Nevada, Iowa | Ours is a real old system and when we had to dig it up ten years ago or so, the concrete lid fell apart. I poured a new one and put a stand pipe of 6" pvc in the middle of the new lid. When spring came I finished off the leveling and cut the pipe at ground level and added a screw off cap. We can mow over it and it doesn't get in the way and don't have to dig it up to pump the tank. | |
