Plumbing equipment includes devices often  behind walls or in utility spaces which are not seen by the general public. It includes [[water meter]]s, [[pump]]s, expansion tanks, [[back flow preventers]], [[water filter]]s, [[UV sterilization]] lights, [[water softener]]s, [[water heating|water heaters]], [[heat exchangers]], gauges, and control systems.

There are many tools a plumber needs to do a good plumbing job. While many simple plumbing tasks can be completed with a few common hand held tools, other more complex jobs require specialised tools, designed specifically to make the job easier.

Specialized plumbing tools include [[pipe wrench]]es, [[flaring pliers]], pipe vise, pipe bending machine, pipe cutter, [[Tap and die|dies]], and joining tools such as soldering torches and crimp tools. New tools have been developed to help plumbers fix problems more efficiently. For example, plumbers use [[CCTV drain camera (plumbing)|video cameras]] for inspections of hidden leaks or other problems; they also use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.

Flooding from excessive rain or clogged sewers may require specialized equipment, such as a heavy duty pumper truck designed to vacuum raw sewage.{{citation needed|date=May 2015}}
