Marketing InformationLead-free construction is suitable for all no lead potable water installations, in full compliance of the national lead-free plumbing law. Press-to-connect end connections are designed for installation onto ASTM B88 types K, L and M hard drawn copper tubing. Coiled (annealed) soft copper tubing is not recommended, but can be used if ends are made round. Eliminating the need for soldering, press type connections reduce labor and material costs and eliminate the fire hazard associated with the soldering process. End connections are compatible with commercially available VUS profile jaws. Waste drain allows line to be drained for maintenance or to prevent freeze-up, an ideal isolation/winterization valve for exterior sillcock installations.
