Homeowner needs to replace a leaking tankless water heater recirculation pump and configure it to provide faster hot water without manufacturer-integrated control, resorting to a smart plug and Google Home app as a workaround.
The integrated thermocouple-based control never worked well, causing long hot water delays, and the plumber couldn't find a compatible replacement, leaving the homeowner to manual smart-plug cycling.
