Brett Martin;s multifit drainage fittings work with other manufacturers’ products
Brett Martin’s twinwall multifit drainage fittings can now be used with other manufacturers’ polyethylene fittings without losing BBA certification for the whole system.
Previously, mixing fittings would invalidate the BBA certification. The Brett Martin multifit fittings are part of the company’s surface water drainage range. It consists of 24 fittings that are certified to fit any other manufacturer’s BBA-certified polyethylene 150mm, 225mm and 300mm diameter twinwall fittings.
