Best Backflow Preventer Replacement in Austin TX

Diamond irrigation did a fantastic job on our irrigation system. We installed a pool and the pool company completely tore up the backyard irrigation. George and his crew did a new install and connected lines to the front yard to get everything working again. Very professional, great communication along the way and his team showed up on time and worked into the late hours to finish up laying sod. Even when there were a few issues along the way, Diamond irrigation took accountability and rectified them in a timely manner.
Excellent customer service and respectable company that gets the job done right.

I needed help with connecting NG line to outdoor kitchen. Chad was great to work with. He took the time fully understand the job and provided a very reasonable quote.
He also tried his best and worked me into his busy schedule to get the job done.
Overall I highly recommend reaching out to him if you feel he could help you out.

Before you use this company, I strongly urge you to do your research!!!! I'll share my experience here and you can learn from my sister's misfortune of dealing with this company. I recently visited my sister because I was getting married. Since we had a house full, I asked to use her shower. Not even midway through the shower, the water pressure deteriorated from a flow to a poor stream and ended at barely a trickle! I was furious and so was she as this was a matter she has been dealing with for over a week. She called Mike, who claimed he had properly repaired the water issue but I bare witness, he hadn't repaired anything!!! He doesn't carry warranty for he work on purpose so you, the consumer, has no choice but to call on his mediocre services again. I dare say his services cause more damages than you had upon his arrival!! Again I urge you to do your own research as this company is lackluster and waste of your time, energy and money!

This guy was great! My spigot popped off about midnight last night. I requested emergency quotes. A&D backflow  responded within 20 minutes. He even requested an immediate phone consult to determine if he would be able to fix it right then! Unfortunately it couldn't be as the wall needed to be cut into. Anyway, he showed up bright and early. He had everything fixed and back to normal in no time. He answered all the questions I had and explained various reasons why it might have happened and how to avoid it happening again. He was very professional and friendly. I will most definitely be using this company again and HIGHLY RECOMMEND!!

I can't praise these guys enough. I have been using them for about 11 years and they always do great work with my yard maintenance, landscaping, and any sprinkler repairs that are needed. They have also helped with some close friends sprinkler install, and they have been happy with that work as well. Very fair prices, and always gets the job done right!

Very impressed at the knowledge and corrections made to my irrigation system. Thank you so much

Our water heater went out and we needed a replacement fast. Gabe was the first to reach out and offered to replace our unit the same day. His quote was very affordable compared with others that we received. His work is high quality and he made adjustments so if there is a need in the future repairs will be easier to perform. I highly recommend Gabe, and we now have a new plumber!

This company stood me up for my appointment not once but TWICE and never called. The first time I called them after they were 45 minutes late and they told me they would call the guy that comes out for the estimates. 20 minutes go by and still no call back so i call again and they tell me they cant get ahold of him. If everyone was running late why not call me to tell me that? Then we rescheduled for 2 days later and I am assured they would be on time. After an hour of waiting and several attempts of getting in contact with them (and no answer) I left again. Got a call 3 HOURS later saying he was running behind again. Why not just pick up the darn phone and call so I'm not wasting my time? EXTREMELY unprofessional company. Do not recommend them at all.
