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.

Traditional solder that used to be used for soldering in the electronics industry used to be a mixture of tin and lead. Different types of solder are used for different purposes. Solder is of course used in plumbing. The type of solder used for electronics usually contains 60% tin and 40% lead.This is often known as 60/40 solder. It is what is termed a Eutectic Mixture. Although this is a chemical term, basically this type of mixture melts at a temperature well below that which might normally be expected.older is of course used in plumbing.
