Can I Use PEX For a Showerhead? (Solved!)

Until recently, plumbing remodeling was never an easy task for average homeowners. Traditional galvanized pipes are heavy, and cutting new threads on these pipes was another daunting task on its own.

Later lighter and easy-to-cut copper pipes were introduced; however, the need to sweat the copper joints with a torch was intimidating and discouraged the use of copper pipes. But the introduction of plastic PEX pipes and connectors that are easy to attach to the PEX tubing has made bathroom plumbing remodeling accessible to most plumbing-averse homeowners.

However, many do-it-yourself homeowners have questioned the use of PEX for showerheads. This article attempts to clarify the misconception behind PEX and its use in the bathroom setting.

Cross-linked polyethylene (PEX) is a new and trendy type of flexible plastic pipe, perfect for showerheads. It is the function of the I.D. of the PEX tubing to adequately restrict the water so that it will fill the riser to the showerhead and drip out. PEX pipes are more straightforward to work with and suitable for showerheads.  

PEX For The Shower Head

What is a PEX pipe?

Cross-linked polyethylene (PEX) is a new standard of flexible plastic water pipe that is gradually replacing traditional galvanized steel, and copper has the most preferred water supply lines in both new construction and remodeling plumbing projects.

PEX quickly became most homeowners’ water supply lines’ favorite due to its price, performance, and flexibility. PEX pipes are a product of polymer molecules in polyethylene. This makes them unique, flexible, and durable.

What are the different types of PEX?

PEX-A Pipes

PEX-A is considered the superior type of PEX because it is the most malleable. PEX-A pipes are expensive and extremely flexible because they are assembled with peroxide.

Crosslinking takes place during the manufacturing process when the polyethylene is at the melting point. Most professional building contractors will recommend PEX-A because it can withstand the effects of freezing temperatures throughout the winter season.  

PEX-B Pipes

PEX-B is less superior to PEX-A; hence it’s categorized as “B.” PEX-B piping is less flexible than PEX-A, but they are designed to withstand deterioration as a result of minerals like chlorine.

Therefore, PEX-B pipings are the best option for homes in suburbs and cities that get a large supply of chlorine in their water. PEX-B pipes are more popular because more plumbing renovations happen in the suburbs and cities, and they cost less than PEX-A.   

PEX-C Pipes

PEX-C pipes are the least flexible and the least expensive, and PEX-C tubing are suspensible to holes and crack during the winter season.

They are designed for ordinarily utilized for small maintenance projects in buildings in areas with moderate climates. If you stay in the far north and experience below-freezing temperatures in the winter, don’t invest in PEX-C pipes; instead, go for PEX-A or PEX-B.

PEX pipes are superior and easier to use and maintain than copper pipes. PEX pipes are much more frost resistant, immune to corrosion and mineral build-up, and are not affected by electrolysis that may cause hole leaks in the copper pipeline.

PEX pipe is more resistant to bursting during winter than metal piping. In addition, the prices of PEX showerheads are cheaper, durable and they necessarily don’t require the services of professionals to install them, making them the favorite option for most enthusiastic DIYers and industry standards.  

Can I use PEX pipe for hot and cold water?

PEX plumbing pipes are flexible and can contrast or expand to withstand cold and mild hot water. However, the PEX water lines should not be connected to the house water heater.

The temperature of the supply from the water heater ranges between 120 to 150 degrees Fahrenheit, and PEX pipes are not designed to withstand this type of heat. In addition, there are blue and red color coding to distinguish between cold and hot water pipes.  

How to connect PEX pipe to shower?

PEX pipes are easy to connect to the shower; however, it is important to make sure the connections are watertight during fitting. Some of the common methods of ensuring watertight connection include

  • Expansion connection
  • Compression fitting
  • Push-fit connections

What PEX size is good for a shower?

There is actually no limit to what size to use, but 1/2-inch main lines are usually sufficient to get the water flowing into the showerhead. The standard plumbing rule is to simply replace the old water supply lines using PEX that is the same size.

PEX plastic pipes have a much superior flow rate than copper. But PEX fitting I.D. is smaller than the other pipes of similar size. Therefore, it actually reduces water pressure, but it does at an insignificant rate, so it’s nothing to be worried about.
