Common Shower Valve Service Questions

The amount of time it takes you to replace your shower knob will depend on your skill level and whether your existing knob is difficult to remove. It should only take about 30 minutes to get the job done, although it may take you a little longer. All in all, it's a quick project that has tons of visual impact.

How long shower valves last depends on the type you have, how much use it gets, the hardness of your water, and whether the valve was installed correctly. Good-quality brass shower valves are sturdy and last around 20 years, while lower-quality plastic valves last 4 to 5 years. Since shower valves wear out over time, you can proactively replace yours after 15 years or whenever you update your showerhead.

Shower cartridges, especially older ones, have some replaceable parts, such as O-rings, springs, and seals. The manufacturers of ceramic disc cartridges sometimes have repair kits to replace the ceramic discs in the cartridge. However, other components, such as the wax element in a thermostatic cartridge or the housing in other types, cannot be repaired and must be replaced with a complete cartridge if a problem arises.

You cannot replace a shower valve without turning off the water. Always turn your water off before doing any kind of plumbing work—and this project is no exception. Turning off the water is a best practice for personal safety and to keep things in your home dry.

Shower mixing valves are usually located behind the shower handles. Accessing the mixing valve is difficult for a DIYer, so it’s best to call a pro if you think this could be the issue. A plumbing repair expert has the right tools and knowledge to easily access the valve, diagnose the issue, and recommend repairs if needed.
