OVERFLOW FITTINGS TO SUIT 100/150mm OUTLETS

100/150OF

Due to the fact that some roof areas are not subject to the best of maintenance regimes, especially when they are completely hidden from view, there are occasions when blockage of the roof outlets can cause a potentially disastrous build up of water. Caroflow Overflow Units are designed to alleviate this problem by sealing the outlet (sold separately) so that it will only come into operation when a build-up occurs. A length of heavy duty PVC pipe is factory bonded to a sealing plate so only when the water has reached a pre-determined depth will it then begin draining and give a warning against build-up. The PVC tube, once installed, is then easily cut to a height lower than the surrounding membrane flashing, and is kept free and clear with a securely fixed domical grating assembly that cannot be removed without the necessary tools. Overflow units come in two sizes, with one to suit the 50mm & 75mm outlets and the other for the 100mm & 150mm outlets.
