What it is
The RWC 2.1/8 Bar Compact Inlet Control Group is a cold water inlet control assembly for unvented hot water cylinders. It combines the pressure reducing valve, strainer and expansion relief functions into a single compact manifold. It is fitted on the cold water supply to the cylinder to regulate incoming mains pressure and protect the cylinder and its safety devices.
Signs this part needs replacing
- Reduced or erratic hot water flow at the taps, often caused by scale or debris blocking the strainer or reducing valve seat
- Water weeping or dripping from the valve body, relief port or connections
- Discharge from the expansion relief valve with no fault at the cylinder
- Inlet pressure at the cylinder drifting above or below the set pressure, causing poor performance or repeated safety valve operation
- Noisy or vibrating operation at the inlet group when taps are opened
Before you order
- Confirm your cylinder make and model against the fit list above
- Check the pressure rating of the existing inlet group matches the replacement
- Inspect the pipework connections and available space, as the compact body must suit the installation
- Confirm whether a balanced cold water take-off is required for your system
