JasonLion said:Definitely waste. The waste setting moves the water more quickly. Also, on backwash, all of the water goes through the sand filter backwards. Any dirt in the water being pumped out would go back into the pool as soon as the system was put back to filter mode. Using backwash wouldn't be a huge problem, just not as efficient and messier.
is it normal that the water drains from the skimmer? isn't there a drain at the bottom? do I need to plug the skimmer somehow?
it is strange. in doubt I just turned things off, but it means that my pool as drained to about 20cm or so..
