The Multikwik traps range has been created with and by plumbers to ensure all the typical installations and installer preferences can be met. For a fuss free 'no call back' installation we ensure... - Our compression nuts have been designed to be easily hand tightened and the connection is compatible with most plumbing pipe size and materials. - We only use high quality components including, but not limited to our compression nuts, slip ring and EPDM profiled rubber seal – these all ensure a secure watertight joint. - All traps have been designed to have smooth, clean, internal surfaces that will facilitate self-cleaning and avoid debris build-up. - We try to design our products to save you time on site, so all our traps have unique slip ring colours to aid size identification: Blue 32mm Red 40mm White 50mm 40mm Washing Machine Utility Double Nozzle Trap
