I previously had DRF come out to diagnose a leaking hot water tank problem but because the part was not available thru manufacturer or local plumbing supply companies I had to get the part at Home Depot and recall DRF back out to install. My technician was Antuan and his helper Zach. Once again I got a great team of plumbers that were efficient, professional and helpful to get the job done in a quick fashion. I am so happy with their service I am glad to sing their praises and post this review so everyone reading this can feel assured that they are calling a honest company.
