Repair plumbing services performed in hospitals
To common plumbing services should be installation of new sanitary facilities and repair of these devices and mending other hydraulic faults. Frequently performed hydraulic services for apartments are repairing a leaky faucet or washing machines, which ceased to spin the laundry. Similar repairs are done at home.
But in such buildings often you have to also carry out work related to repair leaks resulting in the installation of plumbing.
This is because the state of the responsibility of owners of housing blocks and homes can have installations mounted a dozen years earlier.
Similar situation may occur also in the case of hospitals.
Tools for plumbing - Wikipedia
Plumbing equipment includes devices often hidden behind walls or in utility spaces which are not seen by the general public.
It includes water meters, pumps, expansion tanks, backflow preventers, water filters, UV sterilization lights, water softeners, water heaters, heat exchangers, gauges, and control systems.
Specialized plumbing tools include pipe wrenches, flaring pliers, pipe vise, pipe bending machine, pipe cutter, 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 video cameras for inspections of hidden leaks or problems, they use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.Źródło: https://en.wikipedia.org/wiki/Plumbing#Equipment_and_tools
Plumbing snakes - some types
Hand auger / hand spinner
Hand augers are useful for clearing sink and bathtub drains. They are unsuitable for sending through flush toilets, because the wire might damage the bowl; also, flush toilets have relatively large drain pipes in which the narrow snake can be become tangled.
(A 1?4-inch cable, for example, should never be used in a drain with a calibre of more than two inches.)
Closet auger / toilet auger
The closet auger (named after water closet) feeds a relatively short auger through a hook-shaped length of metal tubing.
The hook shape makes it easier to feed the auger into the toilet. A plastic boot on the end of the auger protects the finish of the visible porcelain.
Since most toilet clogs occur in the trap built into the bowl, the short cable is sufficient to break up or retrieve the greater majority of clogs.
