Sink Back Up Issue
We have a double sink in our bath and due to slow draining, I replaced the j trap this past Tuesday and on Wednesday the sinks were still draining slow and by Thursday, they started to back up. I read your column regularly and am ready to call a plumber or sprint off to the hardware store first thing Friday morning, depending on your answer.
No need to sprint off, enjoy our column, relax and finish your coffee. This is a simple fix. The drain needs to be “snaked” out. When j traps or p traps as they are commonly called are replaced, the replacement process can dislodge soap, toothpaste, hair, etc. which becomes lodged in the waste elbow and this creates a plug in the line. This is not a serious issue and will not take much time to correct.
