All of the following are common errors in the installation and use of a graywater system, except:

Excessively intricate systems that add no value
Heeding local regulations and recommendations for system design
Setting up graywater irrigation for lawns
Using potable water plumbing design and fittings

Explanation

Answer: B - Following regulations and recommendations specific to the graywater system install area is a smart action, not an error. On the other hand, “overdoing” system design and installation to no net benefit is a financial error. Likewise, irrigating lawns with graywater or simply using plumbing installation procedures and products designed for potable water are both errors that can have consequences for human health.
