Installation of air valves:
1. Air valves must be installed vertically, i.e. the buoy inside them must be kept in a vertical state to avoid affecting the exhaust.
2. When installing, it is better to install with the partition valve, so that when it needs to be removed for repair, the system can be sealed and the water will not rate out.
3. It is generally installed at the highest point of the system, which is conducive to improving the exhaust efficiency.
4. Low system pressure is not only harmful to exhaust, but also increases the possibility of leakage.
