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.

Steps. Cut the pipes to the right length using a hacksaw or a copper tube cutter. Remove the burs with a wire brush or file. Clean the end of the copper pipe with a special cleaning brush.Clean until the surface is bright all around. Clean the inside of all fittings.Apply soldering paste to the cleaned ends of the pipe and the insides of the cleaned fittings. Attach the fitting to the end of the pipe and use a propane flame in the middle of the fitting to heat both ends at the same time. Donât apply heat directly to fluxed area.lean the inside of all fittings. Apply soldering paste to the cleaned ends of the pipe and the insides of the cleaned fittings.
