Anyone ever try the product Leak-B-Gone
http://www.pvcleakrepair.com/ to stop a slow drip in a PVC line? I have a sink basin with a PVC drain that has a slow drip at a 45 elbow. Replacing the PVC is not an option without removing the sink and that is not an option due to the placement of the sink.
Or what are your tricks of the trade to stop a leak without wholesale pipe replacement? I've reapplied primer and glue with some success but this product has me intrigued.
