If you're having trouble with your toilet or drains, you may be able to resolve the problem on your own.
If your toilet becomes clogged, use a plunger to push the blockage through the pipes. If you need to flush the toilet, only do so once. Multiple flushes could cause the toilet to overflow.
If your sink or bathtub isn't draining properly, there is likely a clog in the line. You can also use a plunger to move a clog out by pushing it over the drainage hole and pumping vigorously.
Do not use chemicals like Draino in your pipes, as these may cause permanent damage to the system.
