If you require a trapped sump unit because your outlet pipe is connecting to a combined system (includes foul water) ACO would strongly recommend installing a foul air trap in conjunction with the sump unit.
The foul air trap simply pushes into the outlet on the sump unit, your outlet pipe then connects onto the foul air trap using either a standard 110mm or 160mm diameter PVC-U connector.
This procedure will prevent foul smells from backing up within your system. ACO offer a standard version #920 (110mm) and #922 (160mm) or a roddable version #940 (110mm) and #950 (160mm). Please note, roddable foul air traps are manufactured from MDPE (medium density polyethylene).
