Tub Shower Diverter Not Working? Here's What To Do

24 Jun 2024

Few things are more frustrating than stepping into the shower, turning on the water, and finding it's going down the tub spout instead of the showerhead. That, my friend, is the telltale sign of a tub shower diverter valve that's decided to take a vacation. But don't worry, before you resign yourself to a life of lukewarm baths, let's explore why this happens and, more importantly, how to fix it.

The diverter valve might seem like a small, insignificant part of your bathroom setup, but it plays a crucial role in controlling the flow of water. Think of it as a traffic cop directing water either to the showerhead for a refreshing rinse or down to the tub spout for a relaxing soak. When working correctly, the diverter valve ensures a seamless transition between these two water destinations.

While the concept of diverting water flow has existed for ages, the modern tub shower diverter valve we know and occasionally curse came into being alongside indoor plumbing. As homes transitioned from communal baths to private bathrooms with both tubs and showers, the need for a mechanism to control water flow became apparent. Thus, the diverter valve was born, evolving over time from simple plugs and levers to more sophisticated valves we see in contemporary bathrooms.

But like any hardworking component, diverter valves can encounter hiccups. Mineral buildup from hard water, worn-out seals, and even loose connections can all lead to a diverter valve that's not pulling its weight. The result? A shower that refuses to cooperate or a trickle of water where you expect a steady stream. The good news is that many diverter valve issues can be resolved with a bit of troubleshooting and some basic DIY skills.

Before you call in a plumber, it's worth taking a closer look at your diverter valve and understanding the common culprits behind its malfunction. Is it a simple matter of mineral buildup that can be cleared with vinegar, or is it a more involved issue requiring a valve replacement? We'll dive into these possibilities and equip you with the knowledge to conquer your diverter valve woes.
