Friars Plumbcraft
Radiator Valve and TRV Fitting
Intended for homes with cold spots, noisy pipes, or rooms that overheat because old manual valves cannot regulate heat. We drain down or freeze the central heating pipework, remove stubborn manual valves, and install liquid-sensor thermostatic valves on your radiators. The result is room-by-room temperature control and a balanced, quieter heating circuit.

- ✓Bi-directional thermostatic radiator valve fitting
- ✓Matching lockshield valve installation
- ✓Pipe tail extensions and olive replacements
- ✓System freeze-kit isolation where possible
