I had a leaking water heater that was still under warranty. KJT Plumbing was the original installer of the water heater and could not schedule service for a month! They told me any plumber could handle the warranty work and referred me to Ferrin Ryco. The dispatcher at F R even acknowledged the warranty situation. F R showed up and said no, they couldn't do anything regarding replacement under warranty. They thought it was a defective pressure relief valve, replaced it, and it didn't fix the problem. Then said I could remove the water heater, take it to Rheem dealer to get replacement, and they could come back and install OR they could put in a new unit. Seriously? Charged me $150 and didn't fix the problem. Very disappointed in KJT referring me to such a plumber that knows nothing about providing good customer service. I ended up calling Rheem which provided me a list of plumbers and found one that honored the warranty and took care of everything, no hassles whatsoever.
