The customer had a piece of half inch copper stubbed out with a saddle valve that was no longer working for the.Refrigerator waterline. Customer agreed to have a refrigerator shutoff box installed behind it. Performed work by turning off the water to the house and draining as much of the water as possible.And then cutting a roughly one foot by one foot hole in the sheetrock, to access the copper behind it cut out the stub out and installed a refrigerator shutoff box. Cleaned up after myself and then turned the water back on to the house and slowly primed everything out of the lines. As well, I ran several cups of water through the refrigerator afterwards.Testing for leaks and getting the debris and carbon out. No further issues at this time.Thank you for choosing and trusting t e with your plumbing needs
