Signs Your Sump Pump Is Failing
Don't wait for a flood to find out your sump pump isn't working. Watch for these warning signs:
- Pump runs constantly — even in dry weather — indicating a stuck float or failed check valve
- Pump won't turn on — motor failure, tripped GFCI outlet, or disconnected float switch
- Pump hums but doesn't pump — impeller is jammed or motor is seized
- Unusual vibrations or grinding sounds — debris in the impeller or worn bearings
- Water in the pit above normal levels — pump isn't keeping up or has failed
- Pump is more than 7–10 years old — sump pumps have a limited lifespan; proactive replacement prevents emergency flooding
Our Sump Pump Services in Knoxville
Sump Pump Repair
We diagnose and repair all sump pump issues — failed float switches, stuck impellers, tripped breakers, worn seals, and motor problems. If the pump can be repaired cost-effectively, we repair it.
Sump Pump Replacement
When repair isn't the right call — pump too old, motor seized, cast iron cracked — we replace it with a properly sized unit for your pit and basement volume. We carry submersible and pedestal pump options.
Battery Backup Sump Pump Installation
Power outages and heavy storms happen at the same time. A battery backup system keeps your basement protected even when the power goes out. We install backup pump systems that run independently of the primary pump and alert you when they activate.
Sump Pump Testing & Maintenance
Annual sump pump testing catches problems before they become emergencies. We test the float, check valve, discharge line, and power supply, and clean the pit of debris.
New Sump Pit & Pump Installation
If your home doesn't have a sump pump but has a moisture or flooding problem, we can assess whether a sump pit and pump system is the right solution.
Sump Pump Problems in Knoxville Homes
Knoxville's terrain — rolling hills, heavy clay soils, and heavy rainfall from Gulf moisture systems — makes basement and crawl space water intrusion a common issue. Neighborhoods with older homes (Bearden, West Hills, Fountain City, Powell) and newer developments with finished basements (Hardin Valley, Farragut, Karns) both see sump pump issues regularly.
Heavy rain events in Knox County can overwhelm undersized pumps or expose pumps that have been silently failing for months. We recommend testing your sump pump at the beginning of spring and fall each year.

Frequently Asked Questions — Sump Pump Repair Knoxville TN
How long do sump pumps last?
Most residential sump pumps last 7–10 years with normal use. Heavy-use pumps in wet areas may need replacement every 5–7 years. If your pump is approaching or past 10 years, proactive replacement is almost always cheaper than emergency flood cleanup.
My sump pump is running but my basement is still flooding — why?
The pump may be undersized for your pit volume, the discharge line may be blocked or frozen, or the check valve may be allowing water to flow back in after each pump cycle. We diagnose and fix the specific cause.
Do I need a permit for sump pump replacement in Knoxville?
Sump pump replacement typically does not require a permit in Knox County, but adding a new sump pit or changing the discharge line may. We advise you based on the specific work being done.
What's the difference between a submersible and a pedestal sump pump?
Submersible pumps sit inside the pit and are quieter and better suited to most residential applications. Pedestal pumps sit above the pit and last longer in theory, but are noisier and less common in newer installations. We recommend submersible for most Knoxville homes.
