Description of Different Types of Diverters – Two Way and Three Way
In modern plumbing systems, diverters are important devices used to control the direction of water flow between two or more outlets. A diverter allows water to be redirected from one pipeline to another without stopping the water supply. These devices are commonly used in bathrooms, showers, and plumbing fixtures where water needs to flow to different outlets such as overhead showers, hand showers, or taps.
Diverters are usually installed along with faucets or mixing valves and are designed to operate easily by turning a lever, knob, or handle. The two most common types of diverters used in plumbing systems are the two-way diverter and the three-way diverter.
What is a Diverter?
A diverter is a valve-like plumbing device that changes the direction of water flow from one outlet to another. It allows the user to choose between different water outlets without installing separate pipelines for each fixture.
Diverters are commonly used in bathrooms where water may need to be directed to different outlets such as a bathtub spout, overhead shower, or hand shower.
Two-Way Diverter
A two-way diverter is a plumbing device used to direct water flow between two different outlets. It allows water to flow either to one outlet or the other, but not both at the same time.
This type of diverter is commonly used in simple plumbing installations where only two water outlets are required.
Working of Two-Way Diverter
The two-way diverter has an internal mechanism that redirects water flow when the handle or knob is turned. When the diverter is in one position, water flows to the first outlet. When the handle is moved to the other position, the flow is redirected to the second outlet.
Common Applications
- Bathroom shower systems
- Bathtub and shower combinations
- Kitchen plumbing systems
Advantages of Two-Way Diverter
- Simple design and easy operation
- Cost-effective plumbing solution
- Easy installation and maintenance
Three-Way Diverter
A three-way diverter is used when water needs to be directed to three different outlets. It provides greater flexibility and is commonly used in modern bathrooms with multiple shower options.
Unlike the two-way diverter, the three-way diverter allows water to flow to one outlet at a time or sometimes to two outlets simultaneously depending on the design.
Working of Three-Way Diverter
The three-way diverter contains a rotating internal mechanism that redirects water to different outlets depending on the position of the handle. The user can select the desired outlet by turning the control knob.
Common Applications
- Overhead shower systems
- Hand shower connections
- Bathtub and shower combinations
- Multi-outlet bathroom plumbing systems
Advantages of Three-Way Diverter
- Allows connection of multiple outlets
- Provides flexibility in water usage
- Suitable for modern bathroom designs
Materials Used for Diverters
Diverters are manufactured using durable materials to ensure long service life and resistance to corrosion.
- Brass: Most common material used for bathroom diverters.
- Stainless Steel: Used for high durability and corrosion resistance.
- Chrome-Plated Brass: Provides attractive appearance and protection from rust.
- Plastic or PVC: Used in lightweight plumbing systems.
The selection of material depends on the type of plumbing installation and water pressure conditions.
Installation of Diverters
Diverters are usually installed in the water supply line connected to bathroom fixtures. Proper installation ensures smooth operation and prevents leakage.
Basic Installation Steps
- Turn off the water supply before installation.
- Select a suitable location near the plumbing fixture.
- Connect the diverter to the main water supply pipe.
- Attach outlet pipes to the diverter ports.
- Tighten all connections securely.
- Turn on the water supply and test the diverter operation.
Correct installation ensures efficient water flow control and long-lasting performance.
Maintenance of Diverters
Regular maintenance of diverters helps prevent leakage and ensures smooth operation.
- Clean the diverter regularly to remove mineral deposits.
- Check seals and washers for wear.
- Replace damaged internal parts if necessary.
- Ensure proper tightening of pipe connections.
Proper maintenance extends the lifespan of diverters and improves plumbing performance.
Conclusion
Diverters are important plumbing devices used to control the direction of water flow in plumbing systems. The two main types are the two-way diverter and the three-way diverter. A two-way diverter directs water between two outlets, while a three-way diverter allows water flow to three different outlets.
These devices are widely used in bathroom and shower installations to provide flexibility and convenience. For ITI plumber trainees, understanding the working, types, and installation of diverters is essential for designing and maintaining efficient plumbing systems.
