Viega 79715 – Frequently Asked Questions
1) What connection ends does the Viega 79715 ProPress union have?
The 79715 is a press by female pipe thread union, 1-1/4 inch on both ends. One side presses onto 1-1/4 inch copper or copper alloy tube with a ProPress tool, the other takes 1-1/4 inch male threaded pipe. So it is the fitting you use where a pressed copper run has to meet a threaded connection, like a pump, valve, or meter, and still come apart later.
2) Is the Viega 79715 union lead free for potable water?
It is a Zero Lead bronze union, which is what you want on potable water lines. The body material is bronze and Viega markets this line as Zero Lead.
3) What is Smart Connect on a Viega ProPress union and why does it matter on a punch list?
Smart Connect is Viega's feature that lets an unpressed connection leak during pressure testing so the installer finds it before the wall closes. On the 79715 union that means an unpressed 1-1/4 inch joint shows itself at test rather than after drywall. It does not change how the joint is made, only how a missed press gets caught.
4) How much space do I need to fit a 1-1/4 inch Viega 79715 union?
Plan for a fitting roughly 1.969 inches long, 1.693 inches wide, and 2.087 inches high, plus clearance for the press jaw to swing around the press end. In tight joist bays or against a wall, the jaw is what governs, not the fitting body.
5) Should I use a ProPress union or just a threaded union on a 1-1/4 inch copper line?
On copper, a press by FPT union like the 79715 saves you from having to solder or thread the tube side. You press the copper end cold and keep the threaded end for the serviceable joint at the equipment. A full threaded union would mean adapting the copper to thread first, which adds a joint and a heat step. Where both sides are already threaded steel pipe, the press end buys you nothing.
6) Does the Viega 79715 come apart for servicing equipment?
That is the point of it. A union has a nut that breaks the joint without cutting pipe, so the 1-1/4 inch connection at a pump, water heater, or backflow device can be opened and reassembled. The press side stays permanent on the copper.
7) Do I need a sealant on the threaded side of the Viega 79715 union?
The FPT side is a standard tapered female thread, so it takes thread sealant or PTFE tape on the mating male pipe like any threaded joint. The press side needs no sealant at all, it relies on the factory sealing element and a proper press with the correct 1-1/4 inch jaw.
