How to Choose the right PEX diameters for shower?

If you’re in the market for a new shower system, you might want to consider using PEX instead of copper for your water supply line. PEX, or Cross-linked polyethylene, has become a popular choice due to its flexibility, durability, and affordability. In fact, PEX has largely replaced copper-made pipelines in modern homes.

To install PEX for your shower, you’ll need to choose the right size based on your water flow and pressure requirements, the inner diameter of your shower for the supply line, and your home’s design. In this article, we’ll discuss these important factors and provide you with different PEX shower plumbing diagrams to help you with a quick and easy DIY installation of the system. By the end of this article, you’ll have the knowledge you need to confidently choose from ½-inch, 3/8-inch, ¾-inch, and 1-inch PEX diameters for shower.

Why PEX Pipes are Popular?

PEX pipes have become a popular choice for residential use due to their affordability and flexibility. Unlike copper pipes, PEX pipes are cheaper and easier to install, making them an excellent option for DIY projects. PEX pipes are also highly durable and resistant to leaks and damages when used in combination with a manifold system for showers.

PEX pipes are made of cross-linked polyethylene, which makes them highly flexible and easy to bend around corners and obstacles. They come in different sizes to meet various needs, making it easy to find the right size for your shower. PEX pipes are also compatible with a range of heating systems, making them a versatile choice for homeowners.

In summary, PEX pipes are popular because they are affordable, flexible, durable, and easy to install. They are an excellent alternative to copper pipes and are rapidly gaining popularity among homeowners.

What Size PEX for Shower is Ideal?

When it comes to choosing the ideal PEX size for your shower, there are a few things you need to take into consideration. These include the PEX diameter, water pressure requirement, manifold system, and pressure drop. Let’s take a closer look at each of these factors.

PEX diameter:

The nominal sizing of the PEX is an important factor to consider when selecting the appropriate PEX for your shower system. The inner diameter of the PEX tubing will determine its compatibility with different fixtures and fittings.

PEX tubing comes in a range of sizes, from 3/8-inch to 1-inch. For shower systems, the ¾-inch inner diameter is typically used. As such, both ½-inch and ¾-inch diameter PEXs will be compatible with the shower fixtures in your bathroom. Additionally, ½-inch to ¾-inch diameter PEX is suitable for residential use with adequate water flow.

Water pressure requirement:

The required water pressure is another important factor to consider when selecting the appropriate PEX for your shower. Homeowners are increasingly looking for plumbing systems that reduce water wastage. As such, a narrower PEX pipeline may be installed to slow down the water flow rate and reduce water wastage for the shower fixture.

For example, a ½-inch PEX may be installed for the ¾-inch shower fixture. However, this will increase bathing time as it reduces the water flow rate. If you are not concerned with waiting a little longer under the shower, you may opt for a 3/8-inch PEX diameter to conserve water.

Manifold system:

The manifold system of your household and shower fixtures is another factor to consider when selecting the appropriate PEX for your shower. You should choose a PEX diameter that is compatible with the manifold system of your shower.

With the flexibility and continuity of PEX, it can be used with various manifold systems in your household. However, you should choose a narrower water supply pipeline than the diameter of the standard manifold system of your shower fixture. As most whole-house manifold systems, including the shower fixture, feature ¾-inch valves, you can easily choose from the following three PEX diameters: ¾-inch, ½-inch, and 3/8-inch.

Consider pressure drop:

The distance between the shower fixture and the manifold system of your home is another factor to consider when selecting the appropriate PEX for your shower. The longer the distance, the wider your PEX pipeline should be for proper water pressure.

For instance, a ½-inch PEX pipeline delivers adequate water pressure for a 350-ft distance. If the distance is 250ft, you can choose 3/8-inch PEX diameters. It is important to choose the appropriate size PEX that won’t drop the water pressure and cause inconvenience.

In conclusion, selecting the appropriate size PEX for your shower system requires careful consideration of the PEX diameter, water pressure requirement, manifold system, and pressure drop. By taking these factors into account, you can ensure that your shower system functions optimally.

PEX Shower Plumbing Diagram

Installing a PEX pipeline for your shower fixtures is a flexible and easy DIY project. However, you will need a plumbing diagram for proper installation. Luckily, there are many PEX plumbing diagrams available online. You can also consult a professional plumber to get a suitable diagram. Ensure that the diagram includes the appropriate valves, fittings, and connectors for the PEX plumbing system. Remember to connect the hot and cold water lines to the water meter and showerhead respectively.

Frequently Asked Questions:

When it comes to running PEX to your shower, you may be wondering what size to use. A 3/4-inch PEX is suitable for your shower manifold system without affecting water flow or pressure. As for the water line size, a 1/2-inch line is ideal for your shower fixture. However, you can upsize it to 3/4-inch with PEX due to its flexibility and easy installation process.

Final Words

Now that you know the correct PEX diameters for shower, you can confidently install them. Both ½-inch and ¾-inch PEX diameters are suitable for providing sufficient water without any decrease in pressure or flow.

PEX is a flexible and affordable option, making it a great choice for shower fixtures. By selecting the right size, you can ensure that your PEX pipeline is properly mounted and ready for your bathing needs.
