          Replacement of T104 timer
          This was super easy to install. All I needed was a Phillips screwdriver and needle nose pliers. I took some photos of the existing wiring. And of course Turn off your power prior to starting

          This is the first time that we have had a timer installed with the water heater. This particular timer was highly recommended by the Home Depot employee helping us. It was highly recommended because of personal use. We have had our new water heater and new timer for a week and we are very happy that we have hot water in the mornings as we all get ready for our day and in the evenings for cooking, dishes, and showers. So far the timers settings meet the needs of our family. It is good to know that if we need to adjust it that we will be able to do that. Very happy so far!

          I commonly encounter these used for controlling On/Off times for pool filter pump applications. Removing the old and installing the new is simply a matter of taking the tension off the clips securing it and slipping it out or in... no tools needed (other than the wiring). They usually prove reliable for at least a couple of years (sometimes much longer) but might eventually fail, the most common problems are worn gears preventing it from keeping time or sometimes the cams wear out preventing it from operating the On/Off trigger switch from functioning. It also has extra holes for mounting in non-standard enclosures if need be (see photos)

            This was any easy fix for my non-working pool pump timer. You just turn off the power to the pump, mark the existing wires, remove the existing wires, pop the old timer out of the case, pop the new timer into the case, re-attach the existing wires to the new timer, set the new timer, and turn on the power. It just requires a phillips screwdriver. There are several YouTube videos available. I don't know what the pool maintenance company would have charged me for this fix, but I know it would have been much more than the fifty-some dollars I spent for the timer at Home Depot.

            Works as described
            Replaced my pool pump timer with this new one. Very simple to install. It just snaps right in and a few wires to connect.
