For this call, the homeowner reported inadequate hot water from a recently installed water heater. Upon arrival, I confirmed that the water heater was functioning correctly; however, the mixing valve was set improperly at 3.5 instead of the recommended 4.5, resulting in lower-than-desired water temperatures. I reviewed the mixing valve adjustment process with the homeowner for future fine-tuning of temperature preferences. The homeowner also noted a very slow leak at the male adapter connected to the filter housing. I shut off the water, relieved system pressure, and cut the pipe between the male adapter and the 90° fitting. I tightened the male adapter approximately one full rotation and installed a metal slip coupling to reconnect the piping. The system was restored, tested, and confirmed to be leak-free and operating properly at this time.
