I was forced to seek service from this company as it was the only one licensed to service my water heater under warranty. They sent a conning plumber, whom said that he needed new parts and will have to wait until they arrive in order for the heater to work, and charged me for his visit. He never showed up again nor did he answer the calls, after about 3 months, I heared loud water sounds and the walls were oozing water in the house, and I called in another plumber as emergency and he stated that all seemed to work just fine with the heater, but the water filter clogs up every now and then and would have to be cleaned, that is all, and he mentioned that last time it was cleaned they did not put the pipes accurately that caused the big leak.
