I have a EC 45 Filter. The Bottom round plate that retains the filter fingers broke. I want to replace top and Bottom. What or where should I look. Photo attached.

Hi, Bob. The Top is P/N ECX1004A and Bottom is P/N ECX1004. The EC40 parts are interchangeable with the EC45.

I have an EC60 DE filter and the finger holder portion of the filter appears to be in 2 parts (a top ring and a bottom ring-each having holes in them). While bumping my pool The bottom of the bottom ring broke off at the shaft. The top part number (ECX1104)shows different views of the part, where the bottom one (ECX1103) does not. The bottom ring on my the center where the shaft goes in flairs out a bit. Can you send me what the bottom of the disk looks like so I can tell if it is correct

Hi George, This is the only photo we have of the Bottom Tube Sheet which will fit the Hayward EC60 filter.

Turn off power to pump. Remove filer cover/filter tube assembly. Remove bump handle by removing small bolt. Lift cover away from filter tubes. Remove 16 small bolts to separate upper and lower tube sheets. Remove upper tube sheet and replace with new part. Now is a good time to check the center shaft and shaft o-rings condition,replace as necessary. reassemble, replacing all bolts (align cover gasket carefully).
