Roof is probably 8 years old John.

Feed line is copper and runs outside across the roof, so that's not it.

There are no legs as such, but only the connection to the roof jack.

I struggled with this last summer too, and attempted to remove old seal around the flashing and reseal it, and I think that might have been the cause of rain leaks. The re-flashing I had done this summer seems to have fixed the rain leak issue, but not the cooler leak. I am going to attempt relining the pan with vinyl and if that doesn't work, its replacing the swamp cooler.
