a licensed contractor only.
5. Option: To prevent damage to the code valve while soldering,
cool the valve by wrapping a wet rag around the body of the
valve.
6. Heat the joints with a torch. Apply solder to each joint.
Continue to apply heat sufficient to keep solder liquid.
7. After solder has filled the entire joint area, remove heat and
allow the joint to cool. Do not move or disturb.
8. Slide compression nut over 1/4” copper tube followed by
compression sleeve.
9. Insert tube into valve fully and tighten nut.

5Mount the self-tapping saddle valve on either a cold or a hot
water pipe. A side or top mount is best to avoid clogging from
pipe sediment. Connect 1/4” O.D. tubing to the saddle valve.
• Copper tubing requires a brass compression nut and
brass sleeve.
• Plastic tubing requires a brass insert inside the
tubing, a plastic sleeve on the outside with a brass
compression nut.
