Hi guys. I noticed in my sump room that my sewer main end cap, just before it leaves house to sewer, the end cap has some old cement looking yellowish stuff on it but I see a small gap on the last most threads. Nothing is leaking but wanted to make sure the cement stuff isn't breaking down already (house built in 2001). I really do not want to mess with this sewer main cap for obvious reasons but I don't want it to eventually start dripping either. Is it safe to just put a bead of 100% silicon caulk over the small gap in thread and the gap where the adapter meets the pipe and be done with it??? Here's a pic
