The past few nights when I have checks in my equipment pad I have noticed dampness on the concrete under one of the PVC pipes where it comes out of the inline tab feeder. I can feel under the pipe at the connection and it is wet. Suspecting a small leak, This morning when the pump kicked on I was there and watching this area. Within a few minutes a small drop of water formed and dropped to the concrete pad. It is more like a seep and a drop only forms every few minutes, but it is a drop of water, so it is very slowly seeping or leaking water at this connection. It is a PVC glued connection. What would be the easiest way to reseal this connection can I use some epoxy to seal it? Or will I need to cut it out and re do this potion of the plumbing? Even though I do not use it, I do want to keep the tab feeder for when we go out of town. The problem is the PB did not use unions and I think he just glued the PVC into the inlet and outlet of the feeder.
