The standard water supply line sizes used in residential plumbing systems are typically 1/2 inch or 3/4 inch in diameter.
The purpose of a 1/4 inch inline shut off valve is to control the flow of water in a plumbing system. It is used to stop or regulate the flow of water to a specific fixture or appliance, allowing for maintenance or repairs to be done without shutting off water to the entire system.
An offset P-trap in plumbing systems is used to prevent sewer gases from entering a building while allowing wastewater to flow out.
Plumbing pipe dope is used to seal and lubricate threaded connections in plumbing systems. It helps create a tight seal to prevent leaks and also makes it easier to tighten and loosen connections. The purpose of using pipe dope is to ensure a secure and leak-free connection in plumbing systems.
An offset drain in plumbing systems is used to redirect the flow of water around obstacles, such as beams or walls, to ensure proper drainage and prevent clogs.
A drain saddle is used in plumbing systems to connect a water filtration system or water softener to a drain pipe. It serves the purpose of allowing the system to discharge wastewater safely and efficiently into the drain without causing any leaks or blockages.
The purpose of a PVC cleanout plug is to provide access to the plumbing system for cleaning and maintenance. It is used to seal off a cleanout opening in the plumbing system, allowing for easy removal when needed to clear clogs or inspect the pipes.
A dresser coupling for galvanized pipe in plumbing systems is used to connect two pipes together securely and prevent leaks. It provides a tight seal and helps maintain the integrity of the plumbing system.
A 4-way PVC elbow in plumbing systems is used to change the direction of flow in four different directions. It helps in connecting pipes at right angles and allows for the creation of complex plumbing configurations.
An external plumbing cover is used to protect outdoor plumbing systems from weather elements such as rain, snow, and UV rays. It helps prevent damage and corrosion to the pipes, fittings, and other components of the plumbing system, ultimately extending its lifespan and ensuring proper functioning.
I have never seen a stapler used for any plumbing purpose.
A double P-trap in plumbing systems is used to prevent sewer gases from entering a building. It creates a water seal that blocks the gases from coming back up through the drain.
