Extended Product Information
FAQs
Can I install this on an 8mm pipe?
Yes, the product is supplied with adaptors specifically designed to fit 8mm, 10mm, and 15mm pipework.
Is this valve suitable for smart home systems?
No, this is a standard thermostatic radiator valve. It does not contain electronic components for smart home app integration.
Does this work with open-vented systems?
Yes, the Pro Plus Angled TRV is fully compatible with both sealed (pressurized) and open-vented central heating systems.
Why is it called an 'angled' TRV?
The term 'angled' refers to the body shape, which allows the valve to connect a pipe coming from the floor or wall to the bottom inlet of the radiator.
Do I need special tools to install this?
You will need standard plumbing tools including an adjustable spanner, pipe cutters, and potentially a basin wrench or pipe grips to remove the old valve.
Troubleshooting
Radiator stays cold even when the TRV is turned up
The internal valve pin may be stuck due to lack of use. Remove the head, locate the small pin, and gently press it down to ensure it moves freely.
Water leaking from the valve connection
Ensure the compression nut is tightened sufficiently and that the correct adaptor size was used for your specific pipe diameter.
Valve makes a whistling noise
This often indicates the system pressure is too high or the flow is restricted. Ensure your central heating pump settings are correctly balanced.

Setup, Compatibility & Care
Installation
Ensure the heating system is fully powered off and cooled.
Drain the central heating system to below the level of the radiator being serviced.
Remove the old valve and install the Pro Plus body using the appropriate size adaptor for your pipe diameter (8mm, 10mm, or 15mm).
Use PTFE tape or a suitable pipe sealant to ensure all threaded connections are watertight.
Refill the system, bleed all radiators, and check for leaks once the system reaches operating pressure.
Care and Maintenance
Periodically wipe the valve with a soft, dry cloth to keep the finish clean.
Avoid using abrasive cleaners that could damage the valve body coating.
At the end of the summer season, turn the TRV to the maximum setting to prevent the valve pin from sticking due to mineral buildup.
