Viega 20858 – Frequently Asked Questions
1) What size pipe does the Viega 20858 ProPress adapter flange connect to?
The Viega 20858 is a 3 inch copper ProPress adapter flange. The press end takes 3 inch copper tube, and the flange face is the mating side that bolts to your valve, pump, or flanged equipment. It is a two-piece design, so the flange ring is separate from the pressed adapter body.
2) Is the Viega 20858 flange for copper tube or steel pipe?
Copper. The 20858 presses onto 3 inch copper tubing, not black or galvanized steel pipe. If the run is steel or stainless, you need the equivalent MegaPress or ProPress stainless flange instead, not this one.
3) Do I still need to solder or thread anything to install this Viega ProPress flange?
No torch and no threading. The 20858 is a press fitting: clean and mark the 3 inch copper tube, slide the fitting on, and press with a ProPress tool and the matching 3 inch jaw or ring and actuator. The bolted flange face handles the connection to the equipment, so the only field work on the pipe side is the press.
4) What is Smart Connect on the Viega 20858 and why does it matter on an inspection?
Smart Connect is Viega's unpressed-connection feature. If a fitting gets missed during install, the feature lets water pass at the joint during pressure testing so the unpressed connection shows itself rather than hiding behind a wall or in a ceiling. On a 3 inch line feeding a pump or riser, that is the difference between finding it at test and finding it after startup.
5) Is the Viega 20858 a two-piece flange, and does the ring rotate for bolt alignment?
It is a 2-piece flange. The press adapter and the flange ring are separate components, so the ring can be turned on the adapter to line the bolt holes up with the mating flange before you tighten. That is the main reason installers choose a two-piece over a one-piece flange on tight equipment connections.
6) Does a gasket and bolt set come with the Viega 20858 ProPress flange?
The 20858 is the adapter flange itself. Flange gaskets, bolts, nuts and washers for the bolted joint are supplied separately and should be ordered to match the mating flange you are landing on.
