What To Do When Water Comes Out Of Tub But Not Shower

One common issue of connected tub and shower is: water not coming out of the shower or tub. And while it’s possible to face both simultaneously, the shower issue tends to happen the most as the tub remains on the lower level. But what exactly explains when water comes out of tub but not shower?

When the water is not coming from the shower, you are likely dealing with a diverter problem. This part of the fixture controls the water flow and directs the water from the tub to the shower and vice versa. And it can get stuck in position.

But that’s not the only reason why you may face this issue. There is another potential reason that you should know. And the good news is that this discussion sheds light on both and offers some easy fixes you can follow without professional help.

Potential Causes of the Problem

Before discussing the fixes, you need to understand the main reasons first. So, here’s a brief description of the two potential causes that can make the shower not get any water but the tub does –

1. Issue with the Diverter

If you take a closer look at the tub spout, you will notice a knob on the end. It’s called the shower diverter. As discussed earlier, the shower diverter directs the water to the shower head from the tub spout.

But as the diverter’s flapper ages, it may lose the ability to properly divert the water from one to another. That is generally when you don’t get water from either the tub or the shower.

In fact, issues with the shower diverter can also lead to other problems, such as dripping from the faucet handle and the spout.

2. Clogged Showerhead

It’s not just the diverter that can lead to this issue with the shower. It could also be due to mineral deposits. And if your water supply offers hard water, you might want to check on clogs before inspecting the diverter.

The thing is, hard water contains a lot of minerals. And as this mineral-rich water flows, it tends to make some sediment settle on the lines and the showerhead. Now, when there’s an excessive amount of it, the pipe or fixture fully clogs up.

Troubleshooting Shower Not Getting Water but Water Comes from Tub

You do not need to call a plumber to troubleshoot this issue. Instead, follow these simple steps to get the shower working like it’s brand-new –

1. Fixing the Clogged-up Showerhead

As mentioned earlier, you are likely dealing with a clogged showerhead if you have a hard water supply. And to clear out the nozzles of the showerhead, you will need to go through the following steps –

2. Shower Diverter Valve Troubleshooting

So, if it’s not a clogged showerhead, the diverter valve is certainly the root cause of the issue. Here are the steps you need to take to troubleshoot it –

Here, if you can not determine the size of the old diverter, look at the manual of the shower system. It should have information on all the parts. Based on that, purchase a replacement unit.

It’s possible to enhance the lifespan of shower diverters and lower the chances of the showerhead getting clogged. Take a look at these tips –

Final Words

Regarding the issue of water coming out of the tub but not the shower, it’s generally the diverter to blame. But a clogged showerhead can also be the culprit. No matter what it is, troubleshooting the problem should be a piece of cake for you now.

However, remember that you will need to follow a different set of troubleshooting steps if you have an electric shower.
