How Long Do Sump Pumps Last? Useful Tips To Ensure Longevity
The sump pump is a crucial component of the plumbing system, preventing basement flooding, water damage, and other issues by pumping water from the basement or sump pit into the drainage system.
How devastating would it be to see a flooded basement despite having a seemingly resilient plumbing system? The sump pump is a crucial component of the plumbing system, preventing basement flooding, water damage, and other issues by pumping water from the basement or sump pit into the drainage system. It's essential to consider sump pump replacement periodically.
The average lifespan of sump pumps is about ten years. However, if the sump pump operates frequently, bi-weekly inspections are required due to the gradual wear and tear that can lead to pump failure.
When Should One Consider Replacing the Sump Pump?
Submersible sump pumps are typically placed in the sump pit, the basement's lowest point. They divert water away from the foundation and into the sewer system, thereby preventing basement flooding and protecting the foundation.
Submersible pumps make less noise because they are submerged in water, which muffles the sound of the motor. This placement also facilitates easier movement around the basement.
Although submersible pumps are less likely to get clogged compared to pedestal pumps, they have a shorter lifespan. Here are common issues that might necessitate a pump replacement.
Noisy Sump Pump
Noise from the pump may indicate worn or broken parts. Excessive noise can be due to worn bearings. Rattling or grinding noises might suggest a stuck or broken impeller.
Excessive Shaking When Running
If hard debris damages the impellers of an improperly installed pump, it may cause an imbalance. This misalignment puts undue stress on the shaft, leading to noisy wobbling and potential future issues. Impellers usually cannot be repaired effectively, necessitating their replacement.
Infrequent Use
Like car batteries, sump pumps degrade over time if not used regularly. Testing the pump during heavy rain ensures optimal performance. Persistent operation due to switch issues is common, often involving the float, an essential component of the electric switch. Misalignment within the basin, malfunctioning floats, or power issues can cause erratic pump behavior.
Long-term Usage
A pump that fails to move the desired amount of water or reach the required distance needs reassessment. Several factors must be considered to determine the appropriate pump size.
Frequent Power Outages
Most sump pumps are directly wired to the house's electrical system. Power surges can damage the pump. If the sump takes too long to clear, the pump might lack the necessary horsepower for the volume of water or the complexity of the pipe network.
Rusty Pipe
Rust in the sump pump indicates a need for replacement. Rust buildup, often caused by iron bacteria, impedes water flow, overstraining the pump.
Tips on Maintaining Sump Pumps
Maintenance varies by model; consult the owner's manual for specific guidelines. Generally, if the washing machine drains into the sump pump, the screen or inlet should be cleaned regularly. Unplug the pump for cleaning, but reconnect afterward.
For pumps without laundry discharge, clean the screen or inlet every three to four months.
Annually remove and thoroughly clean the pump.
Factors Affecting the Longevity of a Sump Pump
Installing a Sump Pump of the Wrong Size
Pumps must be appropriately sized. A small pump might suffice for minor water ingress but could fail under more substantial demands, potentially causing overflow and damage. Conversely, an oversized pump might shorten its lifespan due to excessive work. A waterproofing expert can provide the best advice on the suitable pump size and handle installation.
Improper Installation
A poorly installed sump pump can fail prematurely. Errors during installation, such as incorrect motor setup, misaligned float switches, or improper connections, can cause significant issues.
Lack of Proper Maintenance
Neglecting maintenance shortens a pump's lifespan. Regular servicing ensures the longevity of the waterproofing system and optimal pump performance. Failure to monitor and maintain the pump can lead to unnoticed malfunctions, especially problematic during dry seasons when issues may worsen unnoticed until heavy rains occur.
