Regulator valve that stabilizes incoming mains water pressure to prevent burst pipes and dripping water heaters.
What is Pressure Reducing Valve (PRV)?
A pressure reducing valve lowers excessive municipal water pressure (which can exceed 6 bar at night) to a safe 3–3.5 bar, protecting boilers, electric water heaters, and ceramic faucet cartridges.
When you encounter it in an emergency & typical cost
Essential if your water heater drips from its safety valve or if pipes bang/whistle when closing taps. Installation: €90-160.
