Escape pipe shouldbe 30 cm higher than water heater. The valve's water level has been adjustedbefore they leave factory, use the screw bolt in the upside of the valve canadjust it again if needed, and water valve will rise when tightening the boltand drop conversely. It is a normal phenomenon if there is a little spillingwater when the solar water heaters vent pipelines in light heating. To preventblockage, the pipeline should be rinsed out before installing the valve.Double-pipeline mode has built-in check valve, single-pipeline mode isconfigured using articulated water-meter check valve, it can prevent reflexwater when the water stops. As long as installing the check valve in thearticulated water-meter position, this has solved the trouble of the users thatcan't install the check valve inconveniently.
Mode | Single-pipeline |
| Function | Auto watering, auto closed when full water, auto opened when use water,configured using articulated water-meter check valve. |
