Even if there is room under the kitchen sink, the waste often travels though the wall too high to enable the a normal stand pipe and trap to be fitted.

To prevent backflow, there is a solution. A standard clamp arrangement can be fitted to the waste pipe (1 1/4" or 1" 1/2"), The Gap Trap can be screwed straight in. This neat little fitting has a trap built in and this stops any smell from coming back through. A 3/8" or 1/2" Air Gap can then be glued on the top. The whole thing only stands 200mm (8") tall and can almost always be fitted under the kitchen sink.

Please note that the low flow option can only handle a flow rate up to 1.6 l/min and this isn't high enough for some softeners. This is caused by the water slowing down as it passes through the trap.

The High flow kits have a larger extension piece that increases the length of the standpipe. At full length the the increased head means that 10l/min can be reached. Attach the Gap Trap as before and then glue the coupler and extension in place.

Please note: The extension piece can shortened to fit the installation but be aware that this will reduce the maximum flow to drain.
