Galvanized pipe is metal coated with zinc to protect it against corrosion and rust. It used to be the standard for plumbing in industrial properties and homes, but isn’t employed now for drinking-water supply lines. Its zinc coating may include traces of direct as well as in areas with water that is hard, like much of California, it’s subject to some buildup of mineral deposits. Most plumbing codes now need copper or polyvinylchloride (PVC) pipe for potable water. Pipe continues to be used in sprinkler methods and certain plumbing applications, including drains, vents and out-door water.
Install galvanized pipe with fittings and threaded connections. Pipe ends have threaded ends that are screwed in to different kinds of fittings or feminine connectors. Pipe lacks the versatility of plastic or copper tubing and have to be cut and joined to make turns or bends.
Use T connectors to create a branch off a main-line, Y joints where a single-line is straight-line or divided into two connectors of the same or various dimensions. Cut pipes to appropriate lengths using a ring or a hack saw -kind pipe cutter. The blade is rotated frequently till the pipe is cut through by it. This makes a cut that is cleaner than a hack-saw.
Make connections by placing a lubricant or “pipe dope” to the male threads, Fasten the two ends yourself, turning the male pipe at least two complete turns to the connector to create sure it’s threaded properly. Complete the experience of a pair of wrenches, one to support the the pipe that is the feminine the other to to show the pipe that is male.
Joining to Copper
Join galvanized and copper pipes with connectors, which mix metal and copper components. A union that is dielectric features a large nut which fastens a brass or copper tube into a steel pipe on the side that is other. Brass or the copper is soldered then the connector is secured by the nut . Copper and galvanized are often joined at outside taps, water-heaters and plumbing installations that were related.
Drain and Vents
Even though PVC has absorbed these installations in the majority of houses pipe continues to be used for vent pipes or plumbing drains. Bigger pipe is used by these programs. Pipes come in sizes from 1/8 inch to 5″, measured on the within dimension. Water pipes are typically 1-inch in diameter, vent and drain pipes are generally typically or 3 inches. Connect drain pipes to the base of a drain as well as a sink using a metal P-trap. Install vents through the roof using a rain cap or an elbow in the leading to block rain from a drain line.
