We purchase our water softener and filtration equipment through Duff and install it for our customers homes. The products have been great and their team is always easy to work with. We’ve had a great experience working with Duff and appreciate the partnership!

Had a Duff WS1 control valved installed a couple years ago. The manual had Duff all over it. Noticed an E1 code and my plumber came out and reset the unit and code went away. He said he would reach out to Duff since the Duff manual didn't go into any details. After a regen, water continued to drain. Couldn't get a hold of our plumber so emailed Duff with error code, continual drain and any local repair companies in the area. Couple hours later received a reply to contact a company about 70 miles away. No possible solutions or what the error code could be. Went on YouTube and searched for Duff control valves. Clack came up in the search. Looked exactly like mine and watched a couple videos and fixed it for less than $100. Am guessing it's a Clack control valve rebranded as a Duff since the parts needed were Clack part numbers. Also found a more detailed manual on the Clack website.
