Buying Guide on the Best Shower Valves for PEX Plumbing

Shower Valve for Pex

A PEX valve is used to connect two pieces of PEX tubing together. There are many different PEX valves available today, so it is vital to consider which one to purchase.

Types of Valve:

Two types of water transfer valves can be used with PEX piping, including pressure balancing valves and thermostatic valves. Each type of valve has its own unique features.

Pressure Balancing Valve:

Pressure-balancing or PB valves are common in plumbing and regulate hot and cold water pressure. They work by using a set of pistons and diaphragms that detect changes in water pressure. Maintaining a steady water temperature is their function.

PB valves have a single-handle shower faucet that controls water pressure and temperature by turning left and right. They help to conserve water by preventing pressure imbalances that can lead to wasted water.

Thermostatic Valve:

Thermostatic shower valves (TSV) provide more precise control over the water temperature. A thermostatic mixing valve for the shower comprises two handles: one for controlling the flow of water and the other for setting the desired temperature.

The mixing valve for the shower is connected to a sensor that monitors the water temperature and automatically adjusts the flow of cold or hot water as needed to maintain the set temperature.

Showering with a thermostatic valve can be a more comfortable experience, as you no longer have to worry about sudden changes in water temperature. TS valves can help to save energy by preventing wastage from excessively hot or cold water.

Type of Connection:

When Should a Shower Valve be Replaced

There are two main types of connections – compression and barbed. Compression connections are more common and easier to use but require special installation tools. Barbed connections are less common, but they offer a more secure connection.

Compression Connections:

Compression connections are made by crimping a sleeve onto the end of a pipe. The sleeve is placed over the fitting, and the two are forced together. While this connection is quick and easy, replacing it can be difficult. Compression connections can damage if not installed correctly.

Barbed Connections:

Barbed connections are made by inserting a small barb into the end of the pipe. Afterward, the barb is inserted into the fitting and secured. 

This type of connection is more secure than a compression connection but can be more difficult to install. Uninstalled barbed connections can damage the device.


Pex shower valves come in two main varieties: plastic and metal.

Plastic valves are generally less expensive than their metal counterparts but are also more likely to break under high temperatures or heavy use. Conversely, metal shower valves are more expensive but durable and less likely to break.

A plastic shower valve may be a good option if you are on a tight budget or only plan to use your shower occasionally. A metal shower valve may be a better choice if you have more to spend and plan to use your shower regularly.

How do I Know What PEX Valve Size I Need for My Shower?

How Do You Install a PEX Shower Valve

If you’re only installing a new single or double shower-head instead of an existing shower head, then a 1/2″ valve will be sufficient. For multiple shower heads or other fixtures, you’ll need a 3/4″ valve.

Remember that 3/4″ shower valves are more expensive than 1/2″ valves, so you must factor that into your decision. If you use a different diameter valve or supply line, you can convert between sizes using an adapter.

What size PEX should you run to your residential shower?

For most residential applications, PEX tubes have diameters ranging from 3/8-inch to 1-inch. If you’re installing PEX for the first time or replacing old water lines, using 1/2-inch or 3/4-inch tubing for your main lines is a good idea.

These sizes will provide adequate flow for most homes. Of course, there may be some situations where a smaller diameter tube is needed. For example, if you’re connecting PEX to an existing fixture with small inlet ports, you may need to use a 3/8-inch tube.

Does the PEX shower valve reduce water pressure?

How to Install Moen Shower Valve with Pex

The size of the piping plays a role in water pressure. A 1/2″ pipe will have less pressure than a 3/4″ pipe. So, if you hope to increase water pressure, a larger pipe size may be your most effective option.

Another factor to consider is the shower valves themselves. When using a shower valve designed for high water flow, you may lose some pressure when you reduce the pipe size.

How do you install a PEX shower valve?

Installing a PEX shower valve is a relatively easy process that can be completed in just a few minutes. Here is the process:

Step 01: Remove the existing shower valve by loosening the retaining nuts that secure it to the wall.

Step 02: Use a hacksaw to cut through the copper pipes that supply water to the valve.

Step 03: Remove the old shower valve and any remaining debris from the wall.

Step 04: Apply a thin layer of plumber’s putty around the base of the new valve.

Step 05: Thread the supply lines onto the inlet ports of the shower valve and tighten them securely.

Step 06: Use a wrench to tighten the keeping nuts that secure the shower valve to the wall.

Step 07: Turn on the water supply and test the shower to ensure it works properly.

How long should PEX shower valves last?

Can I Use PEX for Shower Valves

The most common shower valve typically requires replacement every 4-5 years. With proper maintenance, they can last even longer. For example, regularly flush the valve with vinegar to remove built-up deposits. 

Check the seals and gaskets periodically to ensure they are still in good condition. By taking these steps, you can extend the life of your shower valve and enjoy years of trouble-free performance.

Now you know everything from choosing the proper shower valve for PEX to installing it properly. Read our review of the top PEX shower valves carefully and make the right choice for your home. With our additional information, you can confidently tackle the project.

Make Your Investment Count: Choose the Proper Shower Valve for PEX!

Installing the suitable shower valve for your PEX plumbing is a smart investment in the health and longevity of your plumbing system and the overall value of your home renovations.
