I have read online, after the fact, that acid core solder should NOT be used when sweating copper pipe. When I bought this at the hardware store I was told it was okay. Now I am questioning it. What will happen? Will it corrode over time or is it a health hazzard for drinking water?
Hard to ad much to the already thorough answers, but dyno tests have shown that the stock intake flows enough for the stock engine. if however, you ad a bunch aftermarket goodies, (upper/lower intake, heads, cams, exhaust etc. etc.) then the extra flow from your CAI will be usefull.
Resin flux must be used for electrical work. Acid flux is correct for copper water piping. . It is handy to have flux in the core. Lead free solder is required by local building codes.
Hi, Jester! When sweating copper pipe, the flux is normally separate and the solder should be 95/5 (lead solder is not to code in most localities anymore). Make sure to clean each joint by sanding with emery cloth or specialized wire brushes. In order for each sweat joint to hold, there must be NO moisture at the point of connection. Also remember that your torch is used to heat the pipe and NOT the solder. The connections are correct if the solder 'flows' into the joints. Hope this helps! John H
