have the following similar parts: 1/4" long nipple (4),
1/4" x 1/4" short nipple (6), fitting B (13), and union
set (5). Use thread tape on the threads of
both nipples.
2. Remove the 1/4" plug on the inlet side of the main

3. Thread the 1/4" long nipple (4) into the main valve (1) in
place of the 1/4" plug.

pressure pilot at fitting "A" (14) and to the top of the
tee (12) and tighten. Note: Make sure the downstream
sensing port (15) on the pilot faces upstream.
