A sump pump is only as good as its discharge. The field standard: discharge water drains away from the foundation — never into a neighboring low spot or back against the wall. Sizing follows the water table and basin volume, not a rule of thumb, and a battery backup is the difference between a dry crawl space and a flooded one during the storms Knoxville gets.
The basin should be sealed and vented per code, with the discharge line pitched to drain fully (a frozen or sagging line is the #1 silent failure in Knoxville winters).
Inspect Before You Replace
Before replacing a pump, a pro verifies the failure wasn't upstream: check the check valve, the float switch travel, and the discharge line. If the pump runs constantly, the real problem is often groundwater volume — which is a drainage question, not a pump question.
