A breacher is usually the tap most outside of a water pipe. It allows the water flow to be controlled prior to entering a device.
The primary function of the breacher is to reduce water flow velocity and pressure. The chief reason for this is that it protects inanimate objects from damage when they are in close proximity to the pipe. A breacher in plumbing helps distribute water throughout an entire building or house. Breachers can come with or without handles, making them different valves. When there is no handle, then it closes completely when rotated all the way counterclockwise. It does not allow water to flow. Handleless valves are often called gate valves. As with other plumbing system parts, breachers break, leak, and require repair.
A breacher in plumbing is similar to shut off valves and stop valves because they all serve the same basic function; they control water movement throughout a building or house. The difference between these three types of plumbing fixtures is that while the shut-off valve and stop valves do close completely when rotated all the way counterclockwise, they maintain some level of water flow. In contrast, a breacher allows for no such flow through it at all.
The different types of breachers come round or square-shaped. They can have long necks, where the head meets the base of the valve or very short necks. Each style of breacher comes with a different type of handle. The long neck or gate valve does not have any handles attached to it, and the shorter neck or non-gate valve has one open end used to control water flow.
Plumbers may need to install a breacher if you are experiencing a leaking shower or tap washer. Leaks could have occurred after the tear and wear caused by the expansion, contraction, and constant pressure of the hot and cold water mains. You may also have to install a breacher in case you want to renovate or modify an old bathroom or sink pipework. For this repair job, you or your plumber will need the right tools to install, fix or do repairs to a breacher. A breacher is a plug-type valve, which means that once installed, it cannot be removed without cutting the pipe.
Turn off the water supply to the taps.
Select location for new fixture and mark with a pencil on the wall.
Remove cover from new fixture to expose piping.
Loosen two compression nuts within exposed piping as far as they will go by hand or wrench until there's no more resistance. A vice grip can also be used if necessary. These are located below and above, where the nut will be tightened later. The Teflon tape that came wrapped around the threads of the new valves should also be removed before proceeding any further.
Remove the entire compression ring from the valve.
Slide the valve into the piping before closing off both openings with your hand to avoid water spills.
Once fully seated, tighten compression nuts by hand until snug. If using a wrench, ensure that it's tight enough to prevent leakage but not so tight that you crack or split the product. Then wrap Teflon tape clockwise over each nut several times and finish with another compression ring to secure in place. Make sure valves are also completely closed when completing the installation process.
A breacher can be tested by rotating it counterclockwise all the way and allowing it to sit like that overnight. This will ensure that there is no leakage when water pressure rises throughout the day. If there's no noticeable leakage, then the valve has passed successfully.
A T-shaped fitting must be installed prior to the installation of each fixture. It is important to take extra precautions and not forget this step, or there will be no way for water to flow into the fixture. If you want to do the installation job in person, follow the below steps.
Turn off the water supply.
Unscrew a small portion on top of the new faucet with an adjustable wrench until it comes completely loose. Some fixtures may have plastic or metal mounting nuts that can be removed by hand instead. These will need to be replaced later when finishing up your modifications.
Remove cover from exposed pipework and loosen compression nut using adjustable equipment such as a wrench or vice grips approximately three-quarters of the way around if possible. Again, some fixtures may only have plastic or metal mounting nuts that can be removed by hand. This nut must also remain loose until the end of this step.
Once the small portion at the top is completely detached from the main fixture, tighten the compression nut with an adjustable wrench or vice grips, ensuring it's evenly tightened around all sides to prevent leakage. Failure to do so could result in a broken product and serious damage if water leaks inside the wiring during the installation process. Make sure not to over tighten as this will damage the swivel mechanism.
Once all bolts are secure, re-tighten the compression nut with a piece of adjustable equipment and replace plastic/metal mounting nuts if necessary. Make sure to tightly screw these down as well, so there is no leeway for them to become loose and cause a clog or leak after installation.
