Community guidelines:
If you have a plumbing question please include a picture in your post.
If you have a question such as "does this look correct?" please include the code your area adheres to. If you're not sure please include state/province/country you're in. Codes can vary state to state and what's wrong in one area may be perfectly acceptable in another.
Just as codes vary, prices do too. That's why we won't discuss any pricing because there's so many factors that can't or shouldn't be conveyed to strangers over the internet.

Darn, thanks for the info... huge noob here. To clarify, after it leaked the first time, I was careful not to go too tight for that reason, but it still leaked again after that so I only did it harder just now.
I suppose there could have been a crack in it already. More importantly, is this something an amateur could investigate and fix? ๐ Thank you!!
It's plastic on plastic. Despite being PVC, it has a limit. Next time, a bit of nylon tape or pipe sealing tape would be the right move.
Good luck.
Gotcha! Sorry, just to be sure, you mean tape on the thread of that hexagon piece to give some space between the plastic pieces?
Not to give space, but to make the threads seal up.
The tape helps create a seal. You wrap the tape around the screw's threads, then you twist the nut onto the screw.
Yes. Nylon tape on the threads of the cap. The "hexagon piece" is a plug and the hex is just there to give you something to tighten it with. Sometimes you see them with a recessed hex instead of an exposed one. Same function. The tape creates a seal the same way a gasket does.
Fantastic, thank you!
