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.

Claims (19)

1. A blocked sewer alert unit, the blocked sewer alert unit comprising:

a substantially impermeable barrier, the barrier having a first side exposed to the interior of a sewage network and a second side, the barrier movable in a direction of the second side in response to pressure on the first side;

a transducer separated by the barrier from the sewage network, the transducer configured to generate an electrical signal when the barrier moves in the direction of the second side;

an alarm circuit configured to convert the electrical signal into a user alert;

a housing, the housing further comprising:

a terminal section containing the substantially impermeable barrier, the transducer, and the alarm circuit;

a connector operatively connecting the blocked sewer alert to the sewage network; and

a section of pipe disposed between the terminal section and the connector, the section of pipe including a first opening connected to the terminal section and a second opening connected to the connector, wherein the section of pipe further comprises a cleanout port adjacent to the first side of the barrier and disposed between the first opening and the second opening;

a length of pipe operatively connected to the cleanout port, the length of pipe terminating in an exterior opening;

a valve in the length of pipe, the valve having a first state in which the valve prevents flow from the cleanout port to the exterior opening and a second state in which the valve permits flow from the cleanout port to the exterior opening.

2. The blocked sewer alert unit of claim 1 , wherein the transducer further comprises a switch that generates an electrical signal when the barrier moves in the direction of the second side.

3. The blocked sewer alert unit of claim 2 , wherein the switch is a reed switch, and further comprising a magnet attached to the second side of the substantially impermeable barrier.

4. The blocked sewer alert unit of claim 1 , wherein the transducer further comprises a pressure sensor.

5. The blocked sewer alert unit of claim 1 , wherein the transducer generates the electrical signal upon an increase in pressure resulting from a sewage level in the sewage network reaching the barrier.

6. The blocked sewer alert unit of claim 1 , wherein the alarm circuit further comprises a data connection to a remote device.

7. The blocked sewer alert unit of claim 1 , wherein the exterior opening further comprises a plumbing connector.

8. The blocked sewer alert unit of claim 1 , wherein the connector is operatively engaged to a pipe in the sewage network.

9. The blocked sewer alert unit of claim 1 , wherein the connector is operatively engaged to a sewage cleanout.

10. The blocked sewer alert unit of claim 1 , wherein the transducer further comprises at least a pressure sensor.
