In the first post in our Healthy Home series, we reviewed the important issue of biofilm formation in residential piping and the difference in the biofilm growth potential of PEX and CPVC piping. For this post, we’ll examine another issue that can impact residential water quality: chemical permeation.
Residential home builders have made significant progress in improving the air quality issues that can arise in today’s tightly built, energy efficient homes. Turning to materials with lower air quality impacts and increasing mechanical ventilation in accordance with ASHRAE IAQ standards has allowed builders to achieve both the efficiency and indoor air quality today’s health and energy conscious consumers are seeking.
