Customer had a widespread faucet in unit bathroom that was dripping after manufacturer sent new cartridge for replacement. Checked house pressure to rule out underlying high pressure as a possible cause. House pressure is in a safe range. Noted to customer that heater was manufactured in 2015 and was showing signs of rust on the body. Offered customer to fix faucet leak as a courtesy if done in conjunction with a new heater. Customer accepted. Replaced the heater with a new drip pan, shutoff, and strapped thermal expansion tank. Tested all work to ensure proper function and no leaks, none were found.
