I just replaced the toilet, sink, and faucet in my bathroom and I now smell sewage from the sink. Everything is basically the same, although I had to get a drainpipe extender - still have p-trap though. Ideas?
Added pic but let me know if the angle is what you need and thank you!
Follow-up: since the sink and faucet I installed in the other bathroom don’t have this issue, ordered those exact products and going to reinstall to see if this remedies issue. Did not have to do the drainpipe extender on the other one and it was more exactly centered. Thanks for the thoughts and will update after I do that.
