Viega 25945 – Frequently Asked Questions
1) What sizes does the Viega MegaPress 25945 reducing tee connect?
The Viega 25945 is a reducing MegaPress tee sized 1-1/4 inch by 3/4 inch, so the run is 1-1/4 inch and the reduced branch takes 3/4 inch. Both ends are press connections (P1 x P2), not threaded or grooved.
2) Can I press the Viega 25945 onto copper or PEX?
No. The 25945 is carbon steel and MegaPress fittings press onto black iron pipe, so it is the wrong fitting for copper tube or PEX. For a copper line you want a ProPress copper fitting instead; a carbon steel fitting on copper is a dissimilar metal joint you do not want in a water system.
3) Do I need to thread or weld the branch when I tap a 3/4 inch line off a 1-1/4 inch steel main?
Not with this fitting. The 25945 presses onto cut and deburred black iron pipe on all three ends, so a 3/4 inch takeoff from a 1-1/4 inch main is made cold with a press tool. No threading, no cutting oil, no hot work permit, which is why it gets used in occupied buildings.
4) Does the MegaPress 25945 need to be pressed with a specific jaw size?
Yes, and it needs two. The 1-1/4 inch run and the 3/4 inch branch are different press sizes, so you press the large ends with the 1-1/4 inch MegaPress jaw or ring and the branch with the 3/4 inch jaw. One jaw will not finish the fitting.
5) How much room do I need around the Viega 25945 tee to make the press?
The fitting body itself is 4.374 inches long and 2.205 inches in both height and width, and it weighs 0.734 lbs. Add clearance beyond that for the press tool jaw to seat square on each connection, which is usually what decides whether you can press in a tight joist bay or against a wall.
6) What does Smart Connect do on this MegaPress reducing tee?
Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks deliberately during pressure testing so the installer can find the joint they missed before the system is closed up. On a reducing tee like the 25945, with three connections at two different sizes, that is the practical safeguard against leaving the small branch unpressed.
7) Is the Viega 25945 the same as the galvanized MegaPress fitting?
No. The 25945 is plain carbon steel, which is what you run on black iron pipe systems. If the existing pipe is galvanized, Viega's MegaPressG line is the one specified for that service. Matching the fitting material to the pipe matters more on steel than on copper.
