Editorial Review
Our Take on Reliant Plumbing
The review volume is what stands out. A 4.7 across 813 reviews is harder to achieve than a perfect five across thirty, and it points to a company doing consistent work at scale in San Antonio. The trade-off is what usually comes with size, so nail down the written scope and the after-hours rate before the truck rolls.
Best for: licensed 24-hour plumbing plus planned repipes and sewer replacement
What We Like
- 4.7 rating from 813 reviews on its Google Business Profile, read September 27, 2026
- Published hours show cover 24 hours a day, seven days a week
- Master plumber licence numbers RMP-42389 and M-42389 published on its own site
- Full range from drain clearing to trenchless sewer replacement and whole-house repipes
- Commercial and restaurant work listed, including grease traps and mechanical plumbing
- Trading since 2014 with branches across several Texas metros
Things to Consider
- The Whirlwind Drive address is listed on its own site as a distribution location, with a separate San Antonio service office on Fresno Street
- Awards, A+ BBB standing and satisfaction guarantees come from the company's own marketing and are not independently verified here
- Larger multi-branch operations usually price above independent one-van plumbers on small jobs
- No published price list, so ask for the after-hours rate and trip charge up front

About Reliant Plumbing
The range of work is the first thing worth understanding here. Reliant Plumbing lists everything from a leaking faucet through to trenchless sewer line replacement, and that spread is unusual for a company that also advertises same-day service. On the repair end you get drain clearing, toilet and fixture work, camera inspections and leak detection. On the project end there are whole-house repipes, sewer replacements, gas line installation, tankless and hybrid water heater conversions, pipe descaling, water softeners and whole-house filtration. Commercial work is listed separately, including grease trap replacement, restaurant drain maintenance and mechanical plumbing, which points to a crew used to health-inspection deadlines and kitchens that cannot close.
San Antonio shapes a lot of this. The water here is hard, and scale builds inside supply lines and water heater tanks faster than it does in softer-water cities, which is why descaling, softener installation and heater replacement come up so often in local plumbing work. Older housing in Alamo Heights, Monte Vista and the neighbourhoods inside Loop 410 still carries galvanised steel or early copper, and a repipe conversation there is a different job from a repipe in a 1990s Stone Oak subdivision. Post-tension slabs across the newer north and northwest suburbs mean slab leaks get found with acoustic and pressure testing rather than a jackhammer and hope, and the clay soils that move with every wet-dry cycle put steady strain on sewer laterals. That is the backdrop against which trenchless replacement earns its keep, since tunnelling under a driveway or a mature live oak is expensive and disruptive.
Day to day, the company runs on a booking-and-dispatch system with online scheduling, text updates and a customer portal, and it advertises free estimates with upfront pricing. Its own site says plumbers are licensed and background-checked, and licence numbers RMP-42389 and M-42389 appear in the site footer. Those are claims from the company, worth verifying against the Texas State Board of Plumbing Examiners register before work starts, which takes about a minute online. Reliant Plumbing also states it was voted a top three finalist for best plumbing company in Best of San Antonio 2026, and it links to a Better Business Bureau profile. Treat both as the company's own presentation rather than independent verification.
The Google Business Profile read on September 27, 2026 showed 4.7 from 813 reviews. That is a strong score on real volume. With a number that size, the useful exercise is not the average but the shape of the one and two-star reviews: on multi-branch plumbing companies the recurring themes tend to be quoted price versus final invoice, and technician consistency between crews. Read a dozen recent ones before you call.
Who it suits: homeowners and small commercial operators who want a licensed, insured company with a dispatcher answering at 2am and the capacity to send a second truck if the first diagnosis turns into a bigger job. Who it may not suit: anyone who specifically wants the same owner-operator on every visit, or who is price-shopping a simple cleared drain against the cheapest hourly rate in town. Larger companies carry overhead, and flat-rate pricing on a small job often lands above what an independent with a van would charge.
Before hiring, ask a few practical questions. Get the estimate in writing with the scope spelled out, and ask what happens if the camera inspection shows worse damage than expected. Ask who pulls the permit on a water heater swap, a repipe or a sewer replacement, because San Antonio requires permits and inspection on that class of work and the licensed contractor should be handling it. Ask what the after-hours rate is and whether the trip charge applies to the diagnostic or the repair. On heaters and repipes, ask which parts carry a manufacturer warranty, how long the labour warranty runs, and whether that labour warranty stays valid if you sell the house. On a slab leak, ask whether the plan is to break the slab and repair in place or reroute overhead through the attic, and what the cost and restoration difference is.
Compared with the alternatives in this market, the choice is roughly between small independent plumbers with sharper pricing but limited hours, and the larger franchised or multi-branch operations with dispatch centres and financing. This one sits on the larger side of that split while still being Texas-owned and run by its founder, which is a reasonable middle ground for most jobs.

Reliant Plumbing FAQs
Is Reliant Plumbing actually available 24 hours in San Antonio?
Published hours show open 24 hours every day of the week, and the company advertises 24 hour emergency plumbing for San Antonio specifically. As with any after-hours plumbing call, ask what the night or weekend rate is and whether a trip or diagnostic fee applies separately from the repair before you agree to a dispatch.
What is its Google rating?
Its Google Business Profile showed 4.7 from 813 reviews when read on September 27, 2026. That is a high score on substantial volume. Worth scanning the recent low-star reviews as well as the average, since on larger companies the recurring complaints usually cluster around pricing expectations or differences between crews.
Is it licensed?
The website publishes master plumber licence numbers RMP-42389 and M-42389, and states its plumbers are licensed, insured and background-checked. Those are the company's own claims. You can check a Texas responsible master plumber licence number free on the Texas State Board of Plumbing Examiners website, which is a sensible step before any permitted work.
Which address should I use in San Antonio?
The Google listing gives 4848 Whirlwind Dr, San Antonio, TX 78217, with the phone number (210) 900-4002. The company's own site describes that location as San Antonio distribution and lists a separate San Antonio office at 1119 Fresno St. For a service call the phone number matters more than the street, since the plumber comes to you.
Do they handle slab leaks?
Yes, slab leak detection and repair is listed among its services, along with camera inspections and general leak detection. Slab leaks are common in San Antonio because of post-tension slab construction and clay soils that shift seasonally. Ask whether the plan is to break and repair in place or reroute the line overhead, and what each option costs once floor restoration is counted.
Will they pull the permit for a water heater or repipe?
Ask directly and get the answer in writing. San Antonio requires permits and inspection for work of that class, and a licensed plumbing contractor would normally handle the application and the inspection appointment. Confirm it is included in the quoted price rather than billed on afterwards.
How long has Reliant Plumbing been in business?
Its own website says it has been trading since 2014, and it now lists branches in Austin, Lakeway, Bastrop, Georgetown, Waco, Temple, Dallas, Fort Worth and San Antonio. The founder, Max Hicks, is still named as owner on the site.
Is Reliant Plumbing licensed and insured?
We checked 0 of 1 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.
