We installed a new Rheem 50 gallon gas water heater with Grundfos hot water recirculation pump and comfort valve. The install included a reroute of the gas line for better access, new safety drain pan, audible leak alarm, thermal expansion tank strapped and secured, temperature and pressure relief line with a drip elbow, vent pipe brought up to current local code, hot and cold ball valve shut offs, and a new supply stop for HVAC humidification water supply. The system was pressurized, air was removed from the lines and everything was tested for proper operation with no issues.
