Backwashing whole house filters and water softeners are built to last for years without any regular maintenance; however there are times when a component or part fails to operate correctly or resin/media needs to be replaced. When this happens, it is much easier and less expensive to simply repair or replace a part, or media then purchase a brand new one. Isopure Water sells Fleck and Autotrol control valves and related parts to help fix almost any kind of problem. If you know which part or component of your control valve has malfunctioned, you can choose just that part to replace or the entire valve. There are many parts to a Fleck valves that we carry but may not be listed. Please call (877) 541-6603 for a professional sales representative to assist with your search.
