Features a removable inner sleeve to make cleaning easy and creating access for rodding. This sleeve also creates a space between itself and the wall of the gully, forcing the water up to reach the outlet pipe, whilst trapping the water to prevent odours escaping.
For use with 110mm rainwater or greywater drains before connecting to foul or combined drainage systems. Back inlet allows for connection to an existing run (supplied with 1 x blanking plug if back inlet connection not required).
