My problem is that my AC unit is leaking badly from the piping attachment from the unit to the condensate pump. The past owner of the home apparently had someone to repair the attachment to the unit by placing duct tape around the pvc pipe to allow the condensation to flow to the pump. Looking at it, it appears like the pvc piping was broken off inside, so to do a temporary fix, a rubber tube was installed through the pvc pipe, which was covered with another tube and duct taped to the unit. It was then clued together. At the present time, the entire pvc tube has been detached due to the leak. How do I fix this?
