1 NGfL CYMRU GCaD PLUMBING TOOLS

2 NGfL CYMRU GCaD Blow torches are used to heat metal during soldering. Gas can be supplied via a portable, reusable gas bottle. PLUMBING TOOLS

3 NGfL CYMRU GCaD Above: portable blow torch with disposable gas cylinder. PLUMBING TOOLS

4 NGfL CYMRU GCaD Flux is applied to prevent oxidisation of the surfaces of connectors. PLUMBING TOOLS

5 NGfL CYMRU GCaD Pipe work is heated using a blow lamp. Solder is melted to a liquid with the blow lamp, and is used to weld connectors and pipes together. Once cooled, the solder returns to a solid, forming a watertight seal. PLUMBING TOOLS

6 NGfL CYMRU GCaD Left: oxy-acetylene bottles. One bottle contains oxygen, the other contains acetylene, which is a fuel source. The gasses inside the cylinders are compressed and are in liquid form: once the gasses leave the cylinder, they become gas and are mixed to form a flammable mixture. PLUMBING TOOLS

7 NGfL CYMRU GCaD THE FIRE TRIANGLE HEAT OXYGEN FUEL In order for anything to burn, 3 elements, as above, need to be in place. Oxy-acetylene welding & burning provides these elements. PLUMBING TOOLS

8 NGfL CYMRU GCaD Top left: oxy-acetylene torch just after ignition: bottom left: torch at full temperature. Below: welding lead using oxy-acetylene torch. PLUMBING TOOLS

9 NGfL CYMRU GCaD Pipes are bent to shape using pipe bending tools. The series of images shown next show pipe being bent. PLUMBING TOOLS

11 NGfL CYMRU GCaD PLUMBING TOOLS

12 NGfL CYMRU GCaD Above: a selection of tools commonly used in plumbing. These are labelled on the following slide. PLUMBING TOOLS

13 NGfL CYMRU GCaD Gas Bottles Dust Pan & Brush Junior Hacksaw Hacksaw Plumb / string line Grips PLUMBING TOOLS

14 NGfL CYMRU GCaD Adjustable spanner being used to tighten a radiator valve. PLUMBING TOOLS

15 NGfL CYMRU GCaD Grips being used to tighten a sink waste pipe. PLUMBING TOOLS

16 NGfL CYMRU GCaD A weir flow gauge is used to determine the rate of water flow. PLUMBING TOOLS

17 NGfL CYMRU GCaD Hammer. PLUMBING TOOLS

18 NGfL CYMRU GCaD Above: slotted screwdriver. Below: Phillips screwdriver PLUMBING TOOLS

19 NGfL CYMRU GCaD Differential temperature gauge, used to measure difference in temperature between the flow and return of a combination boiler. PLUMBING TOOLS

20 NGfL CYMRU GCaD A manometer, used to measure pressure. PLUMBING TOOLS

21 NGfL CYMRU GCaD Test & training mock up of a typical domestic hot water system. PLUMBING TOOLS
