Do You Need a Angle Valve for Your Shower Head

A showerhead is one of the essential bathroom items。Typically，after the renovation of a house，we need to install the showerhead。So，after installing the showerhead，is it necessary to install a shut-off valve (angle valve)？ Let's explore this question together。

一、Do you need a shut-off valve for the showerhead？

You can install a showerhead without a shut-off valve; you can simply tighten it directly by hand。This is because there is a rubber gasket at the connection point，which allows you to tighten it without much effort and ensures a watertight seal。Additionally，the pressure from the showerhead does not concentrate at the connection point，so there is no need for a specialized shut-off valve。

An angle valve is a type of shut-off valve，similar to a ball valve。Its structure and characteristics are derived from the ball valve，with the main difference being that the inlet and outlet of the angle valve are at a 90-degree angle。

二、What is the function of a shut-off valve？

1、A shut-off valve makes it more convenient for us to repair bathroom fixtures。It can block the flow of water，adjust water pressure，and control the pressure when it’s unstable or too high，preventing splashing in the toilet and avoiding damage or leaks from excessive pressure。

2、Usually，we need to install a shut-off valve at all water inlet points。The shut-off valve acts like a connector with a switch，connecting the outlet pipe to the inlet pipe。If there is cold and hot water，two shut-off valves will be required。The same principle applies to sinks。The size of the shut-off valve is generally small，and we usually install it on the wall where tiles have been affixed，making it easier to control the water flow。We should not overlook these small components，as problems can often arise from them。

In summary，as we can see from the above，a showerhead does not necessarily require the installation of a shut-off valve。However，having a shut-off valve is a useful accessory that facilitates the maintenance of bathroom fixtures。We should choose whether to install a shut-off valve based on our specific situation。I hope this helps everyone！
