GSHA Services, LTD upgraded the domestic hot water system for a homeowner in Lake Forest, IL over two visits. First, our plumber installed a new thermal expansion tank on the water heater cold-water supply to absorb pressure spikes and protect the tank, fixtures, and relief valve, which is required by code on homes with a backflow preventer or pressure-reducing valve. Next, we installed a Grundfos 15PBG-6B hot water recirculating pump with a programmable timer at the water heater so hot water is available almost instantly at every faucet and shower, cutting the wasted water that used to run down the drain. Both installations were leak-tested and the timer was programmed around the family's schedule.
