The backwashing of the valveless filter cannot stop automatically
Thread Content
The newly installed valveless filter doesn’t stop automatically during backwashing – why is it continuing to backwash? ?
Check the siphon rupture pipe and its valves and flanges for any air leaks. Or turn off the water inlet valve, wait until the flushing is complete, and then try turning it back on. Is the water level of the water seal in the drain groove below very low? Otherwise, replenish water or raise the water barrier.
If it can’t stop, water must be entering and coming out directly through the backwash; closing the water inlet valve should solve the problem
The water inlet valve can be turned down a bit; it might be caused by too much water inflowing.
