The Buffalo valve is easy to fit and operates in 150mm or 6" plastic or clay pipes.

This valve is a universal fit product due to its unique design and also has an intergrated mechanism to allow it to be locked watertight.

With the stainless steel flap it is also rodent resistent.

Typically installed in the last access chamber before the sewer to prevent backflows affecting the drainage of the dwelling.

Should only be pushed into the upstream connection / inlet to the manhole, do not fit into the downstream / outlet from the chamber.

Suitable for most situations as long as the flap usually can swing clearly.
