I’ve been using this 2-speed pump continuously for the last 4years +. Lid has been off dozens of times. Finally, getting the pool replastered, the pump was off for 3-4 weeks, thanks to uncooperative weather. Plastering done, pool finally filled, pump wouldn’t pull water and I can’t prime it because the lid won’t come off. Tapped both directions with a hammer on the “ears” to loosen, the locking ring will move but lid won’t budge. Opened the drain at bottom of basket in case of air lock, to no avail. Totally at a loss what to do. Ordered a new lid, delivered today, but useless unless I get this one off. Help? Please.
