A faucet’s supply line size is based on the pipe’s inside diameter and the desired flow rate. The most common diameters are 3/4″, 1/2″, and 3/8″. The inside diameter of the supply line must be greater than the outside diameter of the inlet.
For a standard kitchen faucet, the supply line size should be 1/2 inch.

What size are standard faucet supply lines?
There are a few different types of faucet connectors, but the two most common are 3/8- and 1/2-inch compression or male pipe thread connectors. These are typically the standard size for most faucets, but it’s always best to check the specific requirements for your faucet before making a purchase.
To measure the outside diameter (OD) of your pipe or pipe fitting, wrap a string around the pipe and mark the point where the string touches together. Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference). Divide the circumference by 314159.
How many fixtures can a 1/2-inch water line supply
The number of fixture units that a pipe can support depends on the size of the pipe. For example, a 1-inch pipe can support up to 30 fixture units, a 3/4-inch pipe can support up to 14 fixture units, and a 1/2-inch pipe can support up to 4 fixture units.
If you have a small house with few people, then a 3/4 supply may be all you need. However, if you have a large house with many people, then you may need a bigger supply.
What size are Moen supply lines?
Moen faucets typically have either flexible supplies with ⅜” compression fittings or ½” IPS connections. This makes them easy to install and allows for a wide range of installation options.
Plumbing fittings are commonly referred to as “NPT”, however, in reality, nearly all faucets are actually “NPS”. NPS is the North American “STANDARD” for faucets, regardless of brand, style, application, etc. The main difference between NPT and NPS is the taper of the threads. NPT has a tapered thread, while NPS has a straight thread.
Whats better 1 2 or 3 4 water line?
If you have a 1″ trunk and branch system, you may as well put the kettle on because you have all that extra water volume and reduced flow. However, if you use a cheaper crimp fitting, you may not have enough water volume.
A typical one family house is supplied by a 1″ water service line. This is the typical size line required for most houses. If you have a larger home or one with multiple levels, you may need a larger supply line.
What is 3 8 copper pipe used for
Copper tubing is the best choice for air conditioning and refrigeration because it is durable and easy to connect. Copper is a non-corrosive metal that does not leach chemicals into the air stream like some other metals. It is also a good conductor of heat, which helps the air conditioning and refrigeration system to work efficiently.
There is a lot of misinformation out there about water pressure and piping. Many people believe that installing larger pipes will increase water pressure. This is simply not true. Water pressure is determined by the municipal water system, not the size of your pipes. If the water flowing through your pipes isn’t up to the necessary flow, then increasing the size of your pipes won’t help. In fact, it could actually make things worse.
How many GPM can a 1/2 pipe handle?
The table above outlines the approximate water flow (measured in gallons per minute and gallons per hour) for various pipe sizes under average pressure conditions. The flow velocity is also provided for reference.
One-half inch is the standard size for most residential water supply pipes, but some tub and shower faucets require a three-quarter inch diameter pipe. Check the manufacturer’s specifications to be sure. Larger pipes can carry more water, but they cost more and are more difficult to install.
Is 3/4 PEX big enough for main water line
If you are replacing old water supply lines, it is a good idea to use PEX piping. The standard is to use the same size plumbing, although you can transition from 3/4-inch to 1/2-inch plumbing with an adapter. PEX piping is available in 1/2-inch and 3/4-inch diameters. For adequate water flow, use 1/2-inch or 3/4-inch PEX.
PEX tubing is a type of plastic tubing that is commonly used in plumbing and radiant heating applications. PEX tubing comes in a variety of sizes, and is typically made of a high-quality plastic material. PEX tubing is durable and flexible, and can withstand a wide range of temperatures. PEX tubing is easy to install, and is less likely to leak than traditional plumbing materials.
Can PEX be used for main water line?
PEX tubing is often used in new home construction, as it is more durable and flexible than copper or CPVC piping. However, you can also use PEX tubing to connect to the main water supply line from the curb. This can provide a more efficient connection and reduce the amount of potential leaks.
Polyvinyl chloride (PVC) pipe is a popular choice for new water main applications for several reasons. PVC pipe is less expensive than other types of pipe, it is durable, and it is lightweight. PVC pipe is also easier to install than other types of pipe, making it a good choice for many applications.
Final Words
The most common size for a faucet supply line is 3/8 inch.
There are a few factors to consider when selecting the size of your faucet supply line. The most important factor is the flow rate of your water. A higher flow rate will require a larger supply line. You should also consider the distance the water has to travel from the supply line to the faucet. A longer distance will require a larger supply line.
