The sink drain is clogged. What to do?
Hello. You probably just have a clogged sewer. Have you tried cleaning it mechanically, for example, with a plunger? If that doesn't work then it's best to call a plumber. Perhaps you just need a more powerful cleaning of drains and everything will fall into place again. I have a link to the website of a plumbing repair toronto company . I advise you to leave a request and call the master. They will assess the condition of your pipelines and do what needs to be done.
