Bring out the bypass valves from storage when you want to back flush. Just turn the flow off at the double valves, disconnect them, connect the single valves, then turn them all on. You simply put a bucket under the waste water vent hose and switch 3 valves. This reverses the flow through the filter.
Once a month during your regular maintenance routine just back flush the system for about 30 seconds or so. This should be sufficient to loosen up the bio media and wash through any detritus or organic build up trapped. After you have achieved the desired affect, switch the valves back and the filter runs normally.
