Day 3 trying to find a leak.

Day 1- Bucket test revealed a loss of 3/4" w/pump running
Day 2- Shut off main drain loss of 1/4" w/pump running

Thoughts?

The main drain is a suction line. If it were cracked would it not be pulling in dirty water? I am having issues with the pump not getting to full prime.

How many skimmers do you have? A main drain at the bottom of the pool?

Post pics of your equipment pad and the suction side of the pump.

Look around your skimmers for any cracks or leaks around the skimmer mouth.
I squirted dye slowly and didn't find any. I do know there is a crack but I've been patching it the past couple of years with epoxy.

This morning I turned off the pump and shut off the main drain to see if there is any difference.

Are you having issues with full prime even with the skimmer shut off? How is the suction piping and valving? Can you isolate each skimmer and drain from eachother?

Interestingly, yes. I have shut off both the skimmers and main drain independently and still having issues with prime. Do you see my issues as related?

Tomorrow morning I will post pictures of my plumbing. Thanks again

EDIT: Never mind. Re-read your post again and what I said would not appear to apply.

As an aside, I see all of your above ground couplings are none-pressure-rated DWV. If the underground coupling are also DWV, then your problem could originate here.

If you have plugs try plugging each skimmer independently one then the other and running just the skimmer line. See if u can isolate the line. Your leak is on suction side. My issue is if either line is chosen and you cant get full prime your drawing air in somewhere. The pool leak may not be related. A picture of the pool helps too
