Owing to effect of the decreased upstream pressure, the drain valve opens and discharges water from the central zone. 4 - PRESSURE REVERSE (RETURN OF FOW) When pressure is reversed, the first check valve protects the water mains from possible contamination. The drain valve opens and discharges the contaminated water. Cold and hot water supply and distribution systems UNI 9182/87 Precautions against contamination (Section 8 subparagraph 8.2.2) During operation, all the necessary measures shall be taken so that contamination of the water by external agents shall never occur... omissis it is forbidden to add water to sanitary appliances, tanks, expansion vessels when open to supply make-up water to heating systems or the like to feed users directly, where said users could contaminate drinking water from which they are derived unless through the installation of back flow preventers with regulated reduced pressure zone.
