Quite a few of our clients confuse between a shower valve and a shower faucet.

The shower valve is the hidden part of the shower control.

On the other hand, the shower faucet aka trim kit is the outside part with the handle.

However, the design of a shower handle/faucet often denotes the design of the shower valve.

The good news is that the types of shower faucet handles will clearly depict the type of value that is beneath them.

At the same time, don’t confuse a shower valve with a shutoff valve. The latter is the one that is used for controlling water in your bathroom.

Needless to say, delta shower faucets are available in different models and each one differs from the other in terms of features.

It goes without saying that the proper information about your delta shower faucet model number will make your work easier.

The 3 steps identification mentioned below will do the trick for you.

Step 1: Identify the main features of your delta faucet

What I actually mean by saying that you need to identify the main features of your delta faucet is knowing the handle’s shape & size along with the style of your faucet.

As we all know, the brand delta designs each model separately so proper information about the aforementioned models really becomes important for you in all respect.

If we differentiate the delta faucets on the basis of handles, then they fall into three categories, that is, lever handles, single-round handles, and double-handle shower faucets.

Also, it’s a good idea to have information about the type of finish.

In general, delta faucets can be categorized into two sections on basis of the type of finish, that is, chrome, and brushed metal.

If you wanna differentiate the faucet models on the basis of the type of material, then it can be either metal or plastic.

Step 2: Remove the handle

  • Once you’re done with the aforementioned step, the next thing that needs to be done is removing the handle which can you do by using an Allen wrench.

What Type of Shower Valve Do I Have?

To find the answer to what type of shower valve I’ve, you need to look at various aspects of shower valves.

Moving further, I’ll walk you through various aspects in order to help you make an informed decision.

Shower Valve Manufacturer Identification

Frankly speaking, if you want to know how to identify the shower valve manufacturer, all you need to do is to check behind the shower handle at the center of the trim plate for the manufacturer’s symbol or brand name.

If you can’t locate any markings on the faucet then you don’t have an option but to start disassembling it.

You need to begin with the handle.

Moreover, you’ll be able to measure the cartridge (stem) length of the faucet or resort to the number of splines.

Needless to say, the information is vital in repairing or replacing the shower valve since some have specific measurements which may not fit into the others.

In layman’s terms, you identify the shower faucet brand by looking at the writing on the shower faucet.

Shower faucet types determine the shower valve underneath them.

Handle’s Number

You need to count the number of handles by having a look at the shower faucet.

  • In the absence of any handle, it will be a panel shower faucet that consists of buttons for controlling the water flow.
  • A single-handled faucet consists of one handle and controls the water pressure and temperature of the handle control.
  • A double-handled faucet consists of two handles that are used to control the hot and cold water flow.
  • A three-handled faucet consists of three handles. Out of the three handles, two are used for controlling the hot and cold water respectively. However, the third handle works as a diverter between the bathtub and the showerhead.

Out of the three types of faucets, the single-handled faucet is the one that is quite common and easy to use.

Again, I’m reiterating that shower handle types are very important in identifying the shower valve type.

Connection Type

You need to check above your faucet for the connection between the showerhead pipe and the rest of the plumbing.

Definitely, you’re gonna witness one of the below-mentioned things.

  • Handset/handheld showerhead – You can find this when a hose runs from the showerhead to the shower pipe behind the faucet handle.
  • Fixed/mounted showerhead: You’ll find this when the showerhead is directly mounted to the shower pipe from the wall.

Each of these has its own advantage. For example, if you’re looking for flexibility then a handheld showerhead is good to go.

On the other hand, a fixed showerhead may or may not be turned around through different angles.

Water Flow

You need to jot down the water behavior by turning on the showerhead and then moving through different shower settings.

In case, there is a single constant flow, then it simply means that the showerhead is a normal one.

On the other hand, if you find water bursts from the showerhead in a series of bursts, then expect your showerhead to be a massaging or pulsating one.

By closely watching both scenarios, you’ll be able to have a wholesome picture of the type of shower knobs and shower valves you’ve in your shower.

Furthermore, you can then get a replacement from the manufacturer with the right specifications.

Shower Valve Types Chart

Let’s have a quick look at shower valve types so that you can make an informed decision.

Shower ValveFeature
Shower mixing valveMixes hot and cold water from taps
Thermostatic valveControls water temperature and pressure
Shower transfer valveControls water flow to multiple outlets
Pressure balancing valveBalances hot and cold water pressure
Shower diverter valveDiverts water between the bathtub and showerhead

Shower Mixing Valve

Shower mixing valves are one of the old shower valve types and are meant to mix water from the hot and cold taps before delivering it to the showerhead.

Shower mixer valves are often found in old buildings and won’t regulate a sudden change in water pressure.

It is quite possible that this might scald you.

For example, the water pressure for cold water drops when someone turns on the water in a nearby tap or flushes the toilet.

Moreover, you can avoid this by keeping the hot water thermostat to a maximum of 120 degrees Fahrenheit.

Thermostatic Valve

Thermostatic shower valves control the temperature and pressure of the water coming out of the showerhead most importantly, a thermostatic valve comprise a thermostatic element that is capable of adjusting the flow of both hot and cold water in response to temperature changes.

Furthermore, you present the water temperature than the valve maintains it that way no matter the changes in the incoming hot and cold water.

On top of it, you can also set the volume of water from each water source (hot and cold) after which the valve does the rest.

A thermostatic valve is one of the most expensive shower valves given its features.

Shower Transfer Valve

It is a known fact that a transfer valve regulates water flow to multiple outlets such as bathtub spouts, handheld showerheads, and others at the same time.

Trust me, with transfer valves, you can use more than one outlet at the same time such as both fixed and handheld showerheads or showerheads with a tap.

Pressure Balancing Valve

As the name suggests, a pressure-balancing valve is capable of automatically balancing the water pressure from hot & cold pipes within 2-3 degrees Fahrenheit of the set temperature which further enhances the usability of the end users.

Needless to say, a pressure balancing valve is the most common and effective shower valve and is therefore popular by many other names such as anti-scald valves, or mechanical valves.

The valve has a unique style of working and expedites the process through a series of diaphragms or pistons which moves to balance the pressure of the water from the cold and hot water sources.

Moreover, they usually come with a single knob that changes the water temperature when turned to the left or the right.

Shower Diverter Valve

The last valve on our list is the shower diverter valve which works extremely well when it comes to diverting water from a bathtub faucet to the shower head.

By doing so, this valve helps in the installation of a bathtub and a shower in the same location, interesting, isn’t it?

Let’s have a quick look at some of the most popular and commonly used shower diverter valves that you can also opt for if they fall under your budget and caters to your requirements.

Tee Diverter

It consists of a pull arm that helps in running water in the tap, and as soon as the favorable temperature is achieved the arm is pulled in such a way that the faucet gets blocked, and as a result, the water is directed to the shower.

Two-Valve Diverter

As the name suggests, it uses a rotating control for hot and cold water.

The second control is used for diverting water between the tub and the shower.

Three-Valve Diverter

The unique thing about a three-valve diverter is that it uses three knobs, two are used for cold and hot water, and the third one helps in diverting water between the tub and shower.

In layman’s terms, knowing your shower valve type will help make the replacement and repair of the valves easier for you, and the process can be expedited in an epigrammatic span of time with ease.

I’m attaching a self-explanatory video for your perusal.

Step 2: Remove the Handle

Now, it’s time to remove the handle.

In order to expedite this step, you would be needing a screwdriver set such as Allen wrenches.

Moreover, the type of screwdriver that you would be needing will depend on the type of handle.

For example, if you’re working on a single-lever handle, you’ll have to locate a small set crew in the handle and use an Allen wrench.

On the other hand, if you’re working with a crystal handle, there will likely be a plastic cover that you can pop off with a flat-headed screwdriver.

Moreover, there you’ll be able to access the stem with a Philips screwdriver.

Last but not least, if you’re working with a faucet with two handles, you need to remove the decorative cap/plastic cover, that is, pry it off with a Philips screwdriver.

Step 3: Pull the Stem & Handle Out

After removing the screws, the next thing that needs to be done is to pull the stem and handle out as they often come out together.

Moreover, you may have to wiggle the stem as you gently pull it out to fully disengage it.

It is equally important to keep a note of the parts that are interchangeable.
