This is the smaller version of the 4-inch model it is used in sewers that have been repaired using a drain liner or insert or using a smaller pipe it is ideal for 90mm – 98mm pipes. It is compact and provides the same protection as all our other rat flaps.

The valve does not come with the nut and bolt this is for deep chamber installation and can be purchased from us if required please see our other items. The valve is push fit in design and in a chamber which is not deep you can simply compress the valve body and insert it into the outlet and it will clamp to the inside of the chamber (No fitting kit is required).
We are pleased to announce the availability of our new fitting kits for installing our valves at depth.
