Opportunity to test a water softener blending valve and get it free!
Our District has partnered with the City of Middleton on a program to reduce salt from water softeners. We are looking for Middleton residents to help test blending valves, plumbing devices that adjust the level of hardness in your home’s water. By installing a blending valve on your water softener as part of this free program, you’ll reduce the water you soften, saving you salt and helping protect downstream waters from excessive chloride.

Who’s eligible?
Free blending valves and installation will be provided first-come, first-serve while supplies last to residents who meet all these criteria:
• Resident of City of Middleton
• Own your home
• Have a working water softener compatible with the blending valve used in this project
• Willing to share information about your experience with the District after a two-month test period
To apply
Find out if you’re eligible and apply for the program by filling out this online survey. Only 48 blending valve packages are available as part of this limited-term program, so act fast!
Learn more about blending valves, how they work and what they do to save salt in the environment on the Blending Valves page of our website or read the article “Soften water with less salt using blending valves” on our blog.
