RE: Knee wall - foundation wall 'hinge'. You have an 8' high wall that is continuous and that is much stronger than a wall with a hinge. An 8' high masonry wall is routine irregardless of the amount of unbalanced load.
Flux and Solder. For decades, copper pipe has been one of the most common materials used to distribute water throughout the home. The most common technique used to join sections of copper pipe is called soldering.In the soldering process, heat is applied to the copper joint where the pipe and fitting meet and the gap between the joint is filled with molten metal.This guide will help you identify the flux and solder appropriate for your project, so you can feel confident youâre getting the job done correctly.n the soldering process, heat is applied to the copper joint where the pipe and fitting meet and the gap between the joint is filled with molten metal.

Soldering gutters is similar to soldering water pipes, using the same tools and following similar precautions. The ends of the joins must be clean and bare to properly accept the flux and solder. This is done by taking emery or pipe-cleaning paper and rubbing the ends until the metal is bare and shiny.
