Abstract

A method of detecting and identifying leaks in a pipeline on a manifold that connects to a leaking underground pipe for properties having a slab or other type of foundation with a plurality of manifolds utilized to distribute water. The method includes turning off the water to the main water entrance of the property. Next, the method includes identifying a first manifold to test after waiting a period of time, heating up each pipeline evenly, and comparing the temperature of the pipelines that were heated. If a pipe has a leak, the water remaining in the pipe will drain towards the underground leak and will not remain in the pipe, and the exterior of the pipe will be hotter than a pipe containing any water. In this way, the method discloses identifying a pipeline of a manifold that leads to an underground leak.

Claims (23)

1 . A method for identifying an underground pipe containing a leak at a property, comprising:

a. ensuring that a main water inlet valve to the property is shut off and that potable water is not able to flow into the property if any water fixtures are opened or turned on;

b. identifying a first manifold to test on the property, wherein the first manifold comprises a set of manifold pipelines to begin testing to identify a location of and detect the underground pipe containing the leak at the property;

c. optionally cleaning each manifold pipeline of the set of manifold pipelines;

d. heating up each manifold pipeline of the set of manifold pipelines evenly using a heating tool;

e. after heating up each manifold pipeline, reading a temperature of each manifold pipeline and comparing the temperature of each manifold pipeline to each other;

f. if a single manifold pipeline of the set of manifold pipelines of the first test manifold is hotter than other manifold pipelines of the set of manifold pipelines, determining that the single manifold pipeline does not contain water which is an indication that that any water remaining in the single manifold pipeline has escaped through the single manifold pipeline to the underground pipe containing the leak on the property;

g. marking the single manifold pipeline of the first manifold with a visible marker;

h. if the single manifold pipeline of the set of manifold pipelines of the first test manifold is not hotter than the other manifold pipelines of the set of manifold pipelines, determining that all of the manifold pipelines of the set of manifold pipelines of the first test manifold contain water even when the potable water to the property is shut off and that the first manifold does not include a manifold pipeline leading to the underground pipe containing the leak at the property;

i. repeating steps (c)-(f) on additional manifolds on the property to test until identifying a correct manifold having a detected manifold pipeline that reads hotter than other manifold pipelines of the correct manifold after being heated;

j. identifying the detected manifold pipeline of the correct manifold as leading to the underground pipe containing the leak at the property; and

k. marking the detected manifold pipeline of the correct manifold as leading to the underground pipe containing the leak at the property.

2 . The method of claim 1 , wherein the heating tool comprises a torch, a heat gun, or another heating tool.

3 . The method of claim 1 , wherein reading the temperature in step (E) further comprises using touch, vision, or temperature testing equipment.

4 . The method of claim 3 , wherein the temperature testing equipment further comprises using thermometers, cameras, or temperature readers.

5 . The method of claim 3 , wherein using touch further comprises:

feeling each manifold pipeline in a manifold with a user's hands or other part of the user's body to assess the temperature of each manifold pipeline.

6 . The method of claim 1 , wherein identifying the first manifold to test in step (B) further comprises:

checking for any clear signs of where the leak could be located and proceeding to an identified location on the property having the water fixtures and manifolds closest to a location of the any clear signs, wherein the any clear signs comprise flooding, pooling water, warm floors, hissing noises that can be heard with a user's bare ears, or a loud sound detected using audio equipment.

7 . The method of claim 1 , further comprising using audio equipment to identify the first manifold or the additional manifolds to test on the property.

8 . The method of claim 7 , further comprising listening for a loud hissing noise using the audio equipment.

9 . The method of claim 1 , wherein optionally cleaning each pipeline in step (C) further comprises using a file, an emery cloth, a piece of sandpaper, a wire brush, or other tool to clean off any sludge, slime, concrete, plastic or any other unwanted elements that interfere with obtaining an accurate temperature reading.

10 . The method of claim 1 , further comprising utilizing a utility locator to locate pipes located underground a slab or a foundation on the property in order to determine the first manifold to test or the additional manifolds to test on the property.
