How To Change Temperature Control On Your Shower

Showering should be a relaxing experience, but a faulty temperature control can quickly turn it into a frustrating ordeal. Whether your shower is too hot, too cold, or simply inconsistent, understanding how to adjust or replace your temperature control is crucial for a comfortable bathing experience. This guide will walk you through the process, covering various shower types and providing helpful tips along the way.

Identifying Your Shower's Temperature Control

Before diving into the repair or replacement process, you need to identify the type of temperature control your shower uses. Common types include:

• Single-Handle Mixing Valves: These valves typically have a single handle that controls both hot and cold water flow simultaneously. Rotating the handle changes the water temperature. These are becoming increasingly common in modern homes.

• Two-Handle Mixing Valves: These valves feature separate handles for hot and cold water. Adjusting each handle independently allows for precise temperature control. These are more traditional but still widely used.

• Thermostatic Mixing Valves (TMVs): TMVs maintain a consistent water temperature despite fluctuations in water pressure. They are usually more complex and require more specialized knowledge for repair or replacement.

Important Note: Before starting any work, always turn off the water supply to the shower. This usually involves shutting off the valves located behind the shower or near the water heater. Failure to do this could lead to water damage and injury.

Adjusting Existing Temperature Controls

Single-Handle Mixing Valves

Minor temperature adjustments on single-handle valves are usually straightforward. Simply turn the handle to adjust the water temperature. If the temperature is consistently wrong, the problem might lie within the valve itself and may require replacement (detailed below).

Two-Handle Mixing Valves

Two-handle valves offer more precise control. If the water is too hot or too cold, simply adjust the respective handle. If the handles are loose or difficult to turn, you might need to tighten the handle screws or replace worn-out washers (this is a relatively easy DIY repair but may require specific replacement parts for your shower model).

Replacing a Shower Temperature Control Valve

Replacing a shower valve is a more advanced DIY project. It's recommended to have some plumbing experience before attempting this task. If you're unsure, it's always best to hire a qualified plumber.

Tools and Materials You May Need:

• Adjustable wrenches: For disconnecting and connecting water pipes.
• Screwdrivers: To remove the shower handle and trim plate.
• Pliers: For gripping and twisting.
• Teflon tape: To seal pipe threads and prevent leaks.
• New shower valve: This must match your existing valve type and plumbing configuration. It’s crucial to check your shower model to ensure correct replacement.
• Bucket or towels: To catch any spilled water.
• Safety Glasses: Protect your eyes from debris and water spray.

Step-by-Step Guide (General Steps - specifics vary greatly depending on valve type and model):

1. Turn off the water supply. This is the most crucial step to prevent flooding.

2. Remove the shower handle and trim plate. This usually involves removing screws or carefully prying them off.

3. Disconnect the water supply lines. Carefully disconnect the hot and cold water supply lines from the old valve. Have a bucket or towels ready to absorb any residual water.

4. Remove the old valve. This often requires loosening various nuts and connections.

5. Install the new valve. Ensure it's correctly aligned and securely fastened.

6. Reconnect the water supply lines. Wrap the threads with Teflon tape to ensure a leak-proof seal.

7. Reinstall the trim plate and handle.

8. Turn on the water supply. Check for any leaks.

When to Call a Professional

If you're uncomfortable working with plumbing, or if the problem seems beyond a simple adjustment, it's always best to call a qualified plumber. Complex issues with thermostatic mixing valves, for example, should generally be left to professionals.

By following these steps and understanding your shower's temperature control system, you can ensure a comfortable and enjoyable shower experience. Remember safety is paramount; always turn off the water supply before starting any repairs.
