‘Solder’ means to connect plumbing joints and pipework together to maintain the watertight integrity of appliances. This is done by melting a soft metal solder over the joint, with a direct heat source like that of a blowlamp. As long as the process is done correctly, these joints will be really watertight and permanent. Greenford Plumbers can use both types of soldering

Fittings:

1). Solder Ring Fittings (has integral ring of solder).
2). End feed fittings (comes off a reel).

Method:
Each surface to be soldered that touches needs to be clean, both inside and out with wire wool or similar. Spread flux on the clean surfaces. This flux is a special type of paste, and can be found in plumber’s merchants. The flux is applied to keep the areas clean whilst soldering, it also ensures the hot molten solder sticks to the copper and flows much easier. Make sure the pipework that is going to be soldered has no water in it because this will have a cooling affect that could slow or stop the soldering process as the solder will not melt completely or flow correctly. A professional plumber like a Greenford Plumber is qualified to solder all types of pipe joints. Apply direct heat from the blowtorch to the joint and let the solder melt. Solder must be worked as soon as it melts so it will not burn the flux off. Soldered fittings can be used in which case the solder will run from the mouth of the fitting. You should take care regarding combustible materials near the heat source as it could quite easily cause a fire. Allow the joint to cool totally after soldering so it will be a good fit.

NOTE:
Remove the residual flux off from the pipework once the soldering is finished, or the pipe may corrode. Check for leaks. For hot and cold water supplies use Lead Free solder.”
