Not all plumbing repairs in the home necessarily need the attention of a professional, as some clogs, leaking faucets, and other such issues can be fixed by most homeowners, and with nothing more than standard, everyday tools. However, while some repairs can be DIY jobs, some are better left to a plumber, either to ensure the work is done right or because the repair itself may be more complicated than you realize. Note when you may need a plumber for a supposed DIY plumbing fix in your home, and why it's best to leave the work in their capable hands rather than address this problem yourself.
If you notice that there are mismatched pipes in the area of a water leak, meaning pipes of two different metals or a PVC pipe attached to a metal pipe, this could be the reason for the leak. Mismatched pipes can very easily corrode when exposed to water and to the materials that run through the pipes, including bleach and drain cleaners.
However, you want to have a plumber note which type of material is best for needed new pipes and connectors. Those new pipes should match all the pipes in the walls, so a plumber should inspect the entire plumbing system in the home and then decide on replacement materials.
Using an auger
An auger is a good choice for clearing clogged drains and toilets, but they're actually more difficult to use than you might expect. Many homeowners make the mistake of buying one that is too long, or that is powered by electricity, so that it's cumbersome and difficult to control. They may also inadvertently push the clogged material even deeper into the pipes rather than dislodging it, making the clog worse. If you've tried a plunger for a clog and think an auger is the next option, call a plumber to manage this tool for you and clear that stubborn clog.
Replacing a sink
When you put a new sink in the kitchen or bathroom, it's not as easy as you might assume, even if you buy a new one of the same size and design as the current one. You need to ensure the plumbing pipes are properly attached and at the right angle so that clogs don't form, and also ensure that the connectors are tightened around the new pipes without getting stripped. Your new sink also needs to be caulked or sealed properly, to avoid water leaks around the edge. Because this job might be more complicated than you realize, leave it to a professional.
