Used a filter in a well for a home irrigation system. The well is about 30 feet deep and I'm in the Bay Area. The filter works great, but clogs after about a month. Even when opening the valve in the housing that should clean the filter, it doesn't really work. I had to manually clean the filter, which was quick and easy, but painful as I had to do this every three to four weeks or there wouldn't be enough pressure in my system to keep the sprinklers working. The filter only lasted about 6 months, I tried hand cleaning and used a brush but it was still so clogged I had to remove it to make sure the sprinklers had enough pressure to work. Apart from having to check it from time to time, this worked great. I just wish they were about twice the size.
