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.
We donât really call it glue, but solvent-cement. None of the plumbing cements are interchangeable, each one is specific for its pipe. Each pipe is joined with its own cement. One exception is transition cement, used to weld ABS pipe and PVC pipe together.This transition cement is green in color so it's easy to recognize. The other exception is all-purpose cement which can be used to join any of the three pipes to each other.ll other uses of PVC, like irrigation, require primer regardless of the cement used. CPVC and ABS pipes don't require a primer. According to the folks at Oatey, CPVC cement may be used without primer where local codes permit. This tells me that the priming of CPVC is not necessary.
