Viega 25405 – Frequently Asked Questions
1) What are the three outlet sizes and connection types on the Viega MegaPress 25405 tee?
The Viega 25405 MegaPress tee is a 3/4 inch x 3/4 inch x 1/2 inch reducing tee with a P1 x P2 x FPT connection pattern. The two 3/4 inch run ends are press connections onto carbon steel pipe, and the 1/2 inch branch is a female pipe thread. So you press the run into the line and thread the branch, which is what you want when you are picking up a gauge, a drain valve, a sensor well, or a threaded drop.
2) Can I use a MegaPress carbon steel tee on copper or PEX?
No. The 25405 is a carbon steel MegaPress fitting, and MegaPress press connections are made onto black iron/carbon steel pipe. For copper you need Viega's copper press line (ProPress), and for PEX you need a PEX system fitting. Putting a carbon steel press fitting on copper is the wrong material pairing and the wrong press profile.
3) What is Smart Connect on this Viega press tee and why does it matter on a punch list?
Smart Connect is the feature built into the 25405 MegaPress tee that lets an unpressed joint leak during pressure testing, so you find the connection you skipped before the system goes into service instead of after the ceiling is closed. On a large press job that is the difference between a five minute fix and a callback.
4) Should I use a press tee with a threaded branch or an all press tee?
Use the FPT branch version, like the 25405, when the takeoff has to accept a threaded device: a pressure gauge, relief valve, sensor, nipple, or a transition to another piping material. Use an all press tee when the branch just continues in carbon steel pipe, because every threaded joint is one more place to dope, wrench and leak-check. Here the run stays press on both 3/4 inch ends and only the 1/2 inch branch is threaded.
