Why Pennsylvania Basements Need a Working Sump Pump
By the Duncan Family Plumbing team · October 20, 2026
Pennsylvania’s combination of a relatively high water table in many areas and heavy seasonal rainfall makes sump pumps a near-necessity for basements, especially in lower-lying properties near creeks and floodplains. A pump with a battery backup protects against the worst-case scenario: a power outage during a major storm.
Why Basements Flood Here
Groundwater naturally seeks the lowest point, and a basement floor is often below the surrounding water table, especially after heavy or sustained rain. A sump pump collects that water in a pit and pushes it away from the foundation before it can rise into your living space.
Testing Your Sump Pump
A pump that hasn’t run in months can fail silently. Pouring a bucket of water into the pit to trigger the float switch a couple times a year confirms it’s actually working — not just sitting there untested until the storm that matters most.
Why a Battery Backup Matters
Severe storms are exactly when power outages happen, which is also exactly when your sump pump works hardest. A battery backup system keeps the pump running even without grid power, which is often the difference between a dry basement and a flooded one.
Signs Your Sump Pump Needs Replacing
- It runs constantly, even without heavy rain
- It makes grinding or rattling noises
- It’s more than 7 to 10 years old
- The pit stays wet even when the pump seems to be running
