Abstract

Semi-automated testing devices for a plumbing stack are disclosed. A semi-automated testing device in accordance with the present disclosure may comprise a transfer pump configured to automatically fill the plumbing stack; at least one automated gripping element configured to grip a supplemental pipe coupled to a pipe of the plumbing stack via a connection; at least one automated sealing element configured to seal the connection; and at least one sensor configured to measure a water level of the supplemental piping. A method of testing the plumbing stack with the semi-automated testing device is also disclosed.

Claims (29)

1. A testing device for a plumbing stack, the testing device comprising:

a transfer pump configured to automatically fill the plumbing stack;

at least one automated gripping element connected to a testing device structure, configured to grip a supplemental pipe coupled to a pipe of the plumbing stack via a connection, and configured to secure the supplemental pipe to the testing device structure;

at least one automated sealing element configured to seal the connection; and

at least one sensor configured to measure a water level of the supplemental piping.

2. The testing device of claim 1 , wherein the at least one automated gripping element comprises a two finger clamp and a single finger clamp.

3. The testing device of claim 1 , wherein the at least one automated sealing element comprises a first pipe seal for a first connection diameter.

4. The testing device of claim 3 , wherein the at least one automated sealing element further comprises a second pipe seal for a second connection diameter and a third pipe seal for a third connection diameter.

5. The testing device of claim 1 , wherein the at least one sensor comprises a body portion coupled to the supplemental piping.

6. The testing device of claim 5 , wherein the at least one automated level sensor comprises a bobber sensor located in the body portion.

7. The testing device of claim 6 , wherein the body portion includes a clear portion for viewing the bobber sensor.

8. The testing device of claim 6 , wherein the bobber sensor is coupled to a pipe via a coupling element.

9. The testing device of claim 8 , wherein the pipe is coupled to an adjustable bracket.

10. The testing device of claim 9 , wherein a height of the adjustable bracket is adjustable via a screw configured to be threaded in the body portion.

11. The testing device of claim 1 , wherein a body portion of the sensor is coupled to a pipe element configured to receive an overflow of water from the supplemental piping.

12. The testing device of claim 1 , wherein the plumbing stack comprises a plurality of pipes and there is at least one sensor for each pipe of the plurality of pipes of the plumbing stack.

13. The testing device of claim 1 , wherein the plumbing stack comprises a plurality of pipes and there is at least one automated sealing element for each pipe of the plurality of pipes of the plumbing stack.

14. The testing device of claim 1 , wherein the plumbing stack comprises a plurality of automated gripping elements.

15. A method of testing a plumbing stack comprising:

receiving the plumbing stack;

securing the plumbing stack to at least one automated gripping element of a testing device, the at least one automated gripping element connected to a testing device structure and configured to secure the plumbing stack to the testing device structure;

securing the plumbing stack to at least one automated sealing element of the testing device; and

starting an automatic test cycle, the automatic test cycle triggers a transfer pump to fill the plumbing stack to a water level sensor of the testing device;

monitoring the water level sensor; and

determining whether the plumbing stack passes or fails based on a reading of the water level sensor.

16. The method of claim 15 , wherein the reading of the water level sensor is at least one of on and off.

17. The method of claim 16 , wherein the plumbing stack passes if the water level sensor is on for a specified time.

18. The method of claim 16 , wherein the plumbing stack fails if the water level sensor turns off during a specified time.

19. The method of claim 15 , wherein the water level sensor includes a bobber sensor configured to measure a level of water.
