Upon arrival customer stated he tried to install the tub drain and was not able to get it to sit properly. Gave customer estimate to install the tub drain. Customer approved estimate to install the tub drain. I screwed the adapter sleeve on first that I put putty on the tub drain and put the rubber gasket in between the drain and the tub and then tighten it up. Tested system and system is working properly with no leaks or issues.
