There are several common reasons why sump pumps stop working.
- Switch failure
- Dirty intake screens
- Damaged impellors
- Blocked discharge pipes
Although homeowners can troubleshoot minor problems, tampering with a sump pump’s motor or other moving parts could void its manufacturer’s warranty. Scheduling professional sump pump services will allow for fast and accurate diagnosis and long-lasting solutions without compromising this or any other protections or equipment guarantees.
Like all other home appliances, sump pumps require annual maintenance. If your sump pump hasn’t received professional maintenance in a while, this is the most likely cause of your current issues. Corroded batteries and a buildup of bacteria can leave sump pumps riddled with rust and cause noisy, erratic operation.
Rattling and grinding sounds often indicate problems with sump pump fans and may be due to built-up or trapped debris. Surprisingly, not using your sump pump often enough can cause problems as well. Infrequent use gives many minor and developing issues the chance to spiral out of control.
Sometimes, age and general wear break down key components even when these units are diligently maintained. These include float switches, check valves, and impeller blades. Unfortunately, while it’s possible to repair float switches and check valves, damaged impeller blades indicate the need for total sump pump replacement. Replacement is often also necessary when improper sizing and faulty sump pump installation cause recurring problems.
