kitchen waste trap

[wanttolearn]

Hi I have attached a pic above as a friend of mine her waste is leaking. As I am only learning the trade I was thinking if I put a 1 and half bowl waste p shape trap in this should solve the problem. I know I may have to re drill out for the waste outlet as it's fairly high up in the cupboard.

As you looking at the pic the strainer on the left looks like it 32mm waste pipe I will have to increase it to 40mm and the one on the right is the problem one it is leaking from just below the plastic nut but is full of silicone so didn't really want to undo it as there is nothing open till tomorrow nearby me.

So would that be an appropriate way of doing it thanks

Both outlets should be 40 mm but your logic is sound

Undo the nut and check/replace the flat washer
Also check the bottom of the thread of the waste fitting itself, could be cracked or damaged and the trap set up could be OK
