VIEGA reducing tee 22 x 22 x 18 mm (model 315030)

VIEGA reducing tee 22 x 22 x 18 mm is a metal plumbing fitting designed to form a branch from a 22 mm pipe run while stepping down to an 18 mm connection. The fitting provides a compact and robust junction for potable water and heating systems where reliable, leak-tight joints and matched connection sizes are required. Constructed to integrate with common press or solder connections used in residential and commercial plumbing, this reducing tee supports straightforward installation and stable flow distribution between different pipe diameters.

Advantages

The reducing tee combines a durable metal construction with precise dimensional tolerances to ensure consistent fit and long service life. Its stepped design allows a smooth transition between 22 mm and 18 mm piping, minimising turbulence and pressure drop at the branch. The component is compatible with common installation techniques and materials used in domestic and commercial potable water and heating systems, enabling reliable joints and reduced risk of leakage when installed according to manufacturer guidelines.

Suitable for

• Creating a branch in potable water distribution systems
• Branching off heating system pipe runs
• Connecting pipes of different diameters in domestic plumbing
• Commercial installations requiring compact reduction fittings

Key specifications

• Main connection diameter: 22 mm
• Branch connection diameter: 18 mm
• Material: metal plumbing fitting suitable for potable water and heating
• Function: reducing tee for creating a branch and reducing pipe size
• Typical installation methods: compatible with common press or solder connections (system-dependent)

How to use

Position the reducing tee at the intended branch point on the 22 mm run and prepare pipe ends according to the chosen joining method (cleaning, deburring, and applying required flux or press sleeves as applicable). Insert the 22 mm pipes into the main ends and the 18 mm pipe into the branch end, ensuring full engagement and correct alignment. Complete the joint using the appropriate technique specified for the piping system in use (pressing, soldering, or brazing) and verify each connection for tightness. Follow local codes and installation instructions for potable water and heating systems to ensure safe and compliant operation.

Usage recommendations

Use matching fittings and installation tools recommended for the pipe material and joining method. Inspect joints after installation and pressure-test the system where required. For potable water installations, follow applicable standards and use approved materials and procedures to maintain water quality.
