If made of warmth tolerant plastic, this ratio really should be even less in order to avoid interesting points more info in which biofilm advancement could manifest. In ambient temperature distribution systems, certain treatment should be exercised to prevent or lessen lifeless leg ratios of any sizing and provide for full drainage.
