How to Vacuum to Waste with Sand Filter: A Step-by-Step Guide
To vacuum to waste with a sand filter, first, turn off the filter system and remove the skimmer basket. Then, attach the vacuum hose to the vacuum head and insert it into the pool. Turn the filter system back on and vacuum the pool debris thoroughly. Once done, turn off the filter system again and switch the multiport valve to the waste position. Turn the filter system back on to discharge the water away from the pool and backwash the filter afterward to avoid clogging.
