Shower Diverter

Shower Diverter Not Working?

Taking a relaxing shower at night before retiring to bed or in the morning before you head to work should be as simple as the flip of a switch.

But showering is not easy when your shower diverter is not working. If water simultaneously pours from the tub faucet and showerhead, you might experience weak shower pressure or an inconsistent water flow. 

That’s why you need a home warranty coverage – to take care of these unexpected problems.

If you have no idea what a diverter is or what it does in your shower, this article will answer these questions and guide you on how to troubleshoot common shower diverter problems.

Let’s get started!

What’s a Shower Diverter?

Ever wondered what that mechanism that magically transfers water from your tub faucet to the showerhead is called? It’s called a shower diverter and has a few parts that work together to make it function properly. 

When your shower diverter valve is open, water can move freely through the faucet into the tub.

When it closes when you lift the knob, it causes pressure to build and directs the water upward and out of the showerhead.

There are three common types of shower diverter valves, and each has its own use: 

  • 3-valve diverter commonly found with 2-tap shower faucets (hot and cold)
  • 2-valve diverter, which can be used with a central faucet
  • tee diverter, which features a single valve, typically a knob on top of the tub faucet

When your shower diverter is in proper working condition, it cuts off water to either the showerhead or the faucet whenever you tell it to.

Shower diverters can stop working for various reasons, and when they do, they may cause leakages. Your shower diverter may need to be repaired or replaced.

If you think that your shower diverter valve has failed and happen to have a homeowner’s warranty, make a point to call your insurance provider and request them to send a qualified service technician to diagnose the problem for you.

By doing this, if the diverter valve failed from normal wear and tear, it can be repaired or replaced for a very small service fee.

Trouble Shooting Your Shower Diverter

The most reported issue shower diverters face is water coming out of both the showerhead and tub faucet. 

This might be because the inner rubber stopper does not create a good seal to completely block and reroute the water flow. But it could be another problem, like natural wear and tear. After continued use, your shower diverter can break down and need repair or replacement.

As soon as you’ve confirmed that it’s broken, the best thing is to repair the shower diverter in wall immediately. Some people postpone this simple task and end up creating a bad shower experience and costly water bills.

Troubleshooting a shower diverter is a DIY job that won’t take too much of your time.

Follow the nine actions listed below to troubleshoot and address the issue:

  • Shut Off the Water Supply

Do this before you do anything else. Do not turn off the faucet until the water stops flowing. 

It’s a lot easier to fix your diverter when you’re not worried about seeping water. 

  • Seal Off the Drain

Sealing off the drain with duct tape or something similar will keep small screws and other vital parts from not getting lost down the drainpipe.

  • Tighten the Screws Behind Your Shower Diverter

Your shower diverter may need very little work to be restored. 

Loose screws are the most common issue. Try to tighten them, and that might solve your problem all on its own.

If you tighten the screws behind the faceplate and the water continues to leak from the bathtub spout, proceed to the next step.

  • Look for Any Sediment Buildup

Inspect the area around the shower diverter and check if you’ll see any sediment buildup on any part. Dirt, limescale, and grease buildup can prevent water from flowing freely. 

If you find some clogging, soak the parts in vinegar for 50-60 minutes and then use a wire brush to scrub them down. Cleaning your diverter using vinegar is good for the environment because, unlike harsh bathroom cleaners, vinegar is organic and non-toxic.

Once free of debris, coat them with grease. While at it, scrutinize the stem washer for signs of wear and teas and exchange it if needed. 

  • Check the Pipe for Any Disconnected O-Rings and Washers

Disconnected washers and O-rings can affect your shower diverter’s functioning. 

If you come across any, get rid of them and replace them with new ones. 

Ensure you use the exact shapes and sizes before putting them in, then coat them using heat-proof faucet grease.

  • Disassemble the Shower Diverter

If your problem is still not solved, it may be time to do away with your old shower diverter. 

What you will need:

  • Adjustable wrench
  • Screwdrivers
  • Repair kit for your faucet model
  • Groove-joint pliers

Determine which of the three diverter types we listed is the one you have.

If your shower diverter has a gate-type valve, unbolt the threaded tub spout. If it has a rotating valve, loosen the nut found at its stem and get rid of the entire valve.

  • Replace the Diverter

Carry your old diverter to the plumbing supplies store to help you purchase the appropriate replacement.

Don’t worry; it won’t cost an arm and a leg, and it’s much easier than replacing individual parts.

  • Install the New Diverter

Installing your replacement unit should only take a few screws and some finagling. Just work backward from how you dissembled them.

Use a wrench or pliers to tighten up the diverter, but be careful not to overtighten it. 

Ensure that the parts don’t cross-thread each other. To guarantee that it’s in the proper position, adjust the stopper or twist the gate.

  • Turn Your Water Supply Back On

It’s time to test your new valve. 

Turn the water back on and try taking a shower. The water flowing from the spout should head straight to your showerhead. If your shower streams water perfectly and you don’t notice any water leaks from the bathtub spout, congratulations!

If, however, the issue persists or you have a more complicated shower setup, seek professional help. A professional plumber will ensure that your home’s water ends up where it’s supposed to be.

Avoid Shower Diverter Problems

Prevention is better than cure.

You can reduce strain and increase the life of your shower diverter by always releasing the diverter to allow for water circulation from the tub faucet for a few seconds before turning off the water.
