Came to customers home to inspect the main waterline for iron piping. Dug by the meter and found that the customer had a PVC main waterline. Customer inquired about a filter for his home and we informed him we do provide and install whole home filters. He was happy to hear and was eager to have one installed. We cut out and replaced the PRV with a new PRV. Installed a new Halo 5 unit in the basement of the customers home. Went through the regen/flush cycles in the new filter. Flushed out all fixtures in the home.
