No need to strain your back and your budget to deal with hard water! Scaltrol water treatment effectively deals with lime (calcium) and other minerals that shorten the life of your dishwasher, water heater, washer, pressure washer and other expensive appliances at your home, farm or business. Scaltrol relies on an advanced, residential/small commercial version of the sequestering process that has been effectively used by municipal water authorities since the 1920's. The Scaltrol unit will not only prevent additional lime and magnesium deposits from forming but will also assist in removing your existing deposits. Basically the minerals are held in suspension and allowed to just harmlessly pass through the water system. Imagine soft towels, no more scaled up showerheads, and appliances not bogged down by mineral deposits. Scaltrol provides this level of treatment without the high cost and potential health issues of conventional salt-based water softeners. Scaltrol is a US company and the product compound is NSF (National Sanitary Foundation) certified, giving you confidence they are safe for your home or business. Models are available to serve from single households to schools and dairies. This model, SC-100, will treat up to 100,000 gallons and will treat the water for a household of 3 or more people for about a year. Individual results will vary with water usage. The SC100 has 3/4" NPT inlet and outlets. A sediment filter such as the Rusco Spin Down sediment Filter (see Amazon listing) is recommended for rural applications with sediment in the water.
