 PLUMBING TOOLS AND EQUIPMENTS
TYPES OF PLUMBING TOOLS
• Plumbing tools for pipe work
• Plumber's wrenches
• Drain cleaning tools for plumbers
• Safety tools for plumbers

1) PLUMBING TOOLS FOR PIPE WORKS

A. HACKSAW
 Plumbers commonly use hacksaws to cut perfectly in the pipe, and sometimes electricians to
cut conduit. Plumbers typically carry hacksaws so that they can cut through a variety of
items, including nuts, bolts, pipes, and screws.

B. HOLESAW
 A hole saw is also a useful addition to the toolkit that is needed in some cases. With the help
of a hole saw, it is possible to cut perfectly round holes in a variety of different materials. If a
hole is needed for a drainage or waste pipe, a hole saw can be used to cut the hole to the
exact size with a minimum of effort.

C. MOLE GRIPS
 These are the types of metal pliers characterized by the ability to be locked in place. It is
usually made of hardened steel. The upper jaw and handle are fixed, while the lower handle
and jaw are adjustable.
 It is primarily used to hold metal parts in place during welding, similar to when a plumber is
using a plumber’s torch to solder and seal the copper pipe.
D. TUBING CUTTER
 Tube cutter and pipe cutter are often used interchangeably on tube and pipe. Plumbers use
tubing cutters to cut through plastic tubing, with each of them having a different cutting
range, which is why they are so useful.

E. PLUMBER’S TORCH
 Plumber torches are the most common type used by professionals and DIY homeowners. The
plumber’s torch is a small, hand-held tool that allows plumbers to apply intense heat in the
most precise areas to solder and seal new piping for the purpose of installing and replacing it.

F. THREAD SEALING TAPE

 Thread seal tape is a versatile film tape used by most plumbers, usually a joint sealer to seal
pipe threads. Sometimes it is used as a leak preventer.
 This type of device is also known as Teflon tape, plumber’s tape, or polytetrafluoroethylene
film, abbreviated as PTFE tape.

G. PLIERS
 Plumbers also use pliers every day. It is best for plumbers to use these smaller tools for
loosening and tightening nuts and bolts that are too small to grasp with a wrench. The pliers
fit easily in a plumber’s hand to squeeze into tight spaces where a wrench won’t work.
 H. RATCHETING PIPE THREADER
 The ratcheting pipe threader tool allows you to cut threads into the pipe so that it will accept
the fitting when the pipes are joined together.

2) PLUMBER’S WRENCHES
 it is the most closely associated with plumbing, and no list of plumbing tools would be complete
without it. There isn’t a wrench that works as all-purpose. That’s why having some type of wrench
in your toolbox is essential

a. ADJUSTABLE WRENCH
 Also known as an adjustable pipe or “Stillson”, the wrench is used to grip or bend pipe or
circular bars. The work of tightening and loosening hexagonal nuts and fittings on pipes can
be easily done using this wrench. They are available in a variety of sizes, but plumbers often
have the 6- and 10-inch versions as they consider them perfect.

b. PIPE WRENCH
 The pipe wrench operates as the plumber’s most enormous wrench. These wrenches are good
for tightening and loosening nuts and fittings on pipes.
c. BASIN WRENCH
 This plumbing tool is used for turning fasteners in tight spaces that would be hard or
impossible to reach with a plumber’s wrench. These types of wrenches are also known as
sink wrenches.

d. TORQUE WRENCH
 a torque wrench is a tool that is used to tighten nuts and bolts according to a predetermined
torque value. This makes it possible to tighten the fasteners to the correct tension, preventing
damage from over-tightening or stripping the joints.

e. FAUCET KEY
 Not exactly a traditional wrench, but an essential item on any list of plumbing tools. Small,
X-shaped tools called faucet keys are used for opening and closing spigots and sillcocks. For
dealing with various stem fittings, such as 14", 9/32", 5/16", and others, there are adaptable
models on the market.

f. INTERNAL PIPE WRENCH

 The plumber uses an internal pipe wrench to remove pipe plugs, fittings, small nipples, and
broken threaded ends. In addition, it can also be useful for removing old rusted fittings on
 galvanized pipes. These tools hold a pipe or fitting's interior. Each wrench has markings for
different pipe sizes and can be used with a hex body.

3) DRAIN CLEANING TOOLS

Plumbers routinely clean drains because sometimes the issue isn’t with the pipe, but with what’s
located inside. Good plumbers are familiar with how to get rid of a tough clog and which tools
they’ll need to keep.

a. PLUNGERS
 The most common plumbing tool in a plumber’s toolbox is the plunger. Sink and toilet
plungers are commonly owned by homeowners, but plumbers should also carry them. It is
mainly used to clear blockages in drains or pipes commonly used in household toilets.

b. HAND AUGERS
 It is used to clear clogs from the drain lines and is also referred to as a plumber’s snake, drain
snake, or toilet jack. The hand auger consists of a long, flexible metal wire with a corkscrew
auger attached to the end.

c. HYDRO JETTING MACHINE

  It is a very efficient way to clean out sewer and drain lines. The first method for unclogging
blocked lines is usually hydro jetting, which uses high-speed or high-pressure water to clear
obstructions in pipe systems. These tools come with hose attachments that will blast water
into drain lines and sewer lines.

d. SNAKE MACHINE
 A snake machine is simply a bigger and updated version of a hand auger. Snake machines
typically have the strength to clear clogs that are particularly deep or challenging to move.
Also known as a plumber's snake or drain snake, it is often reserved for tough blockages that
cannot be loosened with a plunger.

e. DRAIN INSPECTION CAMERA

 also called borescopes, which used to be considered top technology in the plumbing trade.
These tiny cameras attached to a long, flexible cable are inserted deep into drains and sewer
lines.
 This gives a better look at the condition of the piping and whatever else may be obstructing it
4) Safety Tools for Plumbers

 Plumbers always get injured due to some incidents while on the job. Obviously, there are a
variety of tools that assist in protecting plumbers and significantly reduce the likelihood of an
accident.

a) Drain Cleaning Gloves

 Drain-cleaning gloves are one of the most common and essential plumbing tools, usually made from
leather, PVC (rubber), or synthetic materials. This is significant because plumbers frequently handle

materials that others would prefer to avoid touching with their bare hands.

b) Goggles

 They mainly protect the eyes from liquid or chemical splash, irritating mist, vapor, and smoke. When
working on a plumbing project, goggles shield your eyes from any potentially harmful materials you
come into contact with.
 Plumbers must carefully inspect leaks, soldering, and other things that may be hazardous to their eyes.
Therefore, it is pretty useful to have goggles in the toolbox.

c) Flashlights

 The majority of plumbers will find themselves having to go into dark spaces regularly, such as
basements, so it is always a good idea to have a flashlight handy.

d) Heat Shields or Pads

 Using the right safety equipment is essential if soldering is a regular part of your dayto-day activities.
This will protect both you and the homeowner. It's good to round out your plumbing tool list with
reliable heat shields and pads. When soldering is required.
