Viega 20818 – Frequently Asked Questions
1) What size pipe does the Viega 20818 ProPress reducer connect?
The Viega 20818 is a 3 inch by 1-1/2 inch copper reducer, so it steps a 3 inch copper line down to 1-1/2 inch in one fitting. The connection arrangement is FTG x P: the 3 inch end is a fitting-end (FTG) that slips into the socket of another 3 inch fitting or a 3 inch press coupling, while the 1-1/2 inch end is a press socket that takes 1-1/2 inch copper tube. Get that orientation right before you cut, because an FTG end will not accept tube.
2) Does the 3 inch end of the Viega 20818 reducer slip over the pipe or into a fitting?
Into a fitting. FTG means the 3 inch end is sized like copper tube itself, so it drops into the press socket of another 3 inch ProPress fitting rather than receiving pipe. If you need a reducer that presses onto a 3 inch tube stub, an FTG end is the wrong choice and you want a P x P reducer instead. The small side of the 20818 is a P (press) socket, so 1-1/2 inch copper tube goes into that end.
3) Can I use a copper ProPress reducer on steel or PEX lines?
No. The 20818 reducer is copper and its press ends are made for copper tube. Copper press fittings are matched to copper tube dimensions and sealing elements; carbon steel and stainless systems use their own fitting lines, and PEX uses a different connection entirely. Keep the copper reducer on copper.
4) Is the Viega 20818 reducer a soldered fitting or a press fitting?
Press. Both ends of the 20818 are made up cold with a press tool, no torch, no flux, no solder. That is the reason it gets specified on occupied buildings, hospitals and hotels where a hot work permit or a fire watch would otherwise be required to change out a section of copper.
5) What does Smart Connect mean on a Viega ProPress fitting?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks visibly during pressure testing so the installer finds it before the wall closes. On a 3 x 1-1/2 reducer buried in a chase, that is the difference between a callback and a five minute fix at test.
6) What part number do I order for a Viega 3 inch x 1-1/2 inch copper ProPress reducer?
Order Viega 20818. That is the manufacturer part number for the 3 inch by 1-1/2 inch copper ProPress reducer in FTG x P, and the fitting is made in Germany. It is a single configuration, so there is no finish or option to specify on the order.
7) How heavy is a 3 x 1-1/2 ProPress copper reducer for overhead support spacing?
The 20818 weighs 1.157 pounds. Light enough that the fitting itself is not the load on an overhead run, but on a 3 inch copper main the transition point is still worth hanging close to, since the reducer is where the pipe changes diameter and the support spacing changes with it.
