FAQs

What is the purpose of the Tower Auto Bypass Valve?

It regulates flow through the boiler and reduces system noise by maintaining a minimum flow rate, especially when TRVs are installed.

What size pipework does this valve fit?

This valve fits 22mm pipework.

How do I set the pressure on the valve?

You will need to use a pressure gauge to set the valve within the specified pressure range for your boiler. Consult your boiler manual or a professional.

Where should the bypass valve be installed?

The valve is typically installed between the flow and return pipes of the heating system, after the pump and before the boiler.

How do I know if the valve is working?

You can monitor the system pressure. When TRVs close, the valve should open, maintaining a consistent pressure.

Can I install this valve myself?

If you are comfortable with plumbing, yes, but professional installation is recommended. Always ensure the system is depressurized before beginning any work.

What should I do if the valve leaks?

Turn off the heating system and consult a qualified plumber or HVAC technician.

Troubleshooting

System noise persists after installation.

Check the pressure setting. It may need adjustment. Also, ensure all TRVs are functioning correctly. If the noise continues, consult a qualified HVAC technician.

Boiler overheating or shutting down.

The bypass valve may not be opening correctly. Check for blockages in the valve or associated pipework. Ensure the valve is installed correctly and that the pressure is set appropriately.

Setup, Compatibility & Care

Installation: The valve is designed for easy installation with a 22mm compression fitting. Ensure the system is drained and depressurized before installation. Follow the manufacturer's instructions carefully.
Compatibility: Compatible with most sealed heating systems. Ensure your system's specifications align with the valve's differential pressure range (0.1 to 0.6 bar) and flow capacity.
Pressure Setting: Set the pressure according to your boiler's specifications. Consult your boiler manual or a qualified HVAC technician for guidance. Incorrect pressure settings can lead to inefficiency or damage.
Maintenance: Regularly inspect the valve for leaks or unusual noises. No specific maintenance is required, but an annual system checkup by a qualified technician is recommended.
