Completed service call for follow-up estimate on potential water heater replacement and recirculation system installation. Inspected current 12-year-old water heater, which is functioning but approaching end of typical service life. Provided updated quotes for 75-gallon tank with mixing valve and recirculation pump options to address customer's long hot water delay issues (60ft distance between water heater and kitchen). Customer will review options and contact us when ready to proceed.
