Noticed today that the pool is maybe 1/3 full. The water level is at the bottom step and about where it starts to slope in at the deep end. Am I correct to think that this points to it being the main drain or a liner issue?
I think I last checked it in December and it was about where I'd expect given the rainfall after I lowered the level for closing.
 
Probably a liner leak.

How old is the liner?
 
It's pretty old, I think, I planned to replace it soon as it's pulling away and kind of bleached. When we bought the house 3ish years ago, the pool inspector gave it 3-5 years. Is there some way to test that it's the liner without filling it and doing the leak testing?
 
Talk to companies that replace liners in your area and see about getting on their schedule.
