I have been reading about vacuuming and saw someone mention 'vacuuming to waste' I research that a bit and see that some filters have a multiport valve that allows them to perform different functions. Do all filters have these? I found the manual for my pump and nowhere does it mention a multiport valve, back washing, waste, etc.
Am I missing something, or do I just vacuum directly into my skimmer?
Thanks
