Plumber Math: Offsets Part 3 - Rolling Offsets Using 45 Degree Fittings

A truly professional plumbers is going to know how to calculate a rolling offset. Being able to calculate for a rolling offset is often required on journeyman or master plumber tests as well. Without calculating, a plumber might eyeball or make a guess at how long the pipe should be, but this often results in material expenses as the pipe will be too long or too short and will have to be cut again. There are a few steps involved with calculating a rolling offset. The math is based on the Pythagorean theorem. A rolling offset actually involves two triangles. First there is the triangle created by the offset and the rise. Then the diagonal of that triangle is used to find the diagonal where the pipe will go. In this video Plumber-Tom explains and demonstrates how to calculate a rolling offset.
