I installed a new sink this weekend, and as a result I had to redo the drain pipes.
At the joint to a 90 degree elbow and the Y there is a small leak. The pipes are 2" diameter, and I fear that I did not allow them to set enough or I did not put enough glue on them. I typical work with PVC involves irrigation systems that are a much smaller diameter.
Given that I only have access from the outside is there a way to fix the small leak?
