Many homeowners use a sump pump for waterproofing their basement when it is located near the water table level. The pump is a versatile device, with several models available to suit various needs based on the location of the basement, the amount of water drainage required, and the power needed to operate it at optimal levels. While sump pumps can be very effective in keeping a basement dry, homeowners need to be aware of a few hazards that can lead to flooding, mold, and rot.

　　One fairly common problem with sump pumps is illegal dumping. Your pump may be draining into a sanitary sewer, which makes you liable for fines if you fail to correct it. Many older homes have pumps that are still connected in this way. When too many pumps are connected to the system, or there have been heavy rains or flooding causing excessive drainage from homes, the local sewage treatment system can be inundated by this water, causing far-reaching problems. One way to check to see if your sump pump is draining into the sanitary sewer is if it drains into a deep sink. If you suspect you're dumping into the sewer system, it is important to reroute your waterproofing system so that it connects to a storm drain. While receiving a fine or warning from the local council is rare, if you do plan on selling the home in the future it is better to follow the code.
