Find out the answer to the question, “What size PEX pipe do you need for a shower?”
Checkout this video:
PEX pipe is a flexible plastic piping used for a variety of plumbing applications. It is available in sizes ranging from 3/8 inch to 4 inches in diameter. The most common size for a shower is 1/2 inch, but the 3/4 inch size is also used in some showers.When installing PEX pipe for a shower, it is important to use the correct size pipe to avoid problems with water pressure and flow.
What is PEX Pipe?
PEX pipe is made of cross-linked polyethylene, which is a type of plastic. It is often used in plumbing applications because it is flexible, durable and easy to install. PEX pipe is available in a variety of diameters, so you can choose the size that is right for your shower. Most showers will require a 1/2-inch or 3/4-inch PEX pipe, but larger showers may need a 1-inch pipe.
Factors to Consider When Choosing the Right Size PEX Pipe
The size of the PEX pipe that you need for your shower will depend on various factors, such as the shower head flow rate and the length of the shower head supply line. You will also need to consider the water pressure in your home as well as the distance from the water heater to the shower head. In this article, we will go over all the factors that you need to consider when choosing the right size PEX pipe for your shower.
The Size of the Shower
The size of your shower will be the biggest factor in determining what size PEX pipe you need. A small shower with one or two showerheads will require less water flow than a large shower with multiple showerheads. The size of the PEX pipe you need will be determined by the amount of water flow your shower needs.
The Number of Shower Heads
If you are planning on having more than one shower head in your shower, you will need to factor this into your decision of what size PEX pipe to use. The number of shower heads will affect the flow rate of water through the PEX pipe. If you have a higher flow rate, you will need a larger diameter pipe.
The table below shows the recommended PEX pipe sizes for various flow rates:
Shower Heads Recommended PEX Size
1 3/4 inch
2 1 inch
3 1 1/4 inch
4 1 1/2 inch
The Flow Rate of the Shower Heads
There are three primary factors to consider when choosing the right size PEX pipe for a shower: the flow rate of the shower heads, the number of showerheads, and the distance from the water heater to the shower.
The flow rate of a shower head is measured in gallons per minute (GPM). The average flow rate for a shower head is 2.5 GPM, but some high-flow shower heads can have a flow rate as high as 5 GPM. To calculate the total flow rate for your shower, simply add up the flow rates of all of the showerheads that will be in use at the same time. For example, if you have two showerheads with a flow rate of 2.5 GPM each, then your total flow rate will be 5 GPM.
The second factor to consider is the number of showerheads that will be in use at the same time. If you only have one showerhead, then you won’t need as much water pressure as someone who has two or more showerheads. In general, each additional showerhead will require an additional 1-2 GPM of flow.
The third factor to consider is the distance from the water heater to the showers. The further away the showers are from the water heater, the larger the pipes will need to be in order to maintain adequate water pressure. For example, if your showers are just 10 feet from your water heater, then ½” PEX pipes would be adequate. However, if your showers are 50 feet from your water heater, then you would need 1” PEX pipes.
When choosing PEX pipes for a shower, it’s important to err on the side of caution and choose pipes that are slightly larger than what you think you need. This will ensure that you have enough water pressure and avoid any problems down the road.
In conclusion, PEX pipe is a great option for your shower. It is durable, flexible, and easy to install. It comes in a variety of sizes, so you can choose the perfect one for your needs.
