How to Fix a Leaky Shower Mixing Valve: A Step-by-Step Guide

Most shower rooms use mixing valves, which allow for the use of both hot and cold water, and enable the adjustment of water temperature. However, if you notice a leak from the mixing valve during use, here's how to handle the repair.

How to Repair a Leaking Shower Mixing Valve

First, turn off the valve of the water heater and the inlet to completely drain the water from the pipes. Next, locate the screw holes behind the mixing valve and remove the screws to detach the handle. If the internal sealing ring has aged, simply replace it with a new one of the same model. If the mixing valve itself is aged or corroded, you will need to replace it with a new valve.

Installation Tips for Mixing Valves

1. When installing a thermostatic mixing valve, check the positioning of the hot and cold water pipes beforehand. Generally, cold water is on the right side and hot water on the left side. Make sure not to connect them incorrectly as it will affect usability. If using solar or gas water heaters, do not install a thermostatic mixing valve, as they have lower water pressure, and ensure to install a filter.

2. For kitchen mixing valve installation, since this area is used frequently, it is essential to install it securely. Over time, it can easily become loose, so during installation, it’s advisable to tighten the valve. Using a larger screw nut can help secure it better.

3. When installing a mixing valve for a wash basin, most people use a dedicated angle valve. However, when installing, there may be a distance between the angle valve and the mixing valve. A long pipe connection can be used, and ensure that the hot and cold water pipes are secured properly.

4. For shower room mixing valves, improper installation can lead to significant inconvenience when in use. These mixing valves are typically installed within the wall. Thus, it's crucial to consider the thickness of the wall before installation. If the wall is too thin, the valve core cannot be properly embedded, so be particularly careful in this aspect.
