What DE filter is a direct replacement for this unit? I really do not want to re-plumb, as original install left no room to modify the pvc pipes.

Hello Rick.  According to the manufacturer, there is no direct "drop-in" replacement for the Pentair Nautilus Plus NSP36 DE Filter.  If space and minimal re-plumb are strong considerations, you may wish to consider a cartridge style filter.  A cartridge style eliminates the backwash valve and typically has a smaller footprint.
