Efficient pressure relief - Align the pressure relief opening with the drain opening of the water tank during installation to prevent water from splashing onto the floor or onto you. This design ensures safe operation during relief. Safe water extraction - After the booster pump engages, firmly tighten the water inlet pipe and the filter to prevent contaminants from entering the pump housing and to maintain pump performance. Clear pressure readings - The pressure regulator provides clear measurements for normal supply pressure at 0.3 MPa and high inrush pressure at 0.4 MPa. Typical tests for water lines range from 0.8 to 1 MPa, and tests for household lines last 2 to 4 hours depending on the installation environment. User-friendly seal assembly - Install the hose connection last to avoid damage to the high-pressure hose. The gasket ring is factory pre-installed, so you do not need to fit it on delivery. A spare set of gasket rings is included for later replacement. Applications and use scenarios - Residential water supply with a booster pump to maintain stable pressure and minimize splash during relief. - Outdoor cleaning or garden irrigation systems that require consistent pressure and reliable pump protection. - Car washing or other high-pressure tasks where a controlled relief and clear pressure readings aid safe and reliable operation.
