LEGEND - 0782115154, 115-154, This mixing valve comes in a T shape and is made for radiant heating.

Backflow prevention assemblies are designed to prevent contaminated water from mixing into clean municipal water supplies, which are usually used as drinking water. Contaminants like sediments, bacteria, and fertilizer are a major public health hazard, so there are regulations in place that require certain buildings to have backflow preventers installed.

If something happens that causes a drop in pressure in the water mains, such as the use of a nearby fire hydrant or a burst pipe, contaminants can flow back through the sprinkler head because of the pressure difference. This can introduce fertilizers and pesticides into potable water.

A RPZ reduced pressure zone backflow preventer's design differs from the DCV by featuring an additional differential release valve as a mechanical fail-safe device which will open and dump contaminated water to isolate the mains water supply.
