Overflow doesn't have the holes for return nozzles (Help)

3rd hole is a trickle line, just a little water in it. It acts to balance the overflow and keep it in line.

If I were you I would consider going with PVC for the drains. Your flow wont be nearly as good with flexible tubing. Plus you need to use valves, not sure how that would work with tubing.

For tubing I can use these..... pipe is too mainstream for me yet lol

You are welcome to do whatever makes you happy, but I suspect you are going to have a very hard time getting that to work properly.

Take it from a guy who has done it - use a gate valve. If you have to have tubing, buy a Gate valve that's one nominal size too large and glue some female pipe thread bushings in the valve and use hose barb fittings with teflon tape.

Read my post carefully...I basically tell you exact what each drain whole in the overflow should be used for. If you read the link on beananimal that should help with the details.

I know what I will do...
I will do tubing so something similar to this when I drill my 2 return holes

That looks pretty good. Only thing I would change, the returns look a little small, I'd size them a little larger. Otherwise seems like a decent route to go.

Yeah I agree with u, his returns are small

Looks good if you're going to braided tube route. I see the returns are also connected to check valves. How big of return hoses are you going with? Primary drain has gate valve which will help you fine tune.

I am going to use the 3-4" loc line returns
I see this package for a 3-4" loc line return kit, I'm not sure what drill size I need for a 3-4" loc line but is this package right?
Please look
