    1. The WM15 has an adjustable (rotatable) inlet for appliance waste. It is also adjustable for length (drop). The other one is fixed horizontal.
    2. I would suggest you use the WM15.
    3. The connection from the trap to the waste pipe going through the wall may be an issue. The one you have at the moment could be push fit rather than compression. Can't really tell from the photograph. You might need some form of conversion to get the new trap to connect.
    4. Subject to 3, above, you shouldn't need anything else.
    5. Do you really need to replace it? Looks to me as if:
    5a. The joint to the waste fitting is leaking. Might need a new rubber washer, might just need tightening up.
    5b. The joint to the U bend is leaking. Looks as if the bottom white nut is on crooked / cross threaded. Might be possible to slacken all three nuts on main run of trap, remove bottom nut, refasten without cross threading then tighten all up.

    As above, try removing all parts then cleaning, check rubber cone washers for damage and are on the pipe the correct way round. Should be nut on pipe>plastic backing washer>rubber cone with small end facing away from the nut. Assemble all fittings loose to start then go back to tighten all nuts.

    Thanks for the detailed reply,

    Few more pics how the trap connects to the waste pipe:

    -----------

    I think you guys are right it probably could be repaired/adjusted, but it would take more time than I have, especially if the repair/clean doesn't work + it stinks to high heaven. Easier to replace.

    So the new trap will just screw on to the waste pipe?
