Why H2O & Backflow Tests

Most properties juggle three vendors — a plumber, a backflow tester, and a fire line contractor. That means three invoices, three schedules, and a lot of follow-up.

H2O & Backflow Tests handles all three under one roof. Licensed Master Plumber, TCEQ-certified backflow testing, and private fire hydrant service from a single local team. We test, repair, and file results directly with your city, so compliance and repair stay simple from start to finish.

Q How do I schedule service?

Scheduling is easy — call (512) 755-7318, email h2obackflowtests@gmail.com, or use the Schedule Service page. Having your name, phone, email, property address, and a quick note about the work helps us get you on the calendar faster.

Q Why choose H2O & Backflow Tests?

Customers choose H2O & Backflow Tests because one local team handles plumbing, backflow, and fire line service under a Master Plumber and TCEQ-licensed backflow tester. Owner Caleb Hopkins is a lifelong Burnet County resident, and the company is built on fast scheduling, clean compliance reporting, and straightforward work that keeps property owners from juggling multiple vendors.

Q What plumbing services do you offer?

H2O & Backflow Tests provides full plumbing service for residential and commercial properties — including leak diagnosis, fixture installation and replacement, pipe repairs, system troubleshooting, and general plumbing work designed to keep your system operating the way it should.

Q Are you a licensed plumber in Texas?

Yes. H2O & Backflow Tests operates under Texas Master Plumber license RMP #43657, regulated by the Texas State Board of Plumbing Examiners. That means every plumbing job is performed under the supervision of a licensed Master Plumber — exactly what HOAs, property managers, and commercial clients should require.

Q How much is a plumbing service call?

The standard plumbing service call is $175. For multi-unit properties, larger commercial work, or project quotes, call (512) 755-7318 to discuss the scope.

Q Can you help with hard-to-diagnose leaks?

Yes. Whether it's an unexplained leak, a recurring plumbing issue, low pressure, fixture trouble, or a system that just isn't behaving, we can inspect the issue, diagnose the cause, and recommend the right repair or next step.

Q Do you install fixtures and handle pipe repairs?

Yes to both. Fixture work covers sinks, faucets, toilets, shutoff valves, and other common components. Pipe repair is one of the most common reasons customers call — whether it's a visible leak, worn components, or a repair needed to restore proper system performance.

Q Do you handle remodels and new construction?

Yes. H2O & Backflow Tests handles plumbing tied to remodels, upgrades, and new construction. If you have a project coming up, call (512) 755-7318 to discuss scope and scheduling.

Q What is backflow testing and why is it required?

Backflow testing verifies that a backflow-prevention assembly is operating correctly and protecting the public water supply from contamination. Annual testing is commonly required by cities and water authorities to make sure the device still passes under pressure and remains compliant.

Q Who typically needs annual backflow testing?

Backflow assemblies are commonly required for irrigation systems, commercial buildings, apartment complexes, restaurants, medical facilities, car washes, schools, and some residential properties. If your city or water provider has notified you that testing is due, the assembly likely requires annual certification.

Q Are your technicians TCEQ-licensed to test in Texas?

Yes. All backflow testing is performed by TCEQ-licensed professionals — exactly what cities and water authorities require for compliant reporting and customer peace of mind.

Q Are you registered with BSI and VEPO?

Yes. H2O & Backflow Tests is registered with both BSI and VEPO — the two main reporting platforms Central Texas water authorities use to receive test results. That means we file your paperwork directly with your city so you don't have to.

Q How much does a backflow test cost?

The standard backflow prevention assembly test is $115. For multi-device commercial properties or HOA scheduling, call (512) 755-7318 to confirm details and request a quote.

Q Do you also install and repair backflow assemblies?

Yes. In addition to annual testing, we handle backflow installations and backflow repairs. If your device fails a test or needs to be replaced, one team can handle the whole process start to finish.

Q What is private fire hydrant testing?

Private fire hydrant testing is the inspection and testing of privately owned hydrants on commercial, multi-family, industrial, HOA, and private development properties. The goal is to confirm each hydrant is accessible, operating correctly, and properly documented for compliance and recordkeeping.

Q What's the difference between a public and private hydrant?

A private fire hydrant sits on private property rather than as part of the public municipal system. Apartment complexes, warehouses, office parks, retail centers, private campuses, and HOAs often have private hydrants that are the responsibility of the property owner or manager — not the city.

Q How much does a fire hydrant test cost?

The standard private fire hydrant test is $125 — no hidden fees, no surprise taxes. For properties with multiple hydrants, call (512) 755-7318 to discuss a quote.

Q What happens during a private fire hydrant test?

A typical visit includes a visual inspection, operational checks, valve exercising, condition review, and flow-related testing where applicable. We document everything for compliance recordkeeping and explain any findings or recommended next steps.

Q Do you also work on underground fire lines?

Yes. In addition to hydrant testing, H2O & Backflow Tests handles underground fire line testing and repair and fire hydrant repair. If your property has issues with the hydrant, related line, or overall private fire water infrastructure, one call covers the full scope.

Q Can you help with Austin Water's private hydrant forms?

Yes. We're familiar with Austin's private fire hydrant program and help clients with the testing and documentation side of compliance. You can find Austin Water's official Private Fire Hydrant Inspection and Test Form directly through their resources.

Caleb and his team at H2O and Backflow Tests are the absolute BEST in the business. They have helped us for the past two years filing our backflow tests with the City of Austin. They are also our go-to for post freeze repairs. They are quick to respond, come out assess and repair, and retest when needed. If you have a pool, H2O and Backflow Test is a must have on speed dial.
