"They were able to assess the job with a couple of photos to recognize the old power-vent heater I had and what a replacement would cost. We discussed options, and they could upgrade me to a tankless heater for a relatively small increase. Was in and out fairly quickly and we were very satisfied with the new tankless."

"Talked to Scott I explained what needed to be done. Sent a couple pictures of the problem and he gave me a price. We are very pleased with the outcome off the work. The workers were on time and did a professional job installing and piping the spigots. There was no mess when they left. They were the cheapest of the 4 plumbers I talked too. Some didn't even call me back. They even left a gift which is super helpful and appreciated!!! Thanks for a job well done."

"My tenant's water heater stopped working. I called this company and they came out that same afternoon and installed a new one. The whole process went well and my tenant had hot water right away."

"Carlos is excellent. He is very responsive, professional & reasonably priced. He & Eli installed a new water heater very quickly for us after our old one started leaking. I highly recommend CAB Backflow and would absolutely use them again for other plumbing jobs."
