I've just replaced a kitchen sink but it seems to be draining very slow now. Also, after reading some threads I think I might need to re-do the offset trap. The old setup was a two bowl sink plus disposal. My questions are;
1 - Could this setup be the reason for a slow drain? All parts are new or have been cleaned, and it seemed to be fine before. This is also a new strainer basket, but with the strainer removed it is still pretty slow to drain.
2 - Should I re-do the offset, so that it is tail-with-dishwasher/p-trap/horizontal/long bend/wye?
Thanks for reading!
