What is a shower diverter valve that and more here?

How often do you shower or bathe? If you answered ‘once every day’, then you might want to read this article. The answer to this question has always fascinated me. I’ve never really understood why some people take showers every day and others don’t.

There are two types of shower diverters: automatic and manual. Automatic shower diverters are controlled by sensors that detect water pressure and automatically turn off the flow of hot water once the user steps out of the shower. Manual shower diverters are operated manually by turning the valve handle clockwise until the water stops flowing.

What is a shower diverter valve?

A shower diverter valve (SDV) is an appliance used in plumbing systems to control the flow of water from one fixture to another. It’s also called a “diverter” or a “shower diverter”. A shower diverter is usually installed between a bathtub faucet and a showerhead, but it can be installed anywhere where there is a need for controlling the flow of water.

Types of shower diverters

Shower diverters come in several different styles. Some are designed to work with a single-handle tub/shower combination, while others are designed to work with multiple-handles. There are even special-purpose diverters made just for use with certain kinds of fixtures like handheld showers or showerheads.

Single-handle diverters

These diverters are typically installed on tubs and showers with only one faucet head. They’re available in three basic configurations:

• Single-handle diverters allow the flow of water through both handles simultaneously. This means that the user can choose which handle he or she wants to use at any given time.

• Single-handle bypass diverters allow the flow to go directly into the drain when either handle is turned on.

• Single handle diverters allow the flow through one handle at a time. When the first handle is turned on, the second handle turns off.

Multiple-handle diverters

In addition to being able to control the flow of hot water through a single handle, these diverters can also be set up to operate with two or more handles. Multiple-handle diverters are generally more expensive than single-handle ones because they require more parts. However, they offer greater flexibility. For example, if your bathroom already has two separate controls for the shower and the tub, you may not have to buy anything new.

Special-purpose diverters

These diverters are specifically designed to work with certain kinds of fixtures. For example, handheld showers and handheld sprayers have their own unique diverters. Handheld showers are very popular now, so most manufacturers make special-purpose diverters for them.

How do shower diverters work?

The principle behind all shower diverters is simple: when the water reaches a certain temperature, it will begin to expand. As it expands, it pushes against the walls of the pipes that carry it. Eventually, the force exerted by the expanding water becomes too much for the pipe wall, causing it to crack and leak. By installing a shower diverter, you can prevent this from happening.

The way a typical shower diverter works depends on its type.

Automatic shower diverters

An automatic diverter automatically detects when the water is getting close to reaching a dangerous level and shuts itself off. The best known kind of automatic diverter is the thermostatic switch. These switches are designed to shut themselves off when the water gets too hot. You’ll find them mounted inside the wall near the faucets on many older homes.

Handheld shower diverters

A handheld shower diverter uses a thermistor to detect the temperature of the water. If the water gets too hot, the thermistor heats up until it reaches a safe operating point. At this point, the thermistor sends out an electrical signal that closes a circuit. This causes a valve to open, allowing the water to escape.

Spray Head diverters

A spray head diverter operates similarly to a handheld shower diverter. It’s basically a handheld shower diverter that’s been modified to fit over a standard spray head instead of a handhold. Most sprayheads come equipped with a built-in diverter.

Shower diverter installation

Installing a shower diverter is fairly straightforward. First, remove the old diverter. Then, install the new one in place. Finally, connect the supply line to the diverter and turn on the water.

There are several different ways to mount a shower diverter. One common method involves placing the diverter between the wall and the fixture. Another option is to use a bracket that mounts directly to the wall. Some people prefer to put the diverter in the center of the shower wall. Whichever mounting method you choose, make sure that the diverter is securely fastened to the wall. Otherwise, it could fall off during normal use.

If you’re using a handheld shower diverter, you should always test it before turning on the water. Doing so will help ensure that it functions properly. Also, make sure that the thermistor is correctly installed. If it isn’t, the diverter won’t function as expected.

Common shower diverter problems

Most shower diverters are relatively trouble free. However, there are some potential issues that may arise.

Thermistor failure

One of the biggest concerns about shower diverters is the possibility of a faulty thermistor. Thermistors are used to measure the temperature of the water in order to determine whether or not the diverter should be activated. If the thermistor fails, the diverter will continue to operate even though the water has gotten dangerously hot.

In most cases, a malfunctioning thermistor doesn’t cause any serious damage. But if left unchecked, it could eventually lead to leaks, mold growth, and other costly plumbing problems. To avoid these problems, check your thermistors regularly. Replace them if they fail.


Leaks can occur for a number of reasons. A leaky diverter could allow hot water to flow into the bathroom. Or, it could allow cold water to enter the bathroom. Either way, it’s important to fix the problem immediately.

Leaks can also develop when the diverter is improperly mounted. Make sure that the diverter fits snugly against the wall. If it doesn’t, it might move around slightly during use. This could result in leakage.


Shower diverters are easy to install. They offer a convenient alternative to traditional handheld showers. And, they provide a more comfortable experience than traditional handheld showers. In addition, they can save money by reducing energy consumption. So, if you’re looking for an affordable solution to a common bathroom issue, consider installing a shower diverter.
