To install a concealed shower mixer, you will first need to locate the wall studs and mark the desired placement for the mixer. Next, cut an opening in the wall to accommodate the mixer valve. Connect the hot and cold water supply lines to the mixer valve, ensuring they are properly sealed with plumber's tape. Finally, attach the trim plate and handle to the mixer valve and test the water flow to ensure everything is working correctly. It is recommended to consult a professional plumber if you are unsure about any step in the installation process. **

To adjust the mixer tap in the shower, first, turn on the water to the desired temperature. Then, locate the handle or knob on the mixer tap that controls the temperature. Turn the handle or knob to the left for hotter water and to the right for colder water. Adjust the handle or knob until you reach the desired temperature. If the water pressure needs to be adjusted, there may be a separate handle or knob for that purpose. **

The two taps of the shower mixer are likely dripping because the washers inside the taps have worn out over time. When the washers wear out, they are no longer able to create a watertight seal, causing water to leak out. This is a common issue in older faucets and can usually be fixed by replacing the worn-out washers. If the problem persists after replacing the washers, it may be a sign of a more serious issue with the internal components of the mixer that may require professional repair or replacement. **

To replace the shower faucet, mixer tap, and thermostat in the shower, you will first need to turn off the water supply to the shower. Next, remove the handle and trim plate of the faucet to access the cartridge or valve.

Finally, reassemble the handle and trim plate, turn the water supply back on, and test the new fixtures for proper functioning. **

To remove the handle of a single lever shower mixer, you will first need to locate the set screw that holds the handle in place. This is usually located on the underside of the handle or behind a decorative cap. Use an Allen wrench or screwdriver to loosen and remove the set screw. Once the set screw is removed, you can then pull the handle off the mixer valve. Be sure to turn off the water supply to the shower before attempting to remove the handle to avoid any water leakage. **

For replacing a shower thermostat mixer, a waterproof silicone sealant is typically needed. This type of sealant is designed to create a watertight seal and prevent leaks around the edges of the mixer. It is important to use a high-quality silicone sealant that is specifically formulated for use in wet areas such as showers to ensure a long-lasting and effective seal. Additionally, it is important to follow the manufacturer's instructions for applying the sealant to ensure proper installation and functionality of the new shower thermostat mixer. **

To prevent water from splashing uncontrollably from the shower mixer tap, one can adjust the water flow to a lower pressure. This can be done by turning the tap to a lower setting or adjusting the flow control on the showerhead. Additionally, using a shower curtain or screen can help contain the water within the shower area. Regularly cleaning the showerhead to remove any blockages can also help maintain a steady flow of water and prevent splashing. **
