Viega 20663 – Frequently Asked Questions
1) What size copper pipe does the Viega 20663 ProPress 45 degree elbow fit?
The Viega 20663 is a 4 inch by 4 inch elbow, so both ends take 4 inch copper tube. Both ends are press connections (P1 x P2), meaning there is no sweating or threading on either side.
2) Can I use a ProPress 45 degree copper elbow on a potable water line and on hydronic heating?
The 20663 is a copper press elbow for copper tube systems, which is the standard material for both potable water distribution and hydronic piping. The fitting body is copper, so it keeps the run in a single material and avoids dissimilar metal joints.
3) What does Smart Connect on the Viega 20663 actually do for me in the field?
Smart Connect is Viega's feature that intentionally leaks at an unpressed joint during pressure testing, so an elbow you missed shows itself before the ceiling closes up. On a 4 inch line with limited access that matters more than on small tube, since an unpressed 4 inch joint is a serious failure.
4) Should I use a 45 degree elbow or two 90s to offset a 4 inch copper riser?
A pair of 45s, like the 20663, gives a shallower offset with less pressure drop and turbulence than two 90 degree elbows, which is why 45s are the usual choice for jogging around an obstruction or swinging a branch off a main. Use 90s where you need a hard direction change in tight space.
