Best Backflow Preventer in Austin TX

I discovered a leak under my water heater at about 9am on a Sunday. I called Mr. Rooter and within an hour they were at my home. The two plumbers were extremely courteous, knowledge and totally transparent. Luckily it turned out it wasn't a major issue and they had the leak fixed and the water cleaned up within 30 minutes. I would not hesitate to use Mr. Rooter again. They are now my first choice for any plumbing issues.

Prompt service and scheduling for my annual back flow inspection. Would use again!

Beware. I would give a zero star negative if there is one. This guy is not showing up for scheduled. Response text after 9pm saying he was busy and will come do it tomorrow after 4pm. He called at 4:56 and I picked up but he already hang up. Called him right back about 30 times from 4:57pm-5:30pm and no response.
