        Comments about 20 Micron Screen Kit for F76S Water Filter:

        Used this unit to replace a disposable sediment filter on a sandpoint shallow well. With the disposable filter the pressure drop was over twice what it is with this unit even when new and by months end (we needed to replace the filter every month) the drop was nearly 5x that of this filter.

        We found that setting the backwash interval to about a quarter of the change interval which we found had worked with the disposable filter to be a good starting point BUT we did replace a 50 micron disposable with this 20 micron unit so that may have some bearing.

        I suggest making sure that you have a pressure gauge before and after the filter and that you monitor the differential and use this to determine the optimal backwash interval for your system. Unlike the 100 micron filter which comes standard with the F76S, with the 20 micron filter long before the filter actually looks dirty you will experience a very significant drop in pressure acrosss the filter (in our case the drop was nearly 20 psi before the fitler looked dirty).

        Since the frequency of backwashing can be fairly high with this filter (compared to the 100 micro filter) I highly recommend installing the MV876B auto backwash controller to automate the process making the system basically maintenance free.

        The only installation warning is not with this filter itself but with the F76S enclosure installation. The included gaskets for the union joints are hard and rather inflexable and hence subject to leaks if the entire assembly is not alligned perfectly. I ended up replacing these with standard flat rubber gaskets which work much better.

        Since these same units are used in places like car washes to remove the dirt so water can be recycled to wash the next car you can be sure that they will be more than able to stand up to heavy use.

          How often do you need to replace the screen kit and what would indicate that it needs to be replaced?

            According to the manufacturer, this depends on the quality of the water and how frequently the filter is backwashed.

          I just installed a Honeywell F76 filter. I cannot find the micron sizing on the filter. How do I find out what size screen is installed.

            F76 filters come with 100 micron screens. Replacement screens are also available in 20, 50, and 200 microns.

            No, all that is included is a relacement O-Ring for the F76S, the 20 micron filter and the plastic adapter for mounting in the F76S (as shown in the picture).
