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.

Chloride of zinc, or âkilled acid,â is used as a flux when soldering clean galvanized iron, zinc, copper, and brass. When the material to be soldered is tin plate, bright copper, or lead, rosin is used as a flux, and when melting has a tendency to penetrate into the lock or seam.There are several kinds of soldering salts and non-corrosive fluxes on the market, which are being used with good results by the sheet metal trade.hloride of zinc, or âkilled acid,â is used as a flux when soldering clean galvanized iron, zinc, copper, and brass.
