are designed, assembled and tested in the USA. Family owned and operated since 1967, Hellenbrand has helped customers see water clearly for nearly 50 years.

Treated water has many benefits in your home, including healthier skin and hair, greater efficiency of appliances, improved cleaning power of soap and detergents, and extended life for appliances and fixtures.

Softener size is determined by consumption and the hardness of your water. Other factors to consider include bacteria or iron which may alter the treatment method.

Call (316) 777-1661 to schedule a consultation to determine your water treatment options!

Water Softener Service & Repair

Hess Bros./Derby Water Conditioning services and repairs numerous makes and models of water conditioners. We have years of experience diagnosing existing softeners to repair or rebuild an older unit so it works like new again. (We also offer water softener rentals.)

Reverse Osmosis Drinking Systems

Sales, Installation, Service & Rental

Hess Bros./Derby Water Conditioning sells, installs and services Hellenbrand reverse osmosis drinking systems.

The Millennium Reverse Osmosis Unit by Hellenbrand is our proven system of choice for purified drinking water. This reverse osmosis system removes 99% of all mineral and chemical contaminants from your tap water. This drinking system gives you the quality of bottled water at the convenience of your kitchen sink.

Unlike most home tap or refrigerator filters that only use one taste and odor filter, this reverse osmosis system uses four stages of filtration to not only remove sediments, taste, and odor but also the majority of other impurities including chlorine, sodium, nitrates, bacteria, arsenic fluoride, barium, calcium, chloride, and detergents.

The Millennium Reverse Osmosis System comes with professional installation and a set of filters for the first year. Filter changes are recommended once a year to maintain the purity of water.

Reverse Osmosis Drinking System Service

Hess Bros./Derby Water Conditioning also services reverse osmosis drinking systems by most other manufacturers. Changing reverse osmosis filters annually ensures purity of water and efficiency of the system. Hess Bros and Derby Water Conditioning will change your filters, test your water, and provide any needed maintenance to keep your unit running as it should. We also sell filters at our office or can ship them at your convenience.

Reverse Osmosis Drinking System Rental

For as low as $20 per month, rent a reverse osmosis and have purified drinking water at your kitchen sink! No more water bottles, filling up jugs or settling for low quality water. When you rent a Reverse Osmosis System, you will get professional  yearly maintenance at no cost to you, a value of $146 a year.

Call (316) 777-1661 for safer drinking water!

Iron Filtration, Carbon Filters & Other Water Treatment Systems

Contaminants cause many problems in water supplies. Iron stains laundry, dishes, sinks, tubs and showers yellow or brown. Iron also accumulates and clogs dishwashers, washing machines, sprinklers, wells, water pumps and other appliances and accessories, requiring expensive repairs. Iron also affects the taste of beverages and food. Iron adds a bad taste and an unpleasant, inky blackness to water and drinks made with water. Food, especially vegetables, cooked in water containing iron turns unappetizingly dark and absorbs iron's unsavory taste.

Hess Bros/Derby Water Conditioning and Hellenbrand offer several filter solutions for common contamination problems.

  • Iron Curtain:  One of the most reliable iron and sulfur (rotten egg odor) removal systems.
  • CLC Filter: This is a whole house filter tank that uses a bed of carbon to remove taste and odor. Maintenance free!
  • STORM: Uses Ozone as the oxidizer for iron, sulfur, and nuisance bacteria. This is a chemical free option to remove iron, iron bacteria, sulfur, and manganese.
  • Whole House Filter: With either a carbon or sediment filter this provides a simple water filter at your homes point of entry. This does require filter changes and is recommended in front of most softeners.

Call Hess Bros/Derby Water Conditioning at (316) 777-1661 for contaminant-free water!
