Hi, now that the furnace is on, I've noticed two very small water leaks from the PVC exhaust pipe junctions. Trane direct vent xv95. Maybe 1 tablespoon of water a day. On one I noticed a blob of silicone. There was lots of extra blue sealant on the lower edge also.

Is this anything to worry about? I do wanted the leaks stopped.

A tech will be out at some point for fall service, but is there an easy fix? Another blob of silicone...but the joint is a bit wet. Does it need to be dismantled and revealed?

Thanks.
Steve
