Viega 77447 – Frequently Asked Questions
1) What size copper pipe does the Viega 77447 ProPress tee connect?
The 77447 is a reducing press tee sized 1-1/4 inch x 1-1/4 inch x 1 inch. Both run ends take 1-1/4 inch copper tube and the branch takes 1 inch, so it drops a 1 inch branch line off a 1-1/4 inch main without needing a separate bushing.
2) Is the Viega 77447 tee solder or press fit?
Press fit, no flame. All three ends are press connections (P1 x P2 x P3), so the tee is joined with a ProPress tool and jaws rather than soldered. That makes it usable in occupied buildings and tight ceiling cavities where a torch and a hot work permit are a problem.
3) What does Smart Connect technology do on a Viega ProPress fitting?
Smart Connect is the feature that makes an unpressed fitting leak on purpose during test. If the 77447 gets missed on a run, water or air passes at the unpressed connection so the installer finds it at pressure test instead of after the ceiling is closed. It does not change how the fitting is pressed.
4) Is this Viega tee copper or bronze, and can I use it on a copper potable water line?
The 77447 is a copper press tee, so it is the same base metal as the copper tube it joins on a potable or hydronic copper system. No dissimilar metal transition is introduced at the tee.
5) How much room do I need to fit a 1-1/4 x 1-1/4 x 1 ProPress tee in a joist bay?
The fitting body measures 3.819 inches wide, 2.677 inches high and 1.76 inches long, and weighs 0.545 lbs. Those are the fitting dimensions only, so add clearance for the press jaw around each of the three ends when you are laying out a tight bay or a stacked wall.
6) Do I need a reducer bushing to run a 1 inch branch off 1-1/4 inch copper with this tee?
No. The reduction is built into the 77447, with 1-1/4 inch on both run ends and 1 inch on the branch. One press at each of the three ends finishes the joint, which is one less connection to leak than a full-size tee plus a reducer.
