Hm... I'm going off Kozo's tables here (other boiler codes may vary)... For a plain cylinder boiler, 0.040" wall thickness is ok for 30 PSI in 1.25"-ish tube. End caps should be 0.050"+ thick without stays. All silver soldered of course.zeeprogrammer said:Thanks Ian, JimN, Ron, Kevin.
Shred...thanks. Ah...DWV = drain/waste/vent. If I remember right, costs about $7 at Home Depot. Chrome plated brass.
Funny that...I bought one and about a week later I needed to replace the faucet in the bathroom. Drain was too short! Guess what I needed? Right...I have to make another trip to HD.
Hydro test calls for 60 PSI...Would I be right in assuming the working pressure should be half that? 30 PSI?
I think the OD is about 1 1/4" Would plain copper pipe from HD (if available) be better?
I look forward to any comments, words of warnings, words of wisdom. Thanks.
