How to Fix a Shower Diverter

So, What Exactly Is A Shower Diverter?

A shower diverter is a device that allows you to control the direction of water flow in a shower or bathtub. In a standard shower setup, the diverter valve is usually located on the tub's faucet or a separate diverter knob or lever on the wall. When you turn on the shower, the diverter redirects water from the tub spout to the showerhead. Equally, when you want to use the bathtub, you can adjust the diverter to send water down the tub spout.

Common Shower Diverter Issues and How to Fix Them

• The Valve Won’t Engage

This issue often stems from a buildup of mineral deposits or debris. Start by turning off the water supply, and then remove the diverter handle or knob. Clean the diverter's internal components, including the valve stem and seat, using a mixture of white vinegar and water. If the valve still won’t engage, it may be necessary to replace the diverter valve.

• Noisy Shower Diverter

These noises are usually due to friction or worn-out parts within the valve. To fix this, disassemble the diverter and apply a silicone-based lubricant to the moving parts. If the noise continues, call a professional plumber to replace the diverter.

• Leaking Diverter

A shower diverter can leak due to many reasons. To address a leaking diverter, you'll likely need to replace it. Replacing a leaking diverter is a job that should be left to professional plumbers. Ensure you choose a diverter that matches your shower system and follow the manufacturer's installation instructions carefully to prevent leaks in the future.

• Stuck Diverter

The diverter can get stuck in one position, either sending water only to the showerhead or only to the tub spout. Begin by shutting off the water supply. Then, remove the diverter handle and inspect it for any visible damage or corrosion. If everything looks fine, consider using a penetrating lubricant to loosen the diverter's internal components. If this doesn't work, consider replacing the diverter.

Trouble Switching the Water from the Tub to the Showerhead

This issue often results from wear and tear on the diverter's handle or knob. If you're experiencing difficulty, replace the handle or knob with a new one designed for your diverter system. Ensure it's properly secured for easy operation.

Decreased Water Pressure

If water pressure at either the showerhead or the tub spout has significantly decreased, start by cleaning the shower diverter's internal components to remove mineral deposits or debris that may be causing the issue. If the problem persists, you might need to replace the diverter valve to restore proper water pressure.

Corroded Shower Diverter

If corrosion is the culprit, it's best to have professional plumbing service replace the diverter valve entirely. Choose a high-quality replacement and ensure it's installed correctly to prevent future corrosion-related issues.
