KITEC PLUMBING FIXTURES -IPEX
IPEX's composite pipe, which is known as Kitec®, consists of flexible aluminum pipe sandwiched between an inner and outer layer of plastic pipe (PEX Pipe®). Kitec® generally comes in two colors: blue (for cold water use) and orange (for hot water use).
These connectors were recalled by the manufacturer IPEX in 2005.
So how to tell if your plumbing lines are Kitec?
There may be a number of clues to determine if your home is plumbed with KITEC lines, however there is no substitute for an assessment by a licensed plumber:
In some cases, a notice may be found on the electrical panel stating that Kitec was used in the home and that the electrical system should not be grounded to it.
Look for the series of orange and blue pipes (although other colours were also used) in visible areas of the home (near the water heater or under sinks are good places to look)
Look for the letters KITEC or KTC stamped on the brass fittings.
The plumbing lines may be labelled with the word Kitec.
