Heated pipe, fittings, and solder are capable of producing serious burns. Use pliers to
handle work being soldered and unsoldered.
6. When solder is shiny and fluid, use pliers to remove valve (5) from pipe (4).
7. Allow pipe to cool.
8. Remove valve handle and stem from new valve as described in steps 2 through 4 above.
9. Use sandpaper to clean pipe and valve to be joined.
10. Apply flux to pipe and valve at joints
11. Join pipe (4) and valve (5).
12. Apply heat to valve (5) with torch.
When soldering, remember to apply heat to where that you want the solder to flow, and
then apply the solder to the part you've heated. The part being soldered will melt the
solder and draw the solder into the joint. Do not apply heat directly to the solder, as it will
drip and splatter.
13. Apply solder to valve (5) at joint.
14. Allow joint to cool.
15. Clean cooled joint with sandpaper.
16. Inspect joint for thorough soldering. Solder should show as a thin silver colored ring around
circumference of joint.
17. If joint is insufficiently soldered, repeat steps 5 through 16 above.
18. Replace valve stem, and secure with packing nut.
19. Replace valve handle, and secure with nut.
20. Apply anti-seize tape to threads. Using two pipe wrenches, tighten union (1).
