This manual provides instructions on how to winterize a Rain Bird sprinkler system.
This guide explains how to winterize sprinkler systems to avoid damage from freezing temperatures. It covers three main techniques: the manual drain valve method, the automatic drain valve system, and the air blow-out practice. Special attention is given to removing water from pipes, valves, and sprinkler heads before freezing occurs.
The document provides detailed instructions for each method, including safety precautions and specific procedures. For manual drain valves, it outlines design requirements like proper piping slope and installation over dry-wells. For automatic drain valves, it specifies installation locations and warns against using them on mainlines. The air blow-out section details compressor requirements, pressure limits (50 psi), and step-by-step procedures for activating zones safely.
| Maximum Air Pressure | 50 pounds per square inch (psi) |
|---|---|
| Required Air Volume | 10 to 25 cubic feet per minute (CFM) |
| Automatic Drain Valve Model | 16A-FDV |
| Drain Valve Thread Size | 1/2" or 3/4" male pipe threads |
The three techniques are the manual drain valve method, the automatic drain valve system, or the air blow-out practice.
Air pressure must not exceed 50 pounds per square inch (psi) during the blow-out procedure.
