Intent 1:
To limit the probability that inappropriate design
will lead to:
- inadequate flow volume, which could lead to inefficient
cleansing of fixtures,
- lack of a means of adjusting flow rate to suit varying
water pressures, which could lead to incomplete flushing action, or
- back-siphonage, which could lead to contamination of
the water supply.
This is to limit the probability of
unsanitary conditions, which could lead to harm to persons.
