Viega 77422 – Frequently Asked Questions
1) What pipe sizes does the Viega 77422 ProPress tee connect?
The Viega 77422 is a reducing copper press tee sized 1 inch x 3/4 inch x 3/4 inch. The run is 1 inch on one end and 3/4 inch on the other, with a 3/4 inch branch, so it steps a 1 inch copper main down to 3/4 inch while taking a 3/4 inch takeoff for a fixture group or riser.
2) Will the Viega 77422 press tee work on hard drawn type L copper tube?
Yes. It is a copper press fitting sized to nominal copper tube, so it presses onto standard rigid copper water tube in 1 inch and 3/4 inch. What matters more than the tube temper is prep: cut square, deburr, mark the insertion depth, and make sure the tube is fully bottomed in the cup before you press.
3) What does Smart Connect do on this Viega tee, and does it mean I can skip pressure testing?
Smart Connect is a feature of the sealing element that lets an unpressed connection leak intentionally during pressure testing, so a missed joint shows itself instead of hiding inside a wall. It is a detection aid, not a substitute for the test. You still pressure test the system to find the joints it flags.
4) How much clearance do I need to install the 77422 ProPress tee in a joist bay or stud wall?
Plan around the fitting envelope: 3.701 inches across, 2.398 inches high and 1.5 inches deep. The press tool jaw needs room to open and rotate around each cup beyond that, so in tight bays set the tee before closing the cavity and keep at least a jaw width of open space on the branch side.
5) Should I use a reducing press tee like this or a full size 1 inch tee with a reducer coupling?
A single 1 x 3/4 x 3/4 reducing tee gives you one fitting and three presses instead of a full size tee plus two reducers and the extra presses and length that come with them. That matters where you are branching off a 1 inch main inside a joist bay or a wall and have no room for a stacked assembly. Use a full size tee only when you actually need 1 inch continuing on both the run and the branch.
6) Is the Viega 77422 ProPress tee copper or bronze, and does that matter for a copper potable water system?
It is a copper fitting, which keeps a copper potable water line in the same base metal through the branch and avoids introducing a dissimilar metal at the joint. For the same reason it is the match for copper tube distribution rather than a brass or bronze transition body.
