Inground skimmer has no suction.
I have cleared the pipe from skimmer to pump.
I do not see any water (level) leaking from pool.
Pump works great on main drain.
Suspect small air leak, but can not find.
Any suggestions

Use a drain cleaner that hooks up on a hose. Stick it down inside the skimmer hole where it would suck from. ( if the bottom of the skimmer has 2 holes, its usually the one farthest from the pool) then turn on your hose and then check the pipe especially around where the pipe is threaded into the pump for leaks.
