Dimensional data, pressure ratings, pressure drop table, typical circuit lengths and other technical specifications of PEX tubing used in system sizing and calculations.

The minimum flow rates are based on water velocity of 2 feet per second and maximum flow rates are based on 4 feet per second. This document provides a chart showing the minimum and maximum flow rates in gallons per minute (gpm) for various sizes of copper pipe, PEX pipe, and PEX-AL-PEX pipe.

PureFlow PEX red, blue, and white tubing can also be used in “continuously recirculating” plumbing systems at temperatures of up to 140°F while still maintaining excellent chlorine resistance. Design temperature and pressure ratings for Viega PureFlow PEX are 160 psi @ 73°F, 100 psi @ 180°F, and 80 psi @ 200°F.

In a typical single-family residential plumbing system, PEX and copper piping systems will deliver sufficient volumetric flow rates to the plumbing fixtures when using the same nominal size tubing.

Sizes: 3/8", 1/2", 5/8", 3/4" and 1". All Everhot PEX tubing is marked with nominal (CTS) and OD sizes, applicable ASTM standards, third party certifications (NSF-rfh), temperature and pressure ratings, material designation code, manufacturing date / time / codes and footage on every 5ft of tubing. Radiant heating systems.

Use this chart to determine if a given GPM in a DHW Re-Circ return is too high. Re-Circ 140° F Max. These charts can to be used for dedicated return pipe sizing, or to verify if existing pipe is appropriate !

Everhot Non-Barrier type PEX tubing is designed for use in hot and cold potable water distribution systems in residential, commercial and manufactured housing applications. It is also suitable for continuous hot water recirculation and for use in open-loop hydronic applications.
