Understanding the Principles behind Water Tapping

November 26, 2020

Normally, water main pipes provide municipal district lines with a huge amount of pressurised water. And as this pressurised water reaches different buildings and houses, these properties can subsequently enjoy the benefits of having water access to their taps and showerheads.

Installing a tapping fitting or a specialised piece of apparatus into an existing water main pipes can be done in two ways. The conventional way of this specific installation is by shutting the whole water system, which was deemed to be time-consuming and is not beneficial for property owners. Fortunately, the alternative way of installing a tapping fitting is through the process of water tapping.

Importance of Water Tapping

Water tapping is basically done to install and pierce a specialised piece of apparatus to the mains line without creating any issue or problem on the system. The purpose of the tapping fitting installation is to work effectively with a valve in controlling the water at a specific line. Once the drill used for the installation is removed and the valve is closed, the mains line can now prevent any leakage of water.

The whole process must be done carefully since the municipal district lines often receive more than 800 kPa of pressured water. Any mishaps along these lines can be catastrophic for properties and the communities that live around them. With hydraulic engineering, the water tapping process can be conducted easily without turning off the water supply and causing danger to communities.

The Water Tapping Process

The water tapping process usually starts by marking the utility lines and crosschecking them with existing municipal plans. Once the lines are identified, a digger or backhoe is then used to excavate the ground and expose the mains pipe. When the pipes are now exposed, the tapping fitting will be installed by clamping it carefully to the pipe. 

The tapping fitting is designed to girdle and strap the full circumference of the pipes. A corporation stopper or special stop valve is subsequently installed to work seamlessly with the tapping fitting. After they are fitted nicely, a tapping machine with a cutting head will be installed and operated so it can cut through the mains. Afterwards, the tapping machine, valve, and fitting will then be fitted securely to prevent losing water pressure. By the time the cutting process is done, the cutting head will be removed into the tapping machine while the valve will be closed, which only leaves a functional valve and tap.

Additional testing and boil orders, which are both required with conventional tapping fitting installation, are not needed with the modern form of water tapping.
