Plumbright Endfeed One End Branch Reduced Tee - 42 x 42 x 35mm

An End Feed fitting is designed to be joined using solder and heat. The pipe inserts into the fitting socket, and solder is applied to create a permanent, sealed connection.

A Reduced Tee has two main run connections (42mm in this case) and one branch connection that is a different size (35mm). This allows you to connect a smaller diameter pipe off a larger one.

This fitting is rated for standard domestic hot and cold water systems and low-pressure gas. It is not designed for high-pressure industrial or commercial applications.

The fitting has Kitemark and WRAS certifications, indicating it meets stringent quality and safety standards for use in plumbing applications.

You will need a blowtorch (propane or butane), solder wire, flux, pipe cutter, and emery cloth or pipe cleaning tools.

Thorough cleaning of the pipe and fitting, proper application of flux, even heating of the fitting, and allowing the solder to be drawn into the joint by capillary action are key to a good joint.

While copper is durable, for buried applications, it is recommended to protect the pipework from potential ground contaminants or to use specific types of protective sleeving, depending on local regulations and ground conditions.

Ensure the pipe and fitting are thoroughly cleaned and fluxed. Check that sufficient heat is being applied to the fitting body itself. The fitting must be hotter than the solder for it to be drawn in.

The joint may not have been heated evenly, or the solder may not have fully penetrated. The joint will need to be heated again, ensuring proper flow. If the leak is significant, the joint may need to be redone entirely.

This is likely due to oxidation during heating. While cosmetic, ensure excessive oxidation does not impede solder flow. Clean off any heavy soot or scale after cooling.
