Common Sump Pump Failures

Basement Detective performed a survey involving 5 major waterproofing companies to find out the top 5 reasons sump pumps fail.
The results were no surprise to any of those experienced in the field of foundation waterproofing.
1. Pump was unplugged. This almost always happens intentionally. Like when a homeowner needs to use an outlet or an electrician is performing something and forgets to replug the pump.
2. No check valve installed. Many non professionals will gladly install a pump without a check valve.
3. Check valve installed backwards.
4. Cheap pumps that just burn out.
5. Mud clogged system burns pump out. Poor system installs that lead to failure.
