I lost my footing and dropped my hayward micro clear de filter and a plastic part broke off the top manifold collector dex2400c .. i dont see any plugs to skip the element so i bought a new manifold .. I already have an air bleed assembly on this one so i just bought the manifold thinking it would have a hole for the air bleed assembly .. but there is no hole for it on this one .. i dont know if i can still use this new manifold without the air bleed hole or will I have to send it back and get the one with it?
