Assembling the Valve Assembly onto the Barrel can be tricky. It involves carefully aligning the three small Pilot Holes on the bottom of the Valve Assembly with the corresponding holes in the Barrel and using the right kind of glue and not too much of it.
1) Make an alignment tool to align the Valve Body Pilot Holes with the Barrel Pilot Holes. Get a piece of stiff wire about 1 foot long, such as 10 ga Romex. Make a small 90° bend in the end so that 1/4" sticks out. Wrap the wire around a stick and tape it in place. 2) Before you use this tool, scrape the Barrel clean of old glue and dirt. |

4) Also remove the Spool Valve so you can see the Spool Valve chamber and the three Pilot Holes. 5) Then put a small amount of silicone glue, such as silicone bathtub caulk, on the Valve Assembly bottom so that there is only a thin layer of glue on it. Don't use any other kind of glue as the Valve Assembly would be impossible to remove later. If you use too thick a layer of glue near the Pilot Holes, the glue will get in the holes and seal them or restrict the flow. Then you have to take the Valve Body off the Barrel, clean out the Pilot Holes, and start all over again. Use a small screwdriver to scrape out any glue in the Pilot Holes. |

6) Then put the three Pilot Hole o-rings in the corresponding holes. Always use new Pilot Hole O-Rings part 10-1313.

8) Gently put the Valve Assembly down onto the Barrel, making sure the tip of the wire also slides into the center hole of the Valve Assembly. That's the initial alignment.
