How to set the thermostat on a shower mixer tap? A few aspects worth knowing about this device

We all appreciate the comfort of a warm shower after a long day at work. But what can you do when the water suddenly becomes too hot or too cold? The problem may lie with the thermostat in your shower mixer. In this article, we explain what a thermostat is, how it works, and how to repair or replace it when it stops working properly. Read on!

What is a thermostat in a shower mixer?

The thermostat in a shower mixer is a highly practical and technologically advanced device that ensures a constant and safe water temperature while you shower. Its main task is to control the temperature of the outgoing water, regardless of changes in pressure in the plumbing system. This means that even if someone turns on a tap in another room or flushes the toilet, the water temperature in the shower remains unchanged.

Shower thermostats are fitted with special mechanisms that automatically mix hot and cold water in the correct proportions. Modern models may also include additional features, such as safety locks that prevent accidentally setting the temperature too high. These are well worth considering, especially in homes with young children.

Thanks to a thermostat, when using the shower you can enjoy not only convenience but also savings on water and energy. A constant temperature eliminates the need to adjust the water flow during every shower, which translates into lower water consumption and less energy needed to heat it. Thermostatic shower sets are available in various shapes and styles, allowing them to be easily matched to your bathroom decor, making it not only more functional but also more attractive.

How does a thermostat in a shower mixer work?

The thermostat in a shower mixer works on the principle of mixing water from two sources — cold and hot — to achieve a set temperature. When you set the desired temperature on the thermostat knob, the internal mechanism adjusts the flow of both water streams to reach and maintain that temperature. Moreover, modern thermostats are equipped with special valves that automatically react to changes in water pressure or temperature, further increasing comfort and user safety.

A faulty thermostat in a shower mixer: how to deal with it?

Sometimes the thermostat may stop working correctly. Sudden changes in water temperature or the inability to adjust it should raise concern. In such a situation there are two main solutions: repair or replacement of the device.

How to repair a thermostat in a shower mixer?

Repairing the thermostat can be relatively straightforward if you know the basics of plumbing. Follow these steps:

1. Turn off the water: before you start, make sure you shut off the water supply to the shower to avoid flooding the bathroom.
2. Remove the knob: carefully take off the temperature control knob. It is usually secured with a screw, which you will need to unscrew.
3. Check the condition of the seals: inside the mixer there are seals that may be worn or damaged, causing the thermostat to malfunction. If you notice they are in poor condition, replace them with new ones.
4. Clean the mechanism: remove any limescale or debris that may be blocking the thermostat mechanism.
5. Check the thermostatic element: if the seals and mechanism are in good condition, the problem may lie in the thermostatic element itself. Check whether it works properly — it should expand and contract with changes in temperature. If it is damaged, it may need to be replaced.
6. Reassemble everything: if all is well, reassemble the mixer and check whether the problem has been resolved.

How to replace the thermostat in a shower mixer?

If the above method did not produce the expected result, the thermostat may need to be replaced. Here’s how to do it:

1. Buy a new thermostat: make sure the new thermostat is compatible with your shower mixer.
2. Turn off the water: as before, shut off the water supply.
3. Remove the old thermostat: take off the knob, undo the fixings and remove the old thermostat.
4. Install the new thermostat: fit the new thermostat, following the manufacturer’s instructions.
5. Check operation: once everything is reassembled, turn the water back on and check that the new thermostat is working correctly.

Thermostat: convenience in every home

Setting the thermostat in a shower mixer is the key to comfortable and safe showering. It is an advanced device that provides a constant water temperature, regardless of changes in system pressure. Thanks to it, you will avoid unpleasant surprises while showering. Keep it in good working order, and your evening wash will be pure pleasure — literally and figuratively!
