Abstract
A blocked sewer unit includes a substantially impermeable barrier having a first side exposed to the interior of a sewage network and a second side, the barrier movable in the direction of the second side in response to fluid pressure on the first side. The blocked sewer alert unit includes a transducer separated by the barrier from the sewage network, the transducer configured to generate an electrical signal when the barrier moves into the dry section. The blocked sewer alert unit includes an alarm circuit configured to convert the electrical signal into a user alert.
