2. I find it interesting

3. We like to learn new things

4. We like to understand

5. How things work

6. How things break

7. How to use non-standard approached to solve problems

8. Others can learn from my experience, troubleshooting process, etc...

9. I had fun creating the episode titles.

10. Pinhole leaks in copper pipe

11. Causes – Note plumbing is around 40 years old and original to house

12. Poor quality copper Shoddy installation

13. Failure to de-bur pipe before soldering

14. Not properly hung from joists

15. Pipe on pipe

16. Pipe on steel wire

17. Bad soldering technique

18. Lumpy solder

19. Flux residue

20. Excessive flux

21. Hard water

22. Only some neighbors experiencing the same issue, and their houses were constructed by the same builder.

23. Learn more about copper pipe corrosion

24. How to Stop Copper Pipe Corrosion - This Old House YouTube Channel

26. High Water Pressure

27. Normal = 60-80 PSI

28. Tested at 63 PSI = GOOD!!

29. Damage

30. Water leaks caused damage to drywall in parts of my house and to items stored in my garage.

31. Leaks in some areas can sometimes go unidentified for long enough to do extensive damage and even lead to dangerous mold growth.

32. Possible solutions

33. Short term

34. Patch

35. Epoxy kits

36. Can be inconsistent

37. May not bond to corroded pipe

38. Some require turning off water and dry pipes

39. Water activated tape

40. Access around pipe

41. May not bond to corroded pipe

42. Some require turning off water and dry pipes

43. Solder on patch

44. Expensive

45. Requires clean dry pipe exterior

46. Requires draining the pipe

47. Might as well cut out the leaking section and replace

48. Repair Clamps

49. Fast

50. Strong

51. Can be used while pipe is under pressure

52. Minimal clearance needed

53. Examples
