Should a plumbing job ever be a do-it-yourself (DIY) endeavor? Maybe in some cases it can be okay. For example, maybe you have a superficial clog that’s close enough to the drain surface of your since that you can just eliminate it with a plunger and a little bit of “elbow grease.”
So no, we don’t always discourage DIY-jobs. But when it comes to your plumbing, it can be unsafe or further damaging to try to handle all problems on your own. You could even leave yourself more susceptible to problems in the future. There are 2 problems in particular we really encourage you to call in a pro for.
