My system, which is what came with the house, is a 3 HP pump that has a "Screen" to keep out fish, my fingers can get in...the intake is 2" and output 1.5" sch 40 that runs 15 feet to the yard with a section of some sort of black flexible hose to accomidate lake level changes (can be as much a 5'). On the pvc section over the lake and at the lowest point I put in a drain so I could drain by gravity, in the fall. (Elevation change is about 30') The 1.5" pipoe enters the lawn through the "sea wall" and I have no clue about the layout. Where do I put a filter. Is this a yearly or weekly cleaning job. I run the sprinklers for about 4 hours one time a week to get a deep soak in heavy clay.. Adonika
