Forum Title: Slight leak on compression ferrule
Hi there, installing a PTrap on a new bath tub and going from galvanized to standard 1.5" PTrap. The guy at Ace sold me a brass adapter that screws onto a threaded section and then accepts the PTrap pipe using a brass compression ferrule. When I leak test I get a drop or two of water coming from the spot with the arrow. Do I need to just tighten it more or? It's pretty tight already I think...

I read various you should's and you shouldn'ts about doping the ferrule. Not just tighter? And why would that not be your choice? What would? I just bought a PTrap... It's pretty much like what I replaced too.

Put some pipe dope on the ferrule. Also that wouldn't be my choice for a tub trap.

FYI - tried to edit my last post, didn't work... Anyway, did a bit more reading - you would use PVC? The overflow that came with the tub is 1.5 brass... much like the trap in the pic so it seemed natural. I thought it odd to go from the brass to pvc then to galv. Also - this trap is accessible.
