I haven't had my Hayward Progrid DE6020 filter apart for several years; I have back issues and couldn't catch somebody to help me remove it. Last time I paid a pretty dependable pool tech to clean it, and he apparently din't clean or lube the output elbow o-ring, thus the removal issues.
So, the whole assembly was sticking at the o-ring. When I finally got it apart (I built a sky hook from some long 2x4s, a hinge, some allthread, and a coupling nut), I managed to crack the [ABS?] top collector manifold, and that took the half of the nipple off about 3 or 4 of the filter elements (ouch!) See photo.
The manifold inlets for the individual elements have fingers inside the orifice to align the elements properly. Some leakage must occur there by the very design. I am trying to decide if I can get by with the damaged elements and a new manifold.
The manual shows the individual elements to have a part number of DEX6000DA. Does this seem to be the right part? It is totally confusing out there on the web.
