I have an old Hayward EC45 DE filter on my pool. I was just given a less-than-perfect EC40 for parts. Looking at the two, the main basin appears to be the only difference -- the EC40 is about 6 inches shorter than the EC45. All other parts appear to be identical.

Since it is smaller, it would look nicer if I swapped over to the EC40 basin, but I'm wondering if I'm missing something? Seems it uses the same amount of DE, has the same number & size tubes, etc, so the flow rates and capacity and such should all be the same.

Any thoughts?
