Yes, the lid on a D.E. filter system needs to be installed properly to ensure a secure seal and prevent leaks. Before installing the lid, make sure the O-ring is clean and properly lubricated with pool filter O-ring lubricant. Press the lid down fully into place, then tighten the locking ring until it is securely locked in position. Proper installation of the lid and O-ring is important for maintaining a good seal and safe operation of your filter system.
