Adjustable pressure without tools: The pressure can be adjusted without special tools. Turn counterclockwise to decrease pressure. The preset reduction is within the safe range of 22.5 KG and is ready to use directly. Water hammer protection and system stability: The water pressure relief regulator helps prevent water hammer, increases system pressure stability, and reduces leakage faults when water flows quickly. Inlet compatibility and installation: The regulator reduces pressure to the 3way ball valve at the water purifier inlet, or can be installed in series with the water purifier inlet pipe. It is suitable for installation in most water purifiers, faucets, and other water equipment. Performance at varying pressures: It greatly increases water pressure at low water pressure, while maintaining stability of water flow at water pressure. Use scenarios: Home water purifier setup with low incoming pressure: install to ensure consistent, reliable purification flow. Faucets or fixtures prone to water hammer: use to mitigate pressure spikes and protect plumbing and fixtures. Inline filtration systems or multiinlet configurations: install between supply line and purifier inlet to stabilize pressure across multiple outlets. Compatibility and practicality: Designed to work with standard plumbing connections targeting the water purifier inlet and related water equipment, offering a straightforward, tool adjustment and reliable performance.
