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.

If you develop a leak in a copper pipe, it usually is possible to replace just the piece of pipe that is leaking and leave the sound plumbing around it intact. Soldered joints in copper plumbing may look permanent, but with some basic tools they can be disassembled and repaired relatively easily.ently begin to heat the joint with a propane torch; you are aiming to heat the joint evenly and soften the solder without overheating the copper pipe. If the joint starts to discolor stop applying heat and wait until it cools before continuing heating.
