Basement Flood Risk Check for Union, NJ
Living with a basement in Union? Score the precautions that keep storm water and sewage out of it.
Why Union basements need a water plan
Union Township sits between the Rahway River and the Elizabeth River, and much of the township was built out with basement homes in the decades after World War II. When the remnants of Hurricane Ida crossed New Jersey in September 2021, basements across Union County filled from groundwater, overflowing sewers and surface runoff in a single night.
- Test the sump pump and add a backup before storm season.
- Ask a plumber about a backwater valve on the sewer lateral.
- Keep downspouts and grading moving water away from the foundation.

Basement Flood Risk Check for Union, NJ: common questions
Why do so many Union basements take on water?
Most Union homes were built with full basements, and many rely on a sump pump to keep groundwater out. Heavy rain, snowmelt and a power outage during a storm can overwhelm the pump, and an aging sewer lateral can back up through the floor drain.
What does a backwater valve do?
A backwater valve lets sewage leave the house but closes when the public sewer surcharges, so storm-swollen sewers cannot push wastewater up through basement drains.
Is basement flooding covered by homeowners insurance?
It depends on the source. Sudden pipe bursts are often covered, sewer and sump backup usually needs a specific endorsement, and outside flood water falls under a separate flood policy. Coverage depends on your policy, so it is worth checking with your own insurer.
How often should a sump pump be tested?
At least once a year and before storm season: pour water into the pit, confirm the float lifts and the pump empties the pit, and check that the discharge pipe is clear.
