Can anyone tell me how to pull the grids form a Haywrad DE filter (4820) I noticed there is a threaded bolt and nut on the top of the grid unit, but the incoming and outgoing plumbing pipes also tie into the plastic housing type unit. Do I have to undo the plumbing lines? I recently cleaned mine but just hosed the grids with it in the the filter housing as I was unsure on pulling them out.
Any direction is appreciated.
Thanks,
Rob
