15 below now after first thaw leak

[Makdaddy]

So I went out to pump water off the cover
I have a dribble from the return

Now I left my pool full and used one of those expandable tubes for the skimmer
But I just used a plug for the return
Could it have frozen and cracked?
Plus now I need to figure out a way to keep the water away from the base of the pool its dripping real steady.
My cover goes over the sides and covers the return not sure If I can get a hose on it or not

Did you drain/ blow out the lines before closing?

Its just the 3 inch connector that the hose goes to to fill the pool from the pump.
I have a screw in plug on the inside of the pool.
It is leaking in that pipe ,so I assume the screw in plug (seal) broke or cracked.
Im looking at some Conduit plugs , they are like putty, that might seal it till spring.
