<p>A sewer flushing device (20) for location in a sewage system. The device comprises a housing (21) adapted for location in a sewage flow path (14) and a gate (22) pivotally supported on the housing (21) and movable between open and closed positions. The gate is biased towards its closed position so as to inhibit the flow of sewage and thereby cause a build up of sewage. In this way, when the sewage upstream of the gate (22) reaches a predetermined level the gate is urged to its open position such that a flushing pulse of sewage flows downstream. There may also be provided a locating device (23) for holding the housing (21) in the required position within the sewage system. The locating device may comprise a sewer engaging portion (51, 52) adapted to locate in a sewer channel (12, 14), and a housing connector (54) adapted to connect to the housing (21).</p> |
