The pipe-fitting formula for a 45-degree offset in plumbing is the length of a diagonal connector, known as the travel, times 0.707. To calculate rolling offset, when a pipe changes direction both vertically and horizontally, it is necessary to find the values for true offset, the setback and the diagonal.Know More
True offset is found by squaring the offset and adding the square of the rise value to equal the true offset squared. The square root is then found to determine true offset. With true offset determined, a pre-existing table can be used to find setback and diagonal values.
Plumbing often involves working on pipes hidden behind walls, in small utility rooms or in other tight spaces. Plumbers often work without direct access to pipes, for instance when working with underground sewer lines. In some cases, cameras are sent in to assess problems, and then plumbers use pumps lowered with cables to execute pipe replacements.
Understanding some math, especially geometry, is necessary for plumbers who must calculate exact angles for pipes and their fittings. The Pythagorean theorem is used in plumbing to find the value for true offset. The theorem holds that in a right triangle, the square of the side opposite the right angle equals the sum of the squares of the other two sides.Learn more about Plumbing
To solder copper pipe, polish the joining surfaces, apply the flux, heat the joint and apply solder. Each joint requires a few minutes to complete, but the time for the overall project depends on its complexity.Full Answer >
Pipe spools are sections of pipe that have been put together with fittings off-site to meet the needs of a construction project, according to the International Journal of Architecture, Engineering and Construction. Pipe spools increase the speed of construction.Full Answer >
Despite all the problems it can cause, a house's plumbing system works fairly simply. Hot and cold water come into the house under pressure through pipes and flow out of fixtures. Waste water and sewer gases exit through drains and vent stacks.Full Answer >
Plumbing is installed in a concrete slab before the concrete is poured. The lines actually rest in the dirt underneath the concrete. Repairing plumbing under concrete slabs is costly, so care must be taken in the installation to avoid problems.Full Answer >
