There are two piping systems in your house; one delivers the water to your faucets (the water line), and the other takes away the water that you’ve used (the drain system).
Noisy leaking pipes, a clogged toilet, water backing up in your sink, tub, or shower, are symptoms of a bigger problem.
Think about it. Something caused that stoppage and unless the root of the problem is found and solved, you could be facing expensive water damage to floors, ceilings, walls, or worse. If a sewer pipe bursts or if sewage backs up into your home, your home will be exposed to harmful bacteria and toxic mold.
So while it may be tempting to have a go at the problem yourself, messing around with it can result in serious damage to your home.
