Can a Thermostatic Shower Valve Be Used with Cold Water Alone

The showerhead in the bathroom sometimes changes to cold water suddenly，which can be very inconvenient during bathing。As a result，more and more people are choosing thermostatic showerheads，which can better control water temperature without the need for manual adjustments。However，many people want to have the option to use only cold water without switching。Today，I'll teach you how to make a thermostatic showerhead provide cold water only。

一、How to Make a Thermostatic Showerhead Provide Cold Water Only

1、If you need to use cold water for an extended period，you can switch the pipes for hot and cold water。This way，you can use only cold water。When you want to switch back to hot water，just revert the water pipes。

2、Although thermostatic showerheads automatically adjust water temperature，they also have a rotary knob to control temperature。By adjusting the temperature setting for hot water and lowering it to the minimum，you can achieve cold water。

二、Differences Between Thermostatic Showerheads and Regular Showerheads

1、Thermostatic showerheads do not require manual temperature adjustments; they automatically balance hot and cold water pressure to achieve a suitable water temperature quickly。In contrast，regular showerheads require manual adjustments，and sometimes，excessive turning can suddenly change the water to cold，causing erratic temperature changes that may lead to catching a cold。

2、The valve core in regular showerheads is made of ceramic material，while thermostatic showerheads use a wax material for the valve core。

3、Thermostatic showerheads have an anti-scald function; if the temperature exceeds the set level，the water will automatically stop to prevent burns。Additionally，there is an anti-scald design in the faucet，so even if you accidentally touch it，you won’t get burned。Regular showerheads can deliver hot water directly，which can lead to burns，and touching the pipe can also result in burns because it gets very hot。

4、Thermostatic showerheads can save water effectively，as they provide water at a constant temperature without needing to run cold water to wait for hot water。Regular showerheads require back-and-forth adjustments，first letting cold water run until hot water comes out，which wastes water。

In summary，this is how to adjust the cold water setting on a thermostatic showerhead。While thermostatic showerheads automatically adjust water temperature，they do have some drawbacks，such as being more expensive than standard showerheads and cutting off water if the temperature is too high。We can choose a showerhead based on our specific needs。
