  • Sometime the advice on here is meh imo.

    Silicons from real word experience is fine on stuff like this, and Id say personally a poster saying it should be just tighter than finger is nonsense needs to be tighter than that. It needs tightened but not horsed.

    Also slathering joints in paste after its fitted, if its gonna leak without paste it'll leak with paste and is just extra mess. Although I will say thats a thing that plumbers seem to be taught from working.

    The main issue with most of this waste stuff and lot of taps and that is that its cheap chinese crap.

    From my real world experience I'd say PTFE tape > silicone but I agree about slathering joints in anything.

    The main issue with this particular waste seems to be that it's not screwed on straight!

    @lemonade I would say @withered_preacher is right, get a different plumber. I could do a lot better than that myself and my plumbing experience is pretty limited...

  • But its all horses for courses, PTFE tape wouldnt work on what is being described with a waste, so I would always silicon it top and bottom as the washer never seal if you do it dry. You couldn't PTFE tape a flat washer.
