Viega 79220 – Frequently Asked Questions
1) What do the two sizes on the Viega 79220 adapter mean, 1/2 inch and 3/4 inch?
The Viega 79220 is a 1/2 inch press by 3/4 inch male pipe thread adapter. The press end goes on 1/2 inch copper tube, and the threaded end is a 3/4 inch MPT that screws into a female thread. So it changes both the joining method and the size in one fitting.
2) Will the Viega 79220 press onto 1/2 inch copper pipe with a standard ProPress tool?
Yes. The press end is a 1/2 inch ProPress connection, so it presses with a ProPress tool and the 1/2 inch jaw or ring. No solder, no flame.
3) Can I use the 79220 to connect a copper line to a 3/4 inch FIP water heater or valve port?
That is the normal use. The 3/4 inch male thread screws into a 3/4 inch FIP port on a valve, tank, pump, or manifold, and the 1/2 inch press end takes the copper branch. Note the reduction: you are dropping from a 3/4 inch port to a 1/2 inch tube, so size the flow accordingly.
4) Is this ProPress adapter safe for potable drinking water lines?
The 79220 adapter is Zero Lead bronze, which is the material Viega supplies for potable water service. Same fitting works on hydronic heating and chilled water where bronze is acceptable.
5) What does Smart Connect do on this Viega adapter, and can I tell if I forgot to press it?
Smart Connect is the feature built into the 79220 press end: an unpressed connection intentionally leaks during pressure testing so you can find it before the wall closes up. It is a verification aid, not a substitute for pressing every joint.
6) What is the manufacturer part number for this Viega ProPress 1/2 x 3/4 adapter, and where is it made?
Order it as Viega part 79220. It is made in Germany.
