What is the purpose of a hot tub diverter valve?

A hot tub diverter valve controls the water flow within your spa. Diverter valves redirect the water to specific areas or components of your tub, such as the spa jets, water features, or different seating zones, to optimize your experience. There are also air diverter valves for hot tubs to direct the airflow within your spa. 

By adjusting these valves, you can change the water or air pressure and distribution to tailor it to your personal preferences. A properly functioning diverter valve ensures water passes through the spa filters efficiently, optimizing filtration and maintaining water clarity.

What are the signs of a broken hot tub diverter valve?

If you notice any of the following signs, it’s crucial to shop for a tub diverter valve replacement to maintain the overall functionality of your spa and prevent further damage.

• Difficulty redirecting water flow: A broken diverter valve may make it challenging to adjust water direction or cause water to flow only from one side.
• Inadequate pressure in spa jets: If your jets lack pressure, this can also indicate a diverter valve malfunction, affecting water distribution.
• Leaks around the valve: Visible leaks near the diverter valve suggest there might be some damage, compromising the tub’s efficiency.
• Unusual noises: Strange sounds during water redirection may indicate internal damage, signaling the need for a tub diverter valve replacement.
• Reduced water temperature: If certain areas of your tub experience a drop in water temperature, it may indicate a faulty diverter valve, affecting the overall heating process.

What should you do if the hot tub diverter valve fails?

When facing issues with a malfunctioning hot tub diverter valve, start troubleshooting by checking for visible leaks or obstructions. Ensure the valve is properly aligned and not stuck. Test each setting to identify specific malfunctions, such as inadequate pressure or water flow. If problems continue, consult your hot tub manual for support or contact a technician to diagnose and address any issues.
