Best Backflow Preventer Certification in Phoenix AZ

DO NOT USE THIS COMPANY.  They over-charge for labor on a simple job.  They will never give you the price up-front and they will  make a mountain out of a mole-hill.  They truly are intent on charging whatever they want after the fact.     FIND ANOTHER COMPANY!     These other YELP reviews are phony.

Initially we got a bid to fix water pressure and a valve system on our front yard with another company; the bid was upwards of $6K, which is insane!  I found Williams Sprinkler on Yelp and noticed they were close to me and had a good reputation.  Curtis was responsive on phone calls, showed up on time, and communication throughtout was tremendous.  Dealing with contractors, communication can be the biggest headache, but not with Williams Sprinklers; they kept me informed every step of the project.  Nate joined Curtis on a complex valve changed and delivered!  We now have grass growing back in spots that were dead due to bad water pressure and sprinkler heads.

I am happy with my new sprinkler system and recommend Williams Sprinkler & Irrigation on a fantastic install!

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.
