Every install, complete.

Primary pump sized to your basin
Commercial-grade Pro Series pump, selected for your pit depth and duty cycle. Not the cheapest bucket pump from the big-box store.
Battery backup that actually works
Sealed AGM battery, load-tested at install, charger verified. When the power goes out during a storm — exactly when you need it — it takes over automatically.
New basin + brass check valve
We don't drop a new pump into an old basin with a brittle plastic check valve. Everything that touches the water gets replaced together, or it doesn't get done right.
Full system test and walk-through
Before we leave we cycle the system multiple times, verify the discharge line, hand you the paperwork, and show you exactly what you paid for.
Before. After.
Actual basements we've worked in. Muddy pits, corroded pumps, tangled float switches — and what they look like when we're done.


Mud-caked Zoeller, brittle discharge — replaced with a clean install and new check valve.


Flooded basin, corroded float — rebuilt with fresh pump, sealed lid, labeled runs.


Old pit, sediment up the housing — cleared, pump replaced, discharge straightened.


Neglected setup, failing check valve — full swap-out with labeled shutoff.


Water-stained basin, tethered float tangle — rebuilt with cleaner routing.


Cycling hard, losing prime — replaced pump, sealed basin, new discharge.


Aging install pushed past its lifespan — swapped clean, dialed in, tested.
How installation works.

45-minute assessment
Ryan looks at the pit, the pump, the discharge path, and the basement conditions. You get a written, fixed-price quote on the spot.

Same-week install
We arrive on time with everything needed. Drop cloths down, basement protected. Most installs finish the same day we start.

Test and hand-off
Multiple cycles tested, battery load-tested, discharge verified, walk-through done. You leave knowing exactly how it works.
Every basement is different.
Basin depth, discharge run, battery backup choice, exterior drainage conditions, whether you want a primary or a primary plus backup — these variables change the number by thousands.
So we do the 45 minutes of real work first. You get a written, fixed-price quote at the end of the visit. The number we quote is the number you pay. If we miss something, we eat it, not you.
Installation questions.
Most complete installations — primary pump, battery backup, new basin, discharge line, and testing — are done in a single day. We arrive in the morning and leave with a tested, running system by afternoon.
Pro Series combo systems: a primary pump sized for your basin and duty cycle, paired with a battery backup that keeps running when the power goes out. We don't stock five brands to upsell you — we install the one we'd put in our own basement.
Low. Most of the work happens in the basement around the existing basin. We lay drop cloths, clean up thoroughly, and don't cut into finished walls unless the discharge run requires it (we'll tell you upfront if it does).
3 years from the date of manufacture on all equipment (pump, battery backup, check valve) — standard manufacturer pass-through, we handle the paperwork. 1 year free labor on everything we install. Optional: upgrade labor to 3 years with our K-Guard annual maintenance or a one-time add-on at install.
We try. If you're in an active flooding situation during business hours, call us — we'll move heaven and earth to get someone out the same day. After hours, we respond first thing the following morning. The phone number is (614) 795-8090.
What Columbus homeowners say.
★★★★★
“Ryan took the time to explain exactly what was going on with our old sump pump and what we actually needed — no upsell, no pressure. The new system has been running perfectly through two major storms.”

“After getting wildly different quotes from three plumbers, K-Sump was the only one who showed me why my system was failing instead of just quoting a replacement. That honesty earned my business.”

★★★★★
“One year in, the labor warranty came through without a hassle. Sent a message, got a call back same day, fixed on the second visit. That's what honoring a warranty actually looks like.”
