Using Plumbing Fittings Using Plumbing Fittings
When building or repairing equipment such as a sink or a plumbing system, using plumbing fittings is essential to get the pipes to go to the proper places leak free. There is a wide variety out there of plumbing fittings for many different uses. Some are made of copper, some of PVC plastic and others are threaded and come in all kinds of size and shapes. Lets take a look at the three main kinds of plumbing systems and fittings.
Copper fittings are available in 1/2, 3/4 or 1 inch in diameter. Elbows are used to change water lines directions and can be found in 45 or 90 degree angles. Tees are used to connect to water lines together and pieces called couplers are used to extend whole copper pipes sections. Copper fittings and pipes don't come threaded and do not need glue to be assembled. They have to be bounded together using heat and solder.
Since copper pipes often need to repaired in small corners and under wood beams, extra caution must be taken when heating them with a torch. A fire could begin very quickly while doing such repair. Most of the time leaks happened at the junction where the copper fittings have been soldered, which create problems after many years.
Copper fittings are use to help fix and replace components of old copper plumbing systems only. Many years ago plumbing systems were only made of copper and still today older houses are relying on this type of pipes. An older copper plumbing system could be a real problem for a home owner as the old soldered junctions begin to leaks. Most of the time leaks happened at the junction where the copper fittings have been soldered.
Fittings comes in sizes of 1/2 to 4 inches and in the whole range of tees and elbows, cross and straight pipes. PVC pipes are made of hard, sturdy plastic that never rusts. The fittings have to be assembled using a primer that you let dry for 10 minutes before applying glue. It takes at least an hour to dry before water can run down the pipes. Letting water go in too soon may cause the junction to leak.
Thanks to the invention of PVC pipes, dwellings don't have to rely on copper plumbing systems anymore, which need to be completely replaced after 30 years. Newer constructions are now equipped with PVC plumbing systems that never rust and are a lot easier to fix in case of leaks.
Threaded fittings also comes in different sizes but are usually made to use with gas lines. Installing them is a little tricky since there is no glue or soldering needed. Spraying a mix of water and soap on a threaded fitting can help to determine if the fitting is leaking. If it bubbles, the fitting needs to be tightened a little more. Caution should be used not to overtightened it to prevent damages to the threads.
