The Pipe Install Horizontal 22mm Plastic Estimating Calculator is designed for use with PlansXpress.

If you have created your estimate based on a PlansXpress drawing, the Plastic Water Pipe data from your PlansXpress drawing is imported into multiple separate EstimatorXpress Estimating Calculators.
