What this page is
Austin Plumbing Pros is a referral service that connects Austin homeowners with independent, licensed Texas plumbers. We don’t perform the work ourselves — but the guidance we publish needs to be accurate, because people read it during emergencies. This page explains how we vet the plumbers we dispatch, the hierarchy of sources behind our guidance, how pages are reviewed and updated, and our full reference list.
How we vet the plumbers we dispatch
Before a plumber receives a dispatched call, and on an ongoing basis, we check:
1 · Active Texas (TSBPE) license
Plumbing in Texas is licensed by the Texas State Board of Plumbing Examiners (TSBPE). We confirm the plumber holds an active Master or Journeyman license in good standing — and you can verify any license yourself on the TSBPE License Verification page. We encourage you to.
2 · Their own insurance & bond
Each dispatched plumber carries their own liability insurance and bond. We are a dispatch service, not the contractor — the licensed plumber who does the work holds the license, the insurance, and the responsibility for it.
3 · Permits pulled the right way
In Austin, a plumbing permit must be pulled by a Responsible Master Plumber licensed by the state and registered with the City. We expect dispatched plumbers to pull permits where the City of Austin building code requires them and to work to the adopted Uniform Plumbing Code.
4 · Local & responsive
We match by ZIP and build era so the plumber knows local conditions — Austin’s slab-on-grade construction, expansive Houston Black clay soils, and the moderately hard municipal water that affects fixtures and water heaters.
Our source hierarchy
When a claim could affect a homeowner’s decision, we source it — in this order of authority:
1. Codes & licensing authorities
The Uniform Plumbing Code (UPC), published by IAPMO and adopted by the City of Austin with local amendments (Land Development Code Ch. 25-12, Art. 6), together with the Texas State Board of Plumbing Examiners, are our first reference for how plumbing work is licensed, permitted, and performed in Austin.
2. Government & utility sources
The U.S. EPA WaterSense program for water-efficiency specifications (WaterSense toilets use ≤1.28 gallons per flush, lavatory faucets ≤1.5 gpm, and showerheads ≤2.0 gpm), and Austin Water for local water-quality and hardness context — Austin’s surface water from the Highland Lakes is moderately hard, which is why scale affects local fixtures and water heaters.
3. Manufacturer specifications
For product-specific facts — water-heater capacities, anode-rod and thermal-expansion-tank requirements, valve and fixture flow rates — we defer to the manufacturer’s published specifications and installation instructions rather than generalizing.
How pages are reviewed and updated
Pages are researched and written by the Austin Plumbing Pros team, reviewed for local accuracy against the sources above, and stamped with a “last reviewed” date that we only change when a page is actually updated. We review freeze- and winter-related content before winter — the February 2021 Winter Storm Uri freeze burst pipes across Central Texas, so this is not theoretical here — and we review hard-water, water-heater, and cost content at least annually, or sooner whenever a code, specification, or local condition changes.
What we don’t do
We don’t publish fabricated reviews, star ratings, or fake testimonials. We don’t claim to be a licensed plumbing contractor, and we don’t display a license number or a street address we don’t have. We don’t invent prices — costs on this site are typical ranges for guidance, never quotes. And we never cite a source we haven’t verified actually says what we’ve written; every reference below resolves to a real, current source.
