Install drain for backflow preventers with atmospheric -vent drain connection with air -gap <br />fitting, fixed air -gap fitting, or equivalent positive pipe separation of at least two pipe <br />diameters in drain piping and pipe -to -floor drain. Locate air -gap device attached to or <br />under backflow preventer. Simple air breaks are unacceptable for this application. <br />3. Do not install bypass piping around backflow preventers. <br />Install water regulators with inlet and outlet shutoff valves. Install pressure gages on inlet and <br />outlet. <br />C. Install balancing valves in locations where they can easily be adjusted. <br />D. Install temperature -actuated, water mixing valves with check stops or shutoff valves on inlets <br />and with shutoff valve on outlet. <br />E. Install Y -pattern strainers for water on supply side of each water pressure -reducing valve <br />solenoid valve and pump. <br />F. Install outlet boxes recessed in wall.
