There are many critical parts to an outdoor faucet beyond the water spout and handle for functionality.
Although it may be surprising, a typical faucet style on the outside of a home will consist of nine various parts.
The 9 Parts of an Outdoor Faucet

Let’s take a look at the nine different parts that make up an outdoor faucet to give you a better idea of what it entails and how they work together.
1. Supply Pipe

Although the supply pipe isn’t a direct component of the outdoor faucet itself, you can’t get water without it. This pipe comes from behind the wall mount inside the home and allows water to flow to the faucet.
In addition, the supply pipe will often have its own shut-off valve to prevent pipes from freezing and make equipment maintenance and repairs simple.
2. Wall Mount

Naturally, the wall mount is how the faucet securely connects to the home on the outside.
First, it’ll have holes to drill into the house’s exterior to keep it in place. Then, it attaches the faucet housing to the supply pipe from within the home.
3. Faucet Housing and Spigot

Many will refer to the entire faucet housing as a spigot, although that’s technically incorrect.
The spigot is only the end section of the water spout that uses threading to make connecting garden hoses and other attachments easier.
The faucet housing contains four crucial parts that help regulate the volume of water moving through the unit. These parts include the valve seat, stem washer, spindle, and packing washer.
4. Valve Seat

The valve seat sits inside the faucet housing beneath the stem. This critical piece helps regulate how the water flows through by having the stem washer press up against the valve seat.
Full pressure will restrict water completely, while no restriction allows water to flow freely.
5. Stem Washer

The stem washer is at the spindle’s bottom, just above the valve seat.
Rotating the handle right and left will move the stem washer on the spindle up and down to alter how much you want to allow through the faucet.
6. Spindle (Stem)

The spindle, or stem, is the long piece that runs from the handle down through the housing.
It’ll move up and down inside the faucet when you turn the handle to guide the stem washer to the valve seat, allowing or restricting water flow.
Naturally, turning the handle right will securely close the opening for water and restrict any coming out of the spigot.
Rotating the handle to the left will open the valve more, so water can flow freely. Of course, the more the spindle turns and moves up from the valve seat, the more space there is for water to go.
7. Packing Washer

The packing washer sits just below the packing nut at the top of the faucet housing. It’s a small but essential piece of the unit.
It ensures that water does not flow upward and sprays out near the handle when it’s turned on. In addition, it creates an air- and water-tight seal to prevent leaks and corrosion.
8. Packing (Bonnet) Nut
The packing nut, or bonnet nut, is at the top of the housing and is the location where the handle will be secured to the faucet.
It’s typically metal and screws on securely. This piece keeps the handle in place and ensures a solid connection to the packing washer to eliminate potential leaks.
9. Handle

The handle is the top part of an outdoor faucet. Handle styles can vary from a round shape to a long, flat handle.
They are usually made of metal but can come with silicone coatings to help with grip.
Moving the handle right will close the valve seat, preventing any water from flowing, while turning it to the left will allow water to come through quickly.
Things to Consider
If you prefer to complete any repairs or maintenance jobs yourself, knowing what to look for and how to pinpoint issues with outdoor faucets can be helpful.
- Leaking water from the spigot: If tightening the handle on your outdoor faucet doesn’t stop water from dripping, you may have a problem inside the housing. If the valve seat or stem washer fails, they will allow water to trickle through, causing leaks.
- Leaking water from the handle: When water sprays up from where the handle connects to the top of the faucet, you have a problem with your packing washer. These small parts can wear out, causing leaks when you turn on your tap, forcing water up to where the handle connects.
- The handle is too easy to turn: Mechanical parts can break down over time, including the spindle. If the handle is too easy to turn and does not allow water to flow freely as it once did, the spindle may require replacing.
- Handle is difficult to turn: If you are having a hard time turning your faucet on or off, you may have the wrong size spindle for your faucet. Be sure to check all specifications when replacing parts to ensure they can work with your model.
The cost of an outdoor faucet can range greatly, depending on the style and type and whether you require a professional to install it for you or if it will be a DIY project on the weekend.
On average, a relatively inexpensive outdoor faucet will cost around $150, while having a professional install one for you that is a high-end model can run upwards of $500 or more.
Of course, other elements, including shut-off valves and supply pipes, will alter the total cost.

So, What Are the Parts of an Outdoor Faucet?
Although an outdoor faucet contains nine different parts within this small object, it isn’t a complicated system.
Many DIYers can troubleshoot and repair any problems with their outside water source by investigating some common issues.
Knowing the various parts and their functions enables individuals to be proactive when problems occur.
This way, changing out an individual piece will be less costly and less extensive than replacing the entire outdoor faucet.
