Overflow Outlets

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.

Our Overflow units come in two sizes, with one to suit the 50mm & 75mm outlets and the other for the 100mm & 150mm outlets.

The codes and dimensions of these are as follows;
