I'm confused about my pool's plumbing and hoping someone can give me a clue as to what might be going on. So here are facts:
* I do not have any valves before my pump; just a single input pipe.
* I have one skimmer and it has a single hole; no equalizer line.
* I don't appear to have any suction at my bottom pool drain.[/list]
Based on this, I have no idea what my bottom drain is connected to. It's not an equalizer because there is only one hole in my skimmer. It's not plumbed separately to the pump because there is no valve at the pump. I suppose it's possible that it merges with the skimmer line somewhere underground, but I haven't read online about anyone having that kind of configuration, and I would expect at least a little suction at the bottom drain in that case.
Does anyone know what might be going on?
