So if anybody had ready my other threads we recently took over this job from our PB due to several issues, everything is actuallly going quite smoothly so far, now I’m trying make sure everything is here and correct. One thing I’m unsure about those is that the are 4 2” pipes piped into the pool lowere than the regular returns. Does anybody have a suggestion as to what these are for and how they should be capped?
 
I have a waterfall/slide that runs off a separate pump. It uses a dual-suction system as an anti-entrapment measure on the lower pool wall. The main drain on the floor is the same, a split suction with two connected drains. If you have any water features that run off a separate pump or suction source, they should have dual intakes.

I'm not sure how they are installed, but the cover itself needs to mount to some type of a wall adapter. Maybe a couple photos as Joyful Noise suggested will help.

:bump:Bump for some more help.
 
I’m haveing trouble loading the pic, but it definitely is the suction for the waterfall and bubbler pumps, and it definitely is 2”. So what do I do now?

I think something like these 2" suction fittings and covers are what you're looking for. This is just one example, there are other sizes/types/colors.

The one in the link is a 2" inside slip connection, but they carry threaded versions as well if your pipes have threaded fittings at the wall.

Just to give an update and closure to this thread, so others will be aware, the pool got plastered today and the plaster company said I don’t need the special 2” pieces. They use the standard 8” drain cover, and when the plaster, they plaster the mounting frame into the plaster. So what I thought was problem actually wasn’t. Thank you for everyone’s help.
