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
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 >

Push-fit plumbing uses specially designed valves, couplings, connectors and other pipe fixtures to join pipes without using clamps, glue, soldering or unions. A push-fit connector uses metal teeth to grip an inserted pipe and forms a watertight seal with a compression fitting O-ring once the pipe hits the tube stopper.Full Answer >
