I called for service for a stopped garbage disposal. I was happy the kind woman who took my call. Very profesional. Dan Chavez was here within an hour of my call. Dan was friendly, helpful and kept me informed of what was needed and how it was going to be done. He cleaned my sink and the area where he worked. I felt comfortable and happy with his great service and look forward to using this company and Dan when future needs arise. Thank you so much. Grateful he is a Diamond Bar resident also.

These guys are awsome! I called them at 5am, when I notice that my water heater was leaking water all over the garage. The girl who answered the phone was very courteous and assured me that they would be there immediately. She explained to me how to turn off the water so that no further flooding would ruin the things in my garage. They showed up within an hour and fixed the problem that day. Thank you so much, A&A Plumbing!

Zach came out to our house at a minutes notice to replace a pressure regulator and a shut off valve that had been leaking for sometime. He did a great job, he made the outside faucet look better then it has since we've lived here. He was efficient, clean and reasonable. I would use Green Hippo plumbing for all our plumbing services. I highly recommend Green Hippo plumbing!!!
