- Efficient pressure relief: Align the pressure relief port with the water tank outlet during installation. This alignment prevents water from spraying onto the floor or back onto the device when releasing pressure. - Safe water intake: After locking the boosting pump, securely tighten the water inlet tube and the filter. This helps prevent contamination of the pump body and protects its operation. - Clear pressure readings: The built-in pressure gauge shows clear values: normal line pressure at 0.3 MPa and boost pressure at 0.4 MPa. Typical water supply tests range from 0.8 to 1 MPa, and household pipeline tests are maintained for 2 to 4 hours depending on the environment. - Easy gasket setup and maintenance: Install the hose connection last to avoid damage to the high-pressure hose. The gasket ring is preinstalled from factory, so no installation is required on delivery. A replacement gasket set is included for future maintenance. - What it does and why you need it: Provides controlled, safe pressure relief, protects the pump from contamination, and offers clear, actionable pressure readings to ensure proper operation of your water system. - Compatibility and use: Designed for use with standard water tanks and boosting pumps. Includes a preinstalled gasket and a spare gasket kit for ongoing maintenance. - Practical use scenarios: 1) Home water system upgrade: Install with a boosting pump to ensure stable pressure and prevent splashes during pressure release. 2) Pressure testing and verification: Use the gauge to verify normal and boosted pressures during routine piping tests, typically in the 0.8–1 MPa range, with tests lasting 2–4 hours as appropriate. 3) Maintenance and gasket replacement: Use the included replacement gasket set to maintain a secure seal during routine service or after long-term use.
