Flooding can happen anytime, anywhere. And damages are generally not included in your homeowners policy. But two devices can flood-proof your home: a backflow valve, and a sump pump.
Both control floodwaters by redirecting them.
A backflow valve directs overflow to an outside receptable – a sump pump directs overflow to a storm drain or well.
Both of these should be installed by a professional, and inspected by a service technician.
If you do it yourself, you could cause more damage, or void your warranty.
If flooding occurs, contact a professional as soon as possible, and only when safe to do so.
If left unattended, floodwaters can be harmful to your home.
