The clean-out cap locator forms a cap that encloses a clean-out plug. The clean-out cap locator comprises a threaded cap, a control circuit, a remote control, and a personal data device. The control circuit determines the GPS coordinates of the control circuit. The control circuit transmits the GPS coordinates of the control circuit to the personal data device. The control circuit generates an audible alarm indicating the location of the clean-out cap locator. The control circuit senses the flow of fluid around near the clean-out cap locator. The control circuit transmits an alarm to the personal data device when the control circuit senses a back-up in the clean-out plug. The control circuit generates an audible alarm when the control circuit detects a back-up in the clean-out plug. The remote control sends a signal to the control circuit that causes the control circuit to generate an audible alarm.

A nozzle cap spacer for a hydrant nozzle cap includes a spacer body defining an outer body edge, the spacer body defining a spacer body thickness; and a resilient first spacer spring arm extending from the outer body edge and biased away from the spacer body in an extended orientation, wherein the first spacer spring arm defines a first spring arm thickness; wherein the first spring arm thickness of the first spacer spring arm is equal to the spacer body thickness of the spacer body.

A fire protection system can include one or more pipes coupled with a fluid source, a pipe fitting coupled with the one or more pipes downstream of the fluid source, and at least one sprinkler coupled with the one or more pipes and the pipe fitting. The pipe fitting can include a wall defining an opening, the wall having an outer diameter, a first wall thickness at the opening, and a second wall thickness inward from the opening, the second wall thickness greater than the first wall thickness. The at least one sprinkler can be coupled with the one or more pipes and the pipe fitting to receive fluid from the fluid source through the one or more pipes and the pipe fitting.

A thread protector that has an external sleeve having threads disposed on an inner side to engage with pin threads disposed on a pin end of a tubular member. The thread protector also has a flange disposed on a first end of the external sleeve to engage with the pin end of the tubular member, the threads on the inner side of the external sleeve are disposed axially adjacent to the flange and radially adjacent to the end of the pin end of the tubular member. A method of protecting the pin threads of the pin ends of the tubular members. The method includes screwing the thread protector on the pin threads of the pin end of the tubular member.

The present invention includes: a first part (11) which has a hollow cylindrical shape and circumscribes or is inscribed in a pipe (26); and a second part (15) which has a cylindrical shape and circumscribes or is inscribed in the first part (11), wherein inclined portions (23), which have inclination angles that can hinder the second part (15) from retreating from the first part (11), are formed between the first part (11) and the second part (15) so as to correspond to each other. That is, when a pipe sealing device is mounted to the pipe and the second part (15) is retreated from the pipe (26), the inclined portion (23) of the first part (11) and the second part (15) push against each other, the first part (11) is pressed against and fixed to the pipe, and the second part (15) can no longer retreat from a limited line due to inclination angles. Connecting or closing pipes typically involves making screws or welding, and thus requires many tools and consumes much time. In contrast, such work can be conveniently performed using the pipe sealing device of the present invention. Also, a fluid inlet and outlet portion (43) is provided, and thus a pipe sealing test can be easily performed for each section.

A pest control assembly is configured to prevent pests from entering a structure. The pest control assembly has a plumbing system, with a drain line joined to a first cleanout. A ledge is arranged on the first cleanout. A pest control insert placed upon the ledge and further comprising a cylindrical body further having a plurality of openings are arranged upon an upper half of the cylindrical body. A chlorine gas emitted from the cylindrical body through the plurality of openings prevents pests from entering the structure.

A plug for a pressure test configured for a tubular component, the tubular component including a male threaded element at a free end, the male threaded element including a male thread and a sealing surface, the plug including a thread compatible with the male thread, an inner annular groove, and a sealing ring held in the groove such that the sealing ring is radially compressed between an outer periphery of the male threaded element and a bottom of the inner annular groove.

Cleanout conduit valve assemblies for a cleanout conduit may include a vertically oriented valve housing. The valve housing may include a valve inlet end configured to be disposed in fluid communication with the cleanout conduit and a valve discharge end opposite to and generally above the valve inlet end. The valve discharge end may be oriented within a valve discharge plane disposed at a discharge angle of greater than 0 degrees with respect to a horizontal plane. The valve discharge end may have an upper discharge opening side and a lower discharge opening side sloped downwardly from the upper discharge opening side. A valve body may be pivotally carried by the valve housing at the upper discharge opening side of the valve discharge end. Methods of preventing precipitation and runoff on a ground surface from entering a cleanout conduit connected to a sewer service line are also disclosed.

A sealing compression ring apparatus couplable to a liner and a pipe component has an annular body and a bore, with a first side including a raised outer edge portion, a recessed annular portion between the raised outer edge portion and the bore, and an o-ring gland encircling the bore on the recessed annular portion. A pipe assembly has a base pipe including a flange, a liner extending axially within the base pipe and extending radially out and over a portion of the flange to define a liner flange, an opposite flange surface, and a sealing compression ring apparatus compressed between the flange and the opposite flange surface, and an o-ring positioned in the o-ring gland of the ring.

According to one aspect of the invention, a tool and a method of sealing a hole in a pipe is provided. The tool includes a first portion configured to form a first thread in the hole. A second portion adjacent the first portion is provided having a second thread, the second thread configured to engage the first thread. A third portion adjacent the second portion is provided opposite the first portion. The third portion being sized larger than the hole and having a feature configured to engage an installation tool. A seal is arranged between the third portion and the pipe when the tool is installed in the hole.
