One of the biggest mistakes you can make is going to a home center and renting your own drain-cleaning machine. It will not be long enough or powerful enough and you can cause more damage.
Commercial drain cleaner is another big no-no. It has harsh chemicals and can be very toxic as well as bad for your health and will eventually damage your pipes.
Do not try to install your own garbage disposal. It’s hard for a non-expert to align the pipes correctly, and if the drainage plug isn’t set right, garbage can back up into your dishwasher.
