914 Sump Pumps & Backup in Westchester County, NY
A sump pump is the last line of defense for most Westchester basements with interior drainage. Waterproofing companies and plumbers install new pits and pumps, replace failed pumps, add battery or water-powered backups, and reroute discharge lines so water does not cycle back toward the foundation.
What to know in Westchester
Storms that bring heavy rain often bring power outages, which is when pumps are needed most and most likely to fail. A battery backup or water-powered backup, plus a discharge line that sends water well away from the house, are worth discussing for any home that relies on a pump. Plumbing work in Westchester can require a county trades license in addition to a home improvement license; see our licensing guide.

Plumbing licenses
Westchester County issues plumbing licenses separately from home improvement licenses, through its trade licenses search. We searched that database on Oct 27, 2026. Where a company or its plumber appears there, the license number is shown on its profile. A name that is not found means only that we found no record under that name, so ask any company that installs or connects a sump pump who does the plumbing and confirm that license number with the county. Work outside the building, such as a yard drain, is often not plumbing work, and rules vary by town.

Frequently asked questions
How long does a sump pump last?
It depends on the pump and how often it runs. Pumps in wet basements that cycle frequently wear out sooner. Test yours every few months by pouring water into the pit.
Do I need a backup pump?
If your basement takes water whenever the pump stops, a backup is cheap insurance against an outage or a stuck float switch.
Why does my sump pump run constantly?
See our guide to a sump pump running constantly for the usual causes, from a high water table to a stuck switch or a missing check valve.
