How to Properly Vacuum to Waste with a DE Filter for a Sparkling Clean Pool
To vacuum to waste with a DE filter, first turn off the pool pump and close the skimmer and return valves. Connect the vacuum hose to the vacuum head and lower it into the pool, priming the hose by filling it with water. Then, turn on the pump and allow it to run until the water level drops below the vacuum head. At this point, turn off the pump, switch the valve to “waste,” and turn the pump back on. The water from the pool will be pumped out and bypass the filter, allowing for easy removal of debris.
