I installed a threaded bulkhead in my new sump. I placed a threaded ball valve at the exit with a "nipple" screwed into each end, and then screwed one end of the ball valve into the threaded bulkhead. When I tested it dry, I had a very small leak (1 drop every 5 minutes coming from the connection of the nipple and ball valve...not the bulkhead). I put teflon tape on both nipple threads and tightened every thing up. It's been two hours now without leaking a single drop. Sound good to go?, or should I also place a bead of Silicone around the bulkhead flange where it meets the interior wall of the sump?
