Editorial Review
Our Take on Plumbing One, LLC
A 4.9 average across 308 Google reviews is the kind of number that usually reflects steady, unremarkable competence rather than marketing spend, and that is a compliment in this trade. The weekday-only hours are a real constraint worth planning around, but for scheduled work, backflow testing and sump pump systems, the case here is easy to make. The clear statements on card fees, financing and discounts also spare you a conversation most contractors would rather avoid.

iAbout service coverage
Coverage is as the business describes it, cross-checked against where its recent documented work is. A company will often travel beyond the areas listed here for a large job and decline a small one at the same distance, so confirm your address before scheduling.
About Plumbing One, LLC
Canal Winchester sits on the southeast edge of the Columbus metro, close enough to Pickerington, Groveport and Reynoldsburg to reach most of Franklin and Fairfield counties without a long drive. That geography shapes the service list. Plumbing One LLC lists coverage across Delaware, Franklin, Fairfield, Licking, Madison, Pickaway and Union counties, which is a wide spread taking in both older Columbus neighbourhoods and the newer subdivisions pushing out toward Etna and Sunbury.
What they take on runs from the small and urgent to the substantial. Clogged drains, leaking faucets, running toilets and failed shut-off valves make up the bread and butter. Beyond that sits water heater repair and replacement, sump pump and battery backup work, drain and sewer cleaning, gas line service, water line repair, appliance hook-ups and repiping or relocating pipe during a kitchen or bathroom remodel. The owner's background, as described on the company site, leans heavily toward sump pumps and backup systems, which is worth knowing in a region where basements are standard and spring groundwater is a recurring nuisance. The linked Facebook and YouTube accounts belong to Aqua One Waterproofing, suggesting a related basement water management side to the operation.
Backflow certification is the detail that separates this firm from a lot of small residential shops. Columbus and many surrounding water systems require annual backflow prevention assembly testing on irrigation systems, fire lines and certain commercial connections, and the tester has to be certified with the relevant authority. The company states it holds State of Ohio and City of Columbus credentials with a licensed plumber on staff and backflow certification. If you own a restaurant, a small industrial building or a home with a lawn irrigation system tied into city water, that is a practical reason to have the number.
The review record is the strongest piece of third-party evidence available. On September 4, 2026, the Google Business Profile stood at 4.9 stars from 308 reviews. Volume at that level takes years to accumulate, and the average has held up, which generally points to consistent scheduling and pricing that matches the quote. The company claims more than 25 years of service and BBB accreditation on its own site, along with no hidden fees and a satisfaction guarantee. Those are the company's own words rather than independently confirmed facts, and worth testing against your own quote.
Hours are the main limit. Published times are 7:30 AM to 4 PM Monday through Friday, with Saturday and Sunday shown as closed. Plenty of Central Ohio plumbing companies market around-the-clock emergency response and charge accordingly. This one does not appear to, at least not in what it publishes. For a water heater swap, a sewer camera inspection, a remodel rough-in or an annual backflow test, weekday scheduling is fine and often cheaper. For a supply line that lets go at 11 PM in February, you may need a second number on the fridge. Ask directly whether after-hours calls are answered and what the call-out charge looks like if they are.
Payment terms are unusually clear for a trade website. Cash, cheque and card are accepted, with a 3.5% service fee noted on card payments, and financing is advertised at rates starting as low as 0% with prequalification that does not affect your credit score. A 5% discount is offered to military personnel and seniors on any job. Estimates are advertised as free. Before booking, it is reasonable to ask whether the estimate is a firm price or a range, how permits are handled for gas line and water service work in your jurisdiction, and what warranty covers both parts and labour.
Who it suits: homeowners in the southeast quadrant of the metro and the surrounding counties who want a smaller, owner-involved firm rather than a large branded fleet, plus commercial clients needing backflow testing and estimating handled through a dedicated email. Home inspectors and realtors are explicitly welcomed, which fits the pace of Columbus transactions where a repair list has to be cleared before closing. Who it suits less: anyone whose problem cannot wait until Monday morning. Weighed against the bigger Columbus operations, Plumbing One LLC trades round-the-clock availability for a longer track record with the same two owners and pricing that is spelled out up front.

Plumbing One, LLC FAQs
What areas does Plumbing One cover?
Central Ohio, specifically Delaware, Franklin, Fairfield, Licking, Madison, Pickaway and Union counties, according to the company's own service area listing. The office is at 7393 Long Rd in Canal Winchester, which puts Pickerington, Groveport, Reynoldsburg and southeast Columbus within an easy drive. Outlying parts of Union or Madison county are a longer trip, so it is worth confirming scheduling when you call.
Do they handle emergency call-outs at night or on weekends?
The published hours are Monday to Friday, 7:30 AM to 4 PM, with Saturday and Sunday shown as closed, so weekend and overnight cover is not advertised. That does not always mean nobody answers, and it is worth asking directly about after-hours availability and any premium charge. If you need guaranteed 24-hour response, have a second Columbus plumber on hand.
How is Plumbing One LLC rated?
Its Google Business Profile showed 4.9 stars from 308 reviews when read on September 4, 2026. That combination of a high average and a large review count is a reasonable signal of consistency, though reviews should be read alongside your own quote and a clear scope of work.
Can they do backflow testing for a commercial property or irrigation system?
Yes, the company states it has a certified backflow tester and holds State of Ohio and City of Columbus credentials. Annual backflow prevention assembly testing is required by many Central Ohio water authorities on irrigation lines, fire suppression connections and certain commercial services. Ask which jurisdiction's paperwork they file for and whether the test report is submitted on your behalf.
What payment methods and discounts are available?
Cash, cheques and credit cards are accepted, with the company noting a 3.5% service fee on card payments. Financing is advertised with rates as low as 0% and prequalification that the company says will not affect your credit score. A 5% discount is offered to military personnel and seniors on any job. Estimates are advertised as free.
Do they work with realtors and home inspectors?
Yes. The company says it is happy to work with home inspectors and realtors across Central Ohio and surrounding areas, which usually means handling repair lists generated by an inspection before closing. For those jobs, ask for an itemised written scope so it can be attached to the transaction paperwork.
Do they take on both residential and commercial jobs?
Both. There is a separate estimating email for commercial enquiries, which suggests commercial bidding is handled apart from day-to-day service calls. Residential work covers the usual range from drain clearing and water heaters through to sump pumps, gas lines and remodel pipe work.
Is Plumbing One, LLC licensed and insured?
We checked 0 of 4 credentials against the issuing authority. Verified items carry the date we checked; reported items are what the business told us and we could not independently confirm.
What areas does Plumbing One, LLC serve?
Columbus, Canal Winchester, Blacklick. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does Plumbing One, LLC offer emergency service?
Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.
What warranty do they offer?
Warranty terms are not on file. Ask for them in writing before work starts.
How was this profile built?
Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.
Can a business pay to improve its profile?
A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
