Water service connections link properties to the water distribution main.
The work involves tapping a live water main under pressure, typically 1 to 8 bar.
Operatives must be competent and hold appropriate water industry qualifications.
The connection must use approved fittings and methods specified by the water company.
Excavation near the main requires service detection and hand digging.
Contamination of drinking water is a serious public health risk during connection.
Hygiene protocols must be strictly followed — fittings and pipe must be disinfected.
The Water Supply (Water Fittings) Regulations 1999 set legal requirements.
Pressure testing and chlorination must be completed before commissioning.
Failed connections cause uncontrolled flooding that can undermine roads.

Public health	Contaminated water supplies cause disease outbreaks affecting communities.
Flooding risk	Failed live tapping causes high-pressure water release flooding the area.
Legal compliance	Water Fittings Regulations require approved materials and competent installers.
Operative safety	Pressurised mains create risks of pipe whip and water jet injury.
