Last week we did our annual inspection of our Amiad filter in our pump station. This filter cleans the irrigation water with a 300 micron screen that is self cleaning with internal brushes. The filter runs several times during a irrigation cycle keeping contaminates form entering the system. Thankfully we only have to to inspect this filter every 5 years because of the weight and size of the filter. When we designed the pump station we purposely built 12 foot tall ceilings so we can remove the top of the filter and the internal screen, as you can see from the picture below the filter is seven feet tall. To remove the top of the filter we added a small pulley to the ceiling and attached the top of the filter with steel cables and a come-along so we could lift off the top of the filter more easily. Our inspection of the filter and brushes was encouraging, only a slight cleaning of both. After re-assembling the filter we charged the station back up to check for leaks, so far so good, no leeks and the filter is running properly.
