How many types of water pipes are there?

How do you size water pipes?
Three Steps to Sizing Plumbing Piping Systems
- Add up the total number of water supply fixture units (wsfu) required in the facility.
- Estimate demand using the table from the IPC that correlates wsfu to expected demand.
- Size the pipe using demand vs. friction loss curves found in the IPC charts.
What is the best pipe for main water line?
HDPE (High Density Polyethylene) pipes are a considered the best choice for underground water lines. What makes this type of piping so great? HDPE pipes are non-toxic, tasteless, and considered a green building material. The pipes are designed to be high crack- and corrosion-resistant.

Which is stronger schedule 40 or 80?
Schedule 80 pipe is designed with a thicker wall. This means the pipe is thicker and stronger, and as a result it can handle higher pressures. Schedule 40 PVC pipe is strong, rigid, and can handle pressure applications. For jobs that require a higher pressurization though, schedule 80 pipe is better suited.
