Viega 22278 – Frequently Asked Questions
1) What pipe sizes does the Viega 22278 ProPress tee connect?
The Viega 22278 is a reducing copper press tee sized 2-1/2 inch x 2 inch x 2 inch. The run takes 2-1/2 inch copper on one end, and both the opposite end and the branch take 2 inch copper. All three openings are press connections (P1 x P2 x P3), so no soldering.
2) Can I press a 2-1/2 inch Viega ProPress tee with my standard press tool jaws?
No. At 2-1/2 inch, the Viega 22278 is above the range of standard ProPress jaws. Fittings 2-1/2 inch and larger are pressed with a press ring and actuator rather than a jaw, so you need the XL-size ring for the 2-1/2 inch end plus jaws or rings for the 2 inch branch and outlet. Budget for both sizes before the fitting goes in the wall.
3) Do I need a separate reducer to branch down from 2-1/2 inch copper main to 2 inch?
Not with this fitting. The 22278 does the reduction inside the tee: 2-1/2 inch in on the run, 2 inch out on the run and 2 inch on the branch. One fitting, three presses, no bushings or reducing couplings to stack up.
4) What is Smart Connect on this Viega press tee and why does it matter on an inspection?
Smart Connect is a feature of the sealing element in the 22278 ProPress tee that intentionally leaks a small amount of water at an unpressed connection during pressure testing. On a large reducing tee like this one, with three separate presses to make, it is how you find the joint the crew missed before the system is charged and covered.
5) Is the Viega 22278 tee suitable for copper water lines only, or can I use it on steel pipe?
Copper only. The 22278 is a copper-body press fitting with copper press ends, so it goes on hard copper tube. Carbon steel or stainless systems need Viega's MegaPress or ProPress stainless lines instead, not this fitting.
6) How much clearance do I need around a 2-1/2 inch x 2 inch x 2 inch ProPress tee in a tight ceiling or chase?
The fitting itself measures 7.024 inches wide, 4.949 inches high and 3.177 inches long, and it weighs 1.84 lbs. Those are the body dimensions only; the press ring and actuator need considerably more room to swing, so lay out the branch with working clearance beyond the fitting footprint rather than to these numbers.
7) What part number should I order for a Viega 2-1/2 x 2 x 2 copper press tee?
Viega part number 22278. That is the manufacturer part number for the copper ProPress reducing tee in 2-1/2 inch x 2 inch x 2 inch, made in Germany.
8) Can a press tee like this be used on an existing wet system without draining it?
No. A press connection on the 22278 has to be made on clean, dry, deburred tube with the sealing element seated, so the line must be drained and the tube ends prepped before pressing. The advantage over sweating is that there's no flame and no hot work permit, not that you can press a live line.
