It’s natural to think of water as an inert, harmless liquid. But for the water running through municipal distribution systems, great care is taken, and extensive treatment is required to ensure clean, safe drinking water. The source water, whether it comes from a lake, river, reservoir or aquifer, inherently contains contaminants in the form of both dissolved solids and bacteria that requires treatment.
Risk of pipe failure and water quality issues are things that few builders can afford. Yet, many expose themselves to this vulnerability by delegating plumbing material selection to their plumbing contractors. It’s important to trust your contractors, but not at the expense of your business.
Discover why you should make the switch to FlowGuard Gold® CPVC
The first post in our Healthy Home series reviewed the difference in the biofilm growth potential of PEX and CPVC piping while the second outlined the dangers that can occur if chemicals such as pesticides permeate PEX piping.
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.
Research conducted by NSF International indicates that one-third of PEX plumbing piping samples tested per the NSF 61 drinking water standard exceed California drinking water standards for methyl-tert-butyl-ether (MTBE).
Recently, dangerously high levels of copper were found in several luxury condos built within the last decade, prompting city officials to take action and caution residents against drinking and cooking with tap water.
