4710 pipe should require 10-15% more force than 3408 to straighten, but you may have to adjust a bit to find the best pressure setting for the conditions you are in. If the pipe has been stored in the hot sun, you may have to drop pressures a bit, and in cooler climates, you may have to increase a bit, just as you would have to for 3408 or any other resin. If 3408 requires 500 PSI in at a given temperature, you should be at about 550-575 PSI for 4710 (+10%-15%).
Please post your results if you don't mind, thank you! John
