Return loss is the negative of the magnitude of the reflection coefficient in dB. Since power is proportional to the square of the voltage, return loss is given by, where the vertical bars indicate magnitude.eturn loss is the negative of the magnitude of the reflection coefficient in dB.

Welcome. Why Repipe, When you can ePIPE! ePIPE provides a solution for plumbing system failures such as pinhole leaks and slab leaks, corrosion control, low water flow, and lead/copper contaminants. ePIPE is an affordable, effective, and less disruptive alternative to an ordinary re-pipe.
For a reliable seal, you have to use the solvent that's formulated for the pipe. All of them contain aggressive solvents and adhesives, so beware of drips and spills. There are three common types of plastic plumbing pipe: PVC, CPVC and ABS. Each requires a different kind of solvent cement. The white or beige pipes (PVC and CPVC) also require a primer. You don't need a primer with black ABS pipe. Read the label to match the solvent cement to the type of pipe you're using.
