Couple of leaks

[Vic8710]

Fitted a new waste pipe and bottle trap for the new sink but unfortunately ended with a few leaks and wondering if someone could suggest solutions on how to rectify them.

One between the basin waste and the bottle trap, i guess i am needing a washer here but not sure which one to go for.

Second leak is a the pipe and the corner joint i have clearly not tested it enough to make sure there's no leak there. Is there a way to fix the leak without removing the pipe?

Thanks in advance for all your help.

The “corner” joint is solvent welded, which usually require remaking. As for your bottle trap, yes you need a washer.

Just for your info, make sure you coat both the inside of the fitting and the external pipe surface before inserting the pipe. Also, don’t use too little solvent weld.

Either of the above can cause leaks like you have.

Edit: as you’ve got no more pipe coming out of the wall to easily remake it.
Cut the elbow off at the horizontal socket (side furthest from the wall).
Then make a couple of cuts a long the length of the remaining socket (parallel with the pipe) but just through the socket, not the pipe.
Then use a flat screw driver to pry off the socket.
Clean the pipe and you should be able to reuse it.
