Who invented feed water systems. What is the origin of feed water systems?
Use water for testing.
As per the Italian standard, the standard height of the wall hung water closet is 420mm, Table top basin is 850mm
What would you like to know about them? I have an e-book here " understanding hot water heating systems" http://www.amazon.com/Understanding-Water-Heating-Systems-ebook/dp/B007IVVK4O Hope that helps.
There are many types of 'systems' in a system engineer job. Some tasks of those systems are working on telephone systems, water systems, food distribution networks, and sewage systems.
NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems
To perform a soundness test on hot and cold water systems, you should pressurize the system to the recommended level and check for any leaks, using soapy water to detect escaping air bubbles. Inspect all joints, fittings, and connections for signs of leaks. Make sure all components are securely fastened and there are no visible signs of damage or deterioration.
Drinking the water and if it is possible comparing the taste with the taste of a standard water (organoleptic testing).
To test the soundness of hot and cold water systems, you can check for leaks or drips in the pipes, inspect for any unusual noises or vibrations, verify appropriate water pressure levels, and ensure that the water is reaching the desired temperature at each outlet. Running a flow test and monitoring for any inconsistencies in water quality can also help identify potential issues in the system.
The standard water supply line sizes used in residential plumbing systems are typically 1/2 inch or 3/4 inch in diameter.

There are several NFPA standards that reference fire hydrant requirements, for various parameters, including NFPA 1 Fire Code and NFPA 101 Life Safety Code. You may also be interested in NFPA 291 Recommended Practice for Fire Flow Testing and Marking of Hydrants NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems or NFPA 1142 Standard on Water Supplies for Suburban and Rural Fire Fighting
The water supplier can provide you the details on hardness level if you are on municipal water systems, If you are using private water then you can get tested in laboratories. You can even measure it with water hardness testing kits which you need to purchase.
NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems contains requirements for FDC signage (e.g. 4.8 and 13.7.1), for all water-based systems. Each individual standard for the specific type of system (sprinkler, standpipe, etc), there are specifications for signage. For example, NFPA 13: 8.17.2.4.7 "Signs" specifies the signs required for an FDC servicing a sprinkler riser, including height of lettering and required legends.
To carry out a soundness test on a cold water system, you would typically isolate the system, fill it with water, and then pressurize it to a specific level using a pump. The system is then left under pressure for a designated time to observe if there are any leaks. If the pressure remains consistent, it indicates that the system is sound.
