It sure looked easy in the directions, but proved more than this homeowner could handle; replacing shower kit, which involved enlarging the access panel on the wall, cutting copper tubing, replacing the lines & the new valve. It did take some time to replace the valve (2.5 hours), but the tech finished the job. However, it did require a call-back visit to switch the hot/cold water cartridge. Overall, pleased with the finished result.
