Millions of dollars are spent every year repairing damage to basements caused by sewer and drain backups. There are some ways these problems can be avoided, instead of having to repair the mess from a sewer or drain backup.
Make sure your drainage systems are working properly. The downspouts from your gutters should extend beyond the foundation of your home so that water is not left to trickle down basement walls. Along those same lines, your yard should gradually slope away from the foundation, so surface water drains directly to the street. Keep drain lines clear, especially if your gutters connect to storm sewers.
There are several types of anti-backflow devices that can help reduce the chance of basement flooding. Check-valve devices allow water and sewage to flow away from the drain, preventing backup into the drain. Gate-valve devices close and shut off the flow of water and sewage, preventing backup. Anti-backflow devices are either manually or automatically operated.
Sump pumps are another option to consider. Single and dual-level sump pump systems are available, and a battery or generator can be used to power the pump in case of a power failure. Sump pump systems should be checked monthly. Check local building codes or consult your plumber to ensure your sump pump is connected properly. Sump pumps should not be connected to your home’s waste plumbing system.
Despite your best efforts, sometimes water will still get in your basement. Keep storage items off the floor and keep furniture on casters or shims, away from floor drains. If your basement is finished, ensure that you consult plumbing and building professionals to design a drainage system that will prevent damage to your finished space.
Despite the amount of damage backups can cause, many homeowners’ policies do not include coverage for sewer and drain losses. Check with your agent to determine if an additional endorsement can protect you from this costly problem.
