About This Product

Q:What is the gpf for this model?
by|Feb 24, 2020
1 Answer
Answer This Question

A:  The gpf is determined by the diaphragm in the flushometer, not by the Zurn EZ Flush. This will work on all 4.5, 3.5, 1.6, 1.28, 1.0, and 0.8 gpf Sloan and Zurn flushometers.

    Q:will this install right where the manual handle goes

    Answer This Question

    A:  Yes you remove the original handle with a wrench. Then the auto flush comes with the proper washer and a special wrench to install. Very very simple. Don’t forget to turn of the water supply first.

      A:  Yes, but keep the manual handle on site in case the EZ Flush fails, which is rare.

          Easy to install, wrench provided
          Replacing an old auto flusher is easy. Zurn also provides a wrench. There are videos available for installation if needed.

          We should have done these years ago!
          This was the easiest retro-fit I have ever done. Literally less than 10 minutes for each one. They are working perfectly and the bathroom smells MUCH better.

          While these work pretty well to allow you to operate hands free - the only down side is these tend to die rather quickly in a high volume place

            Quick and easy install with clear instructions and all necessary tools included in the package. You don't have to turn your water off but it is always a good idea when working on plumbing with live lines. (pressurized)
