Looked around Home Depot brand pure aqua softener unit, found manual online and ran units through backwash cycle Customer reported the units had not undergone a cleaning cycle in a few weeks, and was also notching smells within the hot and cold waterlines, found the water level in the brine tank was a little high and possibly caused by the incomplete backwash cycles After completing cycles checked water levels again which were good Ran water at kitchen faucet to ensure no further smells within the waterlines Spoke with customer about the units that we install and offer, and how maintenance on a waterrite unit is earlier done because of part availability, and the support team available through waterrite Emailed estimate for the installation of a new iron out softener unit
