Pipe connected to furnace is dripping water.

We have the central air conditioner on, and one of the pipes leading out of the furnace and going through the ceiling to the roof vent is leaking water at the ceiling level and dripping on the basement floor. We do not have a condensate pipe leading to outside. We do have a hose coming from the furnace that drains in the floor drain and that is dripping water. Please help!! Let me know if I left out info. I have attached pictures of the pipe. It is leaking by the pink insulation.

Leak is from the pipe on right which goes to roof vent.

Pipe is the one on the right.

Welcome to the forums.

Those two large PVC pipes are only for the furnace.
One is fresh air in and the other is exhaust out.

It is expected to get water inside the pipes via condensation. The pipes are supposed to be pitched towards the furnace so that the water drains into the furnace and out the drain.

Since the furnace is currently not running.... water on the outside of that pipe would indicate a leaking roof boot on that pipe. If you have an attic you could confirm the leak thru the roof.
