I am putting a new assembly in today with o ring. What is the proper placement for the flo control trimmer plate to be in ? I am sure sure impact of being wide open , fully closed or somewhere in between. I have a suction vac that has its own intake port on the pool wall - I do want to have the skimmers removing tps stuff while the vac is hitting the bottom. I have 2 holes below skimmer and and two main drains in the pool. I have about 50/50 on the skimmer / drain suction to the pump right now -
thanks
 
I adjusted mine so that I just see a difference in the turbulence in the skimmer. But if you have a cleaner going, you could shut the main drain off completely, because it will do a good job of mixing the water and preventing temperature stratification. The main drain tends to be pretty useless.

So I am clear as this sounds like 2 things your suggesting
1. Adjust to see water movement - Is that opening more like maybe wide open or 1/4 closed only ?
2. Shutting of the main - Is that only when using the vac or all the time ?

I have a variable speed pump so on low speed for about 5 hours the vac is still or maybe the wings move a bit / In high speed the vac moves around for the 4 to 5 hours - I run an hour per 10 Degrees temp outside

Just shut the main drain off if you run the vacuum 5 hours a day. It'll do a better job than the main drain could do all day long.

And so I am clear, maybe you better explain your plumbing. I'm guessing you have one valve to control the vacuum and another to the skimmer which also is connected to the main drain.

Yes , one valve heading to the pump that I can either close the sweep or close the drain. I hope that is what your asking - I normally keep it 50 / 50 so it is pulling from the main drains ( I have 2 ) & the sweeper, which connects at the opposite side of the pool , in the pool wall . I normally keep the pool vac in all the time. I know the mains work as I used them 100% when I was clearing the plaster dust after the new plaster job was completed a few weeks back - I have attached a pic of the line I am speaking of and the little flo control thing I was asking about too 20200516_120150B.jpg20200516_120221B.jpg

I would set the valves so the vacuum gets enough suction to run reliably and the rest goes to skimmer. Just leave that diverter set wide open. It's opposite what you might think. Here's how that diverter works.

Thanks - Had to watch it a few times however appears wide open with enough water the skimmer will be full force. Full close all water flows from main drains , in between a mix - I read somewhere you want wanted from the main to go through the pump so that is is bringing water from the bottom of the pool though the filter , then back out the top for mixing. I am thinking since I leave my sweep 50% / main drain 50% I am already achieving that mix to some degree ?
Appreciate your time on this -
