Repair or Replace?
If the pump is 8+ years old, replacement is usually the better investment. If the pump is relatively new and the issue is a float switch or check valve, repair may be sufficient. A battery backup is strongly recommended for all sump pump installations in Knoxville.
Factors to consider
- —Age of the pump (5–7 year typical lifespan for pedestal, 8–12 for submersible)
- —Whether the pump runs but doesn't remove water (motor vs. impeller issue)
- —Whether the pump runs constantly (float switch or check valve issue)
- —Whether a battery backup is needed
Before Calling a Plumber…
A few safe, simple checks may save you a service call:
- ✓Pour a bucket of water into the pit to test whether the pump activates
- ✓Check whether the pump is making unusual noises or running constantly
- ✓Check the discharge pipe outside for proper flow
Many Knoxville homes with basements or crawlspaces rely on sump pumps, especially in areas with high water tables or heavy spring rains. A battery backup is strongly recommended — power outages during storms are exactly when sump pumps are needed most.
