NAPCO Royal Pipe and Fittings announced the new NAPSYS-HR PVC DWV (drain-waste-vent) product system is now available to customers. The newly designed system meets all low smoke and flame requirements of the Canadian Building Code and is available in a size range of 1.5-inch to 10-inch diameter. The launch marks NAPCO Royal Pipe & Fittings reentry into the significant high rise segment of the Canadian building market. The low rise product-system currently in-market will be rebranded under a new name — NAPSYS-LR PVC DWV to complete NAPCO’s DWV offering in Canada.
