Installation Procedure

CAUTION:

When assembling the Drip Zone Valve

Kit components, use just 1

⁄2 to 2 turns of Teflon

tape on male threads. Never use pipe dope. To achieve a leak-free thread connection, turn the

male fitting until it is finger tight, then add one or two more turns. Over-tightening can cause splitting and failure of the female threads.

Important: Ensure the Y-Filter, Jar Top Valve and

Pressure Regulator are installed in the correct flow orientation. Flow direction arrows are provided on each component. Refer to Figure 1 and Figure 2.

1. Using the Close Nipple, install the Ball Valve to the Jar

Top Valve inlet.

2. Remove the Bonnet Ring from the Y-Filter by turning

it counterclockwise. Remove the Bonnet and Filter Screen. See Figure 1.

3. Install the Y-Filter inlet to the Jar Top Valve outlet.

4. Install the Pressure Regulator inlet to the Y-Filter outlet.

5. Reassemble the Y-Filter components.

Note: Hand tighten the Bonnet Ring only – do not

over-tighten.

Important: Refer to the provided Toro Jar Top Valve,

Anti-Siphon (AVB) installation instructions for additional important installation and operating information.

6. To determine the recommended minimum/maximum

number of drip emitters per Jar Top valve, refer to the table below.
