Show up prepared
Gather the property context before the visit and bring the right tools for the likely scope.
Locally owned in Austin, Texas
Skilled field work. Direct communication. No runaround.
H2O & Backflow Tests was built to make water-system service easier for homeowners, property managers, HOAs, and commercial facilities.
Why the company exists
Property service works better when someone sees the whole system.
Plumbing, backflow, irrigation, remodeling, hydrants, and underground fire lines are often treated as unrelated trades. On the property, they are connected.
H2O brings those connections into the diagnosis and planning process. That means fewer handoffs, clearer recommendations, and one accountable team helping move the work forward.
What guides the work
Simple standards that show up on every visit.
The goal is not to sound complicated. It is to make complicated property systems easier to understand and manage.
Explain the result
Tell the customer what was found, what matters now, and what can wait.
Close the loop
Handle testing, repairs, retesting, documentation, and follow-up without leaving loose ends.
Credentials
Licensed where the work demands it.
H2O is insured and TCEQ licensed for backflow testing. Texas Master Plumber RMP #43657 is on staff, with private hydrant and underground fire-line registration support for qualifying commercial scopes.
Public credentials and standards
Trust should be verifiable.
Customers should not have to rely on a logo or a claim to understand who is responsible for licensed work.
Texas plumbing licenses and consumer guidance are available through the Texas State Board of Plumbing Examiners. State cross-connection rules and public-water guidance are available through the Texas Commission on Environmental Quality.
H2O identifies the responsible license, defines the work boundary, and keeps testing, repair, retesting, documentation, and project follow-through connected whenever the scope crosses disciplines.
Who we work with
Built for owners and operators who need a clear answer.
H2O supports homeowners, HOAs, property managers, restaurants, apartment communities, offices, schools, retailers, and commercial facilities across Central Texas. The service plan changes with the property, but direct communication and accountable follow-through do not.
Residential
Repairs, annual testing, installations, fixture planning, and remodel support for individual properties.
Managed properties
Reliable coordination for HOAs, apartments, multi-family communities, and property-management teams.
Commercial
Documentation-aware service for restaurants, offices, retail centers, schools, and private fire-water systems.
