Best Backflow Preventer Repair in Phoenix AZ

It was time for my annual residential fire sprinkler inspection. I had used their services before to replace a stuck sprinkler control valve so I decided to give them a call to see how long it would take them to come out and do an inspection. WOW! Even though it was a Friday late afternoon, they had a technician team in the area and sent him straight away. The team came out, checked everything out, showed me around the fire sprinkler since I wasn't too familiar with it, and then wrapped things up. Great service. And great pricing too! Thank you.

WSI is fantastic!  Being an older widowed female, I am always concerned that I will be taken advantage of. WSI refurbished my existing sprinkler system. I was prepared to have to start all over again.

They were very reasonably priced and saved me a lot of money. The customer service was awesome and the owner listened to my concerns and made sure the job got done right. Use WSI for your sprinkler needs

Dave is easy to work with, honest, and very helpful. The next time I need any backflow preventer valve work on the west or north side, I'll be calling him again.
