Sorry did I miss the septic section? I dont see one. This section looked close based on my problem. Problem: Septic sprinklers don't push as hard as I think they should. Comparing to my neighbors. Details: My Pump tank has a submergible mid intake stainless pump that drives 3 sprinklers in my back yard. Since I moved in the 3 have never really worked well. I replaced all the heads with the purple septic heads and pressure checked the pvc. So there’s not a leak anywhere underground. Inspecting the pump I noticed the pump is down in a pvc tubed there is a 45* cut in the bottom to let water in. However the pump barely fits down the tube so there is not much space to let water so I figured the pump was overtaking the water input. See pic. So looking around online I can't see any reason that green tube is there. There is also a larger tray on the bottom to keep the sludge away from the pump base. Now, I removed the green tube, inspected the pump, looks good. But when I run the sprinkelers without the green tube it spray water out the side. This strips up al the stuff I the bottom of the tank too. So I'm thinking someone put the tub on to control the side jet and band-aid the situation. See video. Should the pump do that?
