Specifications include, but are not limited to: Water Conditioning Equipment Replacement: • Remove existing twin water conditioning equipment and dispose of off-site in a legal manner. (see: selective demolition spec) • Install new twin alternating water-conditioning system capable of maintaining three or less grains of hardness. Water conditioning equipment shall have boiler drains located at the bottom of resin tanks for winterization. See equipment specifications based on H151-090 Twin Alternating Water Conditioning System or its equivalent. (see: twin water conditioning spec) • Install any/all needed piping, fittings, full port isolation ball valves, unions, and bypass valves. Install piping so that it slightly slopes back to the equipment or install a boiler drain at the lowest point of the piping for winterization. (see attached: typical twin tank installation detail) • Pipe the backwash discharge to a sanitary sewer drain. • Installation to comply with all applicable building and plumbing codes. • Put all new equipment into service, including any programming needed and test the new equipment. • Take a final conditioned water sample, analyze it, and provide the results to the owner for verification of hardness. • Provide training on the system to the DNR site staff. Insulate Domestic Water Piping: • Insulate all domestic water piping in such a way that does not interfere with the function of manual valves, flush valves, unions, fixtures, or equipment. (see: flexible elastomeric cellular insulation spec)
