Sump Pump Replacement & Repair in Grand Rapids, MI
Keep your basement dry with fast sump pump replacement, repair, and battery backup installation from NSP Plumbing.
Your First Line of Defense Against Basement Flooding
In West Michigan, a working sump pump is what stands between a heavy spring rain and a flooded basement. When a pump fails—or was never installed—groundwater has nowhere to go, and the damage can run into the thousands. NSP Plumbing replaces, repairs, and installs sump pumps and battery backup systems so your basement stays dry through every storm.
Whether your old pump finally gave out, runs non-stop, or you want a backup in place before the next downpour, our licensed plumbers will assess your setup and recommend the right fix—with flat-rate pricing and no surprises.

Signs Your Sump Pump Needs Attention
A sump pump usually gives warning signs before it fails. If you notice any of these, have it checked before the next storm:
Pump runs constantly or won't shut off
Pump cycles on and off rapidly
Strange grinding, rattling, or humming noises
Visible rust or it's more than 7–10 years old
Water in the pit isn't being pumped out
Standing water or dampness in the basement
Pump vibrates excessively when running
It didn't turn on during the last heavy rain
No battery backup on a finished basement
Pump already failed and water is rising? That’s an emergency—see our 24/7 emergency plumbing service or call (616) 207-9960 right away.

Sump Pump Service FAQs
Replacing a standard 1/3–1/2 HP primary sump pump typically runs $400–$900 installed, depending on the pump, pit access, and any piping or check-valve work needed. Battery backup systems add $600–$1,500. We give you a flat-rate written quote before any work begins.
Most sump pumps last 7–10 years. If yours is approaching that age, runs constantly, cycles on and off rapidly, or makes unusual noises, it's smart to replace it before the next heavy rain rather than risk a failure during a storm.
If the pump is under a few years old and the issue is a stuck switch or clogged intake, a repair makes sense. If it's near the end of its lifespan, has burned out, or has already failed once, replacement is the safer, more cost-effective choice.
If your basement is finished or you've ever had water intrusion, yes. Sump pumps run on household power, so a storm-related power outage—exactly when you need the pump most—can leave your basement unprotected. A battery backup keeps it running when the power is out.
Constant running usually points to a stuck float switch, a failed check valve letting water flow back into the pit, an undersized pump, or a high water table. We diagnose the cause and fix it before the pump burns out.
Yes. If your basement takes on water and has no sump system, we can install a new sump pit, pump, check valve, and discharge line to keep the space dry. We'll assess your basement and recommend the right setup.
Yes. A failed sump pump during heavy rain is an emergency—we offer 24/7 response to get a working pump back in your pit fast and limit water damage.
Most homes are well served by a 1/3 HP or 1/2 HP pump, but the right size depends on your water table, pit size, and how high the water has to be pumped. We size the pump to your home so it isn't overworked or oversized.
