Study these words before doing the exercises.
torque wrench
a wrench that tightens fittings to a precise level of force to prevent over-tightening
"Use the torque wrench to tighten the compression fitting to the correct specification."
pipe bender
a tool used to bend metal pipe to a specific angle without collapsing it
"Use the pipe bender to form a ninety-degree bend in the copper."
inspection camera
a small flexible camera used to look inside pipes and drains
"Feed the inspection camera into the drain to locate the blockage."
deburring tool
a tool used to remove sharp edges from the inside of a cut pipe
"Run the deburring tool around the inside edge before fitting the joint."
flux brush
a small brush used to apply flux evenly to copper pipe before soldering
"Apply flux with the flux brush to every joint surface."
compression tester
a device used to check that pressure inside a system holds steady after a repair
"Run the compression tester across all joints before signing off the job."
pipe freezing kit
a kit that freezes water in a pipe section to create a temporary block
"Use the pipe freezing kit so you can work on the joint without draining the system."
drain snake
a long flexible steel cable used to clear blockages deep inside a drain
"The plunger did not clear it. Try the drain snake."
multimeter
an electrical testing device used to measure voltage, current and resistance
"Check the pump connections with the multimeter before replacing it."
pressure relief valve
a safety valve that opens automatically to release excess pressure
"The pressure relief valve has activated. The system pressure is too high."
pipe lagging
insulating material wrapped around pipes to prevent heat loss or freezing
"Fit pipe lagging to all exposed pipework in the loft."
PTFE tape
a white thread seal tape used on threaded joints to prevent leaks
"Wrap PTFE tape clockwise around the thread before fitting the valve."
crimping tool
a tool used to join pipes with push-fit fittings by compressing a metal ring
"Use the crimping tool to secure the push-fit connection on the manifold."
hydraulic pump
a hand or powered pump used to pressurise a system for leak testing
"Attach the hydraulic pump and raise the pressure to six bar for the test."
isolation tool
a specialist tool used to close off a pipe at the stopcock without draining
"The isolation tool lets you work on the tap without turning off the main supply."
