cement and primer and avoid any metal fittings. (You can use flexible hose of course, but PVC
looks cleaner to me.) Use LOTS of unions and ball valves in case you need to take anything apart later for modification or maintenance.
How many holes do have and what size and location? Do you have a weir or skimmer box?
