Tuscany Shower Valve Adjustment

Before we delve into the adjustment process, it’s important to understand the basic components of a Tuscany shower valve. Typically, a Tuscany shower valve comprises three key elements: the handle, the temperature limiter, and the pressure balancing mechanism.

1. Handle:

The handle is the main control mechanism of the shower valve. It is responsible for controlling both the water flow and the temperature. The handle can be in the form of a lever, knob, or dial, depending on the specific model.

It allows you to adjust the temperature by turning it either clockwise or counterclockwise.

2. Temperature Limiter:

 The temperature limiter is an important safety feature of the Tuscany shower valve. It allows you to set a maximum temperature limit to prevent scalding accidents. 

The limiter is typically located behind the handle and can be adjusted to restrict the handle’s movement beyond a certain temperature threshold. 

This ensures that the water temperature doesn’t exceed the desired limit, providing added safety during showers.

3. Pressure Balancing Mechanism:

The Tuscany Brass shower valve also equips a pressure-balance spool inside to regulate the shower water pressure.

This mechanism works automatically to ensure that the water pressure remains consistent, even when there are fluctuations in the hot or cold water supply. 

How To Adjust The Temperature On A Tuscany Shower Valve [Step-by-step Guidelines]

It is easier to adjust the temperature on the Tuscany shower valve, no matter if you are a novice or experienced in plumbing work. Follow the step-by-step instructions below and ensure the proper temperature adjustment on your Tuscany shower valve:

Manage Necessary Tools:

Before you begin, here are the few tools you need to manage for the correct adjustment of your shower valve:

  • A flat-head screwdriver
  • Allen key
  • Standard pliers
  • Needle-nose pliers
  • Drop cloth

Step-by-step Instructions:

Step 1: Turn Off The Water Supply & Protect The Drain

Before attempting any adjustments, first off, turn off the water supply to your shower system. When done, take a drop cloth and lay it on the bottom of the shower to block off the drain. It is essential as it will prevent screws and other small parts from going down the drain while adjusting.

Step 2: Remove The Handle

Now at this stage, you will need to remove your shower handle to get access to the temperature mechanism. Hold on to the escutcheon plate and lose all the screws over there. Then use an Allen key and remove the set screws underneath of the handle.

When done, you can easily remove the handle from your shower system. Gradually, remove the loosened screws and take off the escutcheon plate itself. 

Step 2: Remove The Faucet Bushing Cap

After removing the handle and cover plate, turn the bushing cap covering the cartridge and remove it.

This component is responsible for setting the maximum temperature allowed by the valve. It is usually marked with temperature indicators or a rotational arrow to guide you. If required, you can slide off the cartridge to better adjust the valve. 

Step 4: Adjust The Temperature Limit

On the temperature limiter mechanism, you will find a red temperature limit stop in the middle that turns clockwise or counterclockwise to increase or decrease the maximum temperature setting.

Now pay attention to the markings or hot indicators to guide your adjustment. Refer to the manufacturer’s instructions for any specific guidance on the temperature range or limit for your particular Tuscany shower valve.

If your Tuscany shower valve is new, by default you will find the temperature limiter stop is set to the highest temperature setting (A). To reduce or adjust the temperature, slightly take off the device and turn it clockwise to the desired B or C setting. 

Step 5: Reassemble The Faucet Parts

Once you have made the necessary temperature adjustments, reconnect the nut on the cartridge. Then reassemble the cylinder and cover the plate back in place and secure it with the needed screws. Ensure a snug connection off all the parts.

Finally, reattach the handle to the handle adapter, ensuring it fits securely. Align the handle properly and insert the screw/set screw back into place. Tighten the screw/set screw by turning it clockwise until it is snug, being careful not to overtighten. 

Step 6: Check The Temperature Control

After making adjustments to the temperature control on your Tuscany shower valve, it’s crucial to observe the changes in water temperature and fine-tune them to reach your desired comfort level. Follow these detailed steps:

Step# 1: Start by turning on the shower and allowing the water to run for a few moments. This will help the water reach a stable temperature and ensure that any adjustments you make accurately reflect the actual temperature.

Step# 2: As the water flows, carefully observe the temperature changes. Pay attention to whether the water is too hot, too cold, or at your desired comfort level. Keep in mind that it may take a few moments for the water temperature to stabilize after each adjustment.

Step# 3: If the water is not at your desired temperature, make small adjustments to the temperature control on the Tuscany shower valve. Gradually turn the handle clockwise or counterclockwise, depending on the specific instructions for your valve, to fine-tune the temperature.

Step# 4: Continue making small adjustments until you achieve the desired temperature. Take note of the changes in water temperature after each adjustment and assess whether it meets your preferences. Be patient and make incremental changes to avoid sudden and extreme temperature fluctuations.

Step# 6: Once you have reached your preferred temperature, leave the temperature control in that position. This ensures that subsequent showers will start at the desired temperature without the need for further adjustments.

Step # 7: Consult The User manual Or Contact Customer Support. If Needed Keep in mind that Tuscany shower valves may have slight variations in design and functionality depending on the model and manufacturer. 

If you encounter difficulties or require further guidance, consult the user manual provided with your shower valve or contact the manufacturer’s customer support for assistance.

What Is The Safe Temperature For My Shower Water?

While making temperature adjustments, I bet there would be a lot of queries on your mind about what is the ideal temperature to shower in. 

To experience a comfortable and safe bath, it is best to keep the water temperature at an average of 98°F (37°C) to 101°F (38.3°C) and not more than 105 °F (41°C). This is the ideal temperature for your shower that will help you to avoid major risks to your skin health and many other discomforts to your body relating to excessive hot showers. 

Conversely,  if the water temperature is about 120°F, it can cause burns and scalding in a short period. Thus before stepping into the shower, it is always advisable to test the water with your hand or a reliable thermometer to avoid unexpected temperature changes. Even the step is more crucial if you have just adjusted the temperature on your shower valve. 

Why Is My Tuscany Shower Valve Not Working After Making Adjustments [Learn Easy Solutions]
