We were called for plumbing maintenance. Due to the water heater's age, installed in 2012, we did not flush it. The 50-gallon natural gas expansion tank was full of water, prompting an estimate for replacement. The client's home has a radon system and 2.5 bathrooms. A leak was confirmed from the first-floor half bath toilet, causing water to drip into the basement. An estimate was provided for a reset. Other toilets and laboratory pop-ups functioned well, with no water leaks observed. The standing showers and tub diverters operated correctly, with no dripping after use.
