I have a strong smell coming from kitchen sick that just won't go
away.........it smells quite strong.

I have removed the cap that screws on at the bottom and nothing there
and I have checked and cleaned trap, and yes there was scum there. I
cleaned the best I could , but still strong smell.

How do I fix this? where is it coming from?




I have checked and cleaned trap

When you say "checked", does that mean the trap was full of water when you
pulled it or removed cleanout nut?
