Unless damage is due to a city main blockage or pipe breakdown, homeowners bear the responsibility of costs related to pipe repair or home damage. It’s a good idea to check your insurance plan to ensure coverage before problems occur since many policies do not cover flood damage to your home or business. #### Best Practices for Preventing Sewer Backup in Your Home - **Avoid pouring materials down your drains** that can lead to clogging. This includes grease, butter, and bacon grease as well as foods like coffee grounds, eggshells, and raw flour - **Avoid flushing** paper towels, diapers, **wipes**, or other paper products - **Switch to plastic pipes** to prevent tree or shrub roots from growing into your sewer line - **[Inspect your main drain](https://www.plomberie5etoiles.com/en/video-camera-inspection)** for any plumbing connections - **Regularly clear** debris from gutters and downspouts and make sure they are not connected to your sanitary sewer line If your **drain is backing up** and causing damages, please contact us right away at **[514-447-3700](tel:514-447-3700)**. Start by speaking to our qualified technician over the phone, we can help guide you in the process to reduce water damages before dispatching a plumber. Afterward, our professional plumbers will visit your home or business unblock your drain. Whether its **sewer backup caused by tree roots** entering a broken drain or **clogged drain by foreign materials** such as paper or grease, we at **Plomberie 5 Étoiles** can help you.
