Hello - your kit does not specify that it includes a key to tighten the waste pipe. Please confirm how this is done? Thanks
Hello,
The key works like a wrench, you just need to assemble all waste trap parts together and then push the key from above and turn it around few times.
It should tighten the screw and connection between the waste to the drain.
I will be happy to assist if you have any questions.
Kind regards
