Solar wiring through vent, how to seal hole in vent line
I had to bring the wire for my rooftop solar panels down through the kitchen sink vent pipe. I drilled a 3/4 in hole to fish wire through; how have others sealed this hole?? Thanks, Doug

Go get a plastic coupler same size as vent pipe. Cut in half lengthwise, notch the cup to slide over wire glue on and seal gaps with 3M 5200. Tie wire works good to hold in place while adhesive sets.
