Your drains are one of the most important parts of your home. They are responsible for taking all the sewage from the toilets, sinks, and bathtubs from your home, and taking them outside to the sewer line or septic tank. If your drains are clogged, or if there is a problem with waste not making it out of the house, it can cause very serious health problems. Water backs up through your sink and bathtubs, and toilets don't flush properly. It can also cause damage to your floors and basement. If your drains are clogged, or have a blockage, you should contact a professional plumber right away. You never know what damage could be caused by the sewage backing up through the drains.
