After arriving to the home, the homeowner made me aware of two issues. One was a potential gas leak on a Navien Tankless we installed less than a year ago, and the other was a leaking tub faucet. We began at the tankless unit, located in the garage. He had another plumbing company come out and perform a safety check on the house, and during this time they detected a gas leak at the tankless unit. The homeowner explained that they had a electronic device that detects gas and said that they noticed it alert them by the tankless and outdoor hvac unit. I began by using a non corrosive leak detection solution, and applied it on the exposed fittings by the tankless, no leaks were detected with the solution. The odor of natural gas wasn’t present either. The leaking Roman tub faucet is located in the downstairs master bedroom, and the valve was leaking water around the hot side handle. I attempted to remove both handles to see whether or not it would be possible to replace the inner component
