Metalwork in Plumbing

Copper is the most common type of metal used in plumbing because it is corrosion-resistant, durable, and easy to work with.

A flux is used in soldering to clean the metal surfaces, prevent oxidation, and improve the flow of solder.

Sweat joints are made by heating the metal with a torch and then joining the two pieces together, while solder joints are made by melting solder onto the metal surfaces and then joining the two pieces together.

A trap is a U-shaped pipe that is installed under a sink or toilet. It prevents sewer gases from entering the home, catches debris and prevents it from clogging the drain, and provides a vent for the drain.

PEX (cross-linked polyethylene) is the most common type of pipe used for water supply lines because it is flexible, easy to install, and resistant to corrosion.

A water heater is a device that heats water for domestic use, such as bathing, washing dishes, and laundry.

Gas water heaters are the most common type of water heater because they are relatively inexpensive to operate and can provide hot water quickly.

Water heaters heat water for domestic use, while boilers heat water for a central heating system. Water heaters are smaller than boilers and are less expensive to purchase and install.

A pressure reducing valve is a device that is installed in a plumbing system to reduce the water pressure. This can help to prevent water leaks and improve the flow of water.

PVC (polyvinyl chloride) is the most common type of drain pipe because it is lightweight, easy to install, and resistant to corrosion.

A cleanout is a small opening that is installed in a drain pipe to provide access for cleaning. This can be done with a snake or a chemical drain cleaner.

Elbows are the most common type of fitting used in plumbing because they are used to change the direction of a pipe.

Valves are used in plumbing to control the flow of water. This can be done by opening or closing the valve.

Ball valves are the most common type of valve used in plumbing because they are easy to operate and can be used to control the flow of water in both directions.

Backflow preventers are devices that are installed in a plumbing system to prevent water from flowing back into the water supply. This can help to prevent contamination of the water supply.
