Welcome to NAS Fasteners: Plumbing Parts and General Information
This website was designed to help consumers learn more about plumbing fixtures, parts, fasteners and other plumbing related information for weekend warriors that want to tackle plumbing projects.
Plumbing is an essential part of any building, whether it is a commercial or residential setting. It does not need any complex technology to work. As a matter of fact, it follows the simple laws of nature like that of gravity and pressure. Since it caters to water, the central concept of any plumbing system is to contain and distribute it at the same time.
As a homeowner, it is part of your responsibility to get to know how your plumbing system works and what parts and components need regular maintenance and inspection. Generally speaking, a home’s plumbing system is made up of two separate subsystems. The first one will be bringing in freshwater. The second serves as the unit that takes wastewater out. The water that is brought to your home is under pressure so that it can travel in an upwards direction, in corners, and practically every area where it is needed. As water enters the home, it will be passing through a meter, which in turn will register the amount you use. There’s a switch called the main water shutoff valve located close to the meter. The main purpose of this valve or switch is to be able to stop the water supply during a plumbing emergency.
Water that comes from the main supply is ready for cold water use. However, there is a need for additional equipment in order to produce hot water. For instance, a pipe will be carrying water from the cold water system to the water heater. The hot water line will then be carrying the heated water from the heater to the fixtures, appliances, and outlets that will need it.
A typical home will be using either a sewer or septic system for drainage. Any type of drainage systems don’t really depend on pressure, which makes the different to that of supply systems. This system works differently. Waster matter will leave your home because the drainage pipes are all pitched, angled, or downward. Gravity is the only thing needed in order to pull the waste. The last line of the system is the sewer line that continues the downward flow to the septic tank or a sewage treatment facility. Although the entire system looks pretty simple, it is actually more complex. There are vents that allow air to enter the drainpipes and traps that prevent sewer gas from backing up into the house.
Meanwhile, the supply and drainage subsystems are two very different operations. Also, there is no single component that overlaps between them. However, it is common to see bridges and these bridges are the reason why the plumbing system is essential. In the traditional plumbing terminology, every bridge between the supply and the drainage system is called a fixture.
If you don’t know what a fixture is, you at least are familiar with terms like toilets, tubs, and sinks. All of them are actually the fixtures we’re talking about. Essentially, all kinds of devices that draw freshwater and then discharge wastewater are called a fixture. The main purpose of a fixture’s design is to keep the supply and drainage systems always separated. There are fixtures with individual supply shutoff valves, the purpose of which is for you to no longer have to close the main shutoff when fixing them. Everyone in the family must know the location of the main shutoff valve in order to make sure anyone can shut it off in case of plumbing emergency.
Please understand that before you start learning how to perform plumbing repairs on your own, you have to turn the water supply off to the fixture or better yet do it on the main shutoff valve. Also, if you are looking at adding or changing some pipe in your plumbing system, you have to double check with the local plumbing code. There are regulations that lay out the things allowed and prohibited in plumbing installation and repair.
There are currently many different types and categories of plumbing parts. Though plumbers are the ones who come with the responsibility of knowing and learning all those parts, it makes perfect sense if you the homeowner will also learn them.
The pipes make up a huge part of the entire system. Pipes come in different shapes, sizes, and materials. The accessories used in handling pipes include pipe cutters, drain wrenches, PVC cement, pipe tape, faucet heads, knobs, and others. Today, PVC pipes are the most common variety. They’re also the most preferred because they are lightweight yet strong. More importantly, PVC pipes are affordable. Copper piping is another part, though it isn’t as popular to that of PVC, mainly because of its expensive price tag. It is often used in fixtures and pipes intended for kitchens and bathrooms.
Finally, there is a bunch of accessories and tools involved in plumbing that you also need to know and learn how to use. There are things specifically intended for connecting different types of piping successfully, including PVC cement and plumbing tape. Drain wrenches for their part are intended to fit into very tight spaces to reach hardware secured within them. Plumbing snakes are used to run down into a drain for clearing out clogs. Faucet heads and knobs on the other hand are for finishing off a faucet.
You’ll see that learning plumbing and being able to fix common problems yourself is kind of rewarding. Apart from the fact that it is fun it also helps you save a lot of money on the small and manageable repairs.
