It will also be able to check the efficiency of underfloor heating and water meter.
As a result, the entire network plumbing and home heating will be able to work without complaint.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.
