FAQ

Your water provider (city or utility) requires backflow preventers to be tested on a set schedule, and the letter means yours is due. Follow the deadline on the letter and send us a photo of it when you book.

Backflow preventers are tested when they’re installed. Updated state and local rules have increased how often they must be retested to keep public drinking water safe.

They stop water from your sprinkler system, pool or other equipment from flowing back into the public water lines. That keeps fertilizer, chemicals and bacteria out of everyone’s drinking water.

It uses spring-loaded check valves that let water flow only one direction. If pressure drops and water tries to reverse, the valves close and block it.

For most homes with sprinklers, it’s a few feet from the water meter, often in an underground box near the curb. Some are above ground near the house.

Yes. Once payment is received, we file your results electronically through your city’s system (BSI Online, VEPO, or Austin Water’s WEIRS, which becomes Klir on November 17, 2026) and send you a copy for your records. Want to look it up yourself? Check your backflow test status.

Most cities file your report in an online portal. Which one depends on your water provider:

• BSI Online is used by Round Rock, Leander, Cedar Park, Pflugerville, and Travis County WCID No. 17. You’ll need the Customer Confirmation Number (CCN) from your notice letter.
• Some cities, such as Georgetown, use VEPO (Envirotrax) — check your letter or water provider if you’re not sure. Georgetown customers can often search by property address on the public lookup.
• Austin Water uses its own system: WEIRS, moving to Klir on Tuesday, November 17, 2026.

Not sure which system your city uses? Check your notice letter or call us at 512-835-2211.

Heads up: As of Tuesday, November 17, 2026, Austin Water is retiring WEIRS (the old backflow / Water Protection filing system) and moving test tracking to Klir. Austin Water emailed registered testers about this change; the new Klir login link for the public may arrive with their follow-up notices.

Until cutover, some Austin customers can still use the WEIRS customer login if they already have an ID. After November 17, use whatever Austin Water publishes for Klir, or start from Austin Water’s Cross-Connection / Water Protection page.

We’ll show you what failed and explain your repair options and cost before doing any work. After the repair, the device is retested and the passing result is filed. Most cities allow 30 days to repair and retest.
