2 Suction pipes

[Drougo]

Hi, I have an inground concrete pool which is quite large (approx 80,000ltrs). I have a normal skimmer basket with my G2 cleaner attached to it but have recently realised that there is a second suciton point. It sits halfway down the length of the pool and at about half the depth of that section. It juts out from the surface and has a screw thread on the outside (so it is a male part). When the cleaner is attached to the skimmer box it has a huge amount of suction and when the cleaner is not attached to the skimmer it has very little suction. I think it is stopping my cleaner from working properly.

Does anyone know what this pipe is for and what I can do about it. I think it poses quite a danger to long hair and children?!?

It sounds extremely dangerous. I would have a pro come out and see what can be done.

Thanks I will do. It certainly seems really dangerous and I would hate to be the reason for injuring someone or worse...
