Testimonials
"I am a contractor in Westchester County & I have used Joe & his company for 30 years now. I reccommend him to all my clients & have gotten nothing but great comments about his work."
"We needed backflow devices tested that are located in confined space water meter pits. We called J&J Backflow who gave us a quote. J&J supplied all the needed confined space equipment, air monitor, tripod and safety harness needed for confined space entry and surprisingly at a very reasonable price and much less than other testers."
"I needed to install a backflow device for my outdoor sprinkler system. I contacted J&J backflow spoke to Joseph he came the next day explain to me what I needed. One of his men I believe his name was Chris came install the backflow explain to me how everything worked after some Smalltalk he found out I was a firefighter and when I received my bill he actually gave me a first responder discount which I thought that was really nice and that many businesses do not offer that. I highly recommend if you need a company that performs these services to contact J&J backflow very fast clean it was a painless installation thank you guys for all your help ."
"Just had our backflow tested at The Edge on Hudson. J&J Backflow was very knowledgeable, on time and honest. He filed the report electronically on the spot and will notify us when the annual test is due. They beat all other testers prices. We will definitely use J&J Backflow every year and for all our plumbing needs.
They really are the best!"
