Hot water storage safety group
A safety group combines several components with different functions in one device that is installed between the cold water network and the hot water storage tank. This essential safety device protects both the hot water system and users from potential hazards by providing pressure protection, backflow prevention, pressure relief, and system isolation capabilities.
As water temperature increases, pressure also increases inside the water tank due to water dilation, making pressure protection crucial. The safety group prevents contaminated water from flowing back into the clean water supply, automatically releases excess pressure to prevent tank damage or explosion, and allows for safe maintenance and servicing. Essential components include a safety valve for pressure relief, a backflow preventer or check valve, an optional shut-off valve, and sometimes a pressure gauge.
The unit should be installed as close as possible to the storage tank, with professional installation recommended to ensure proper operation and compliance with local plumbing codes. Safety groups are legally required in many jurisdictions and are critical for preventing dangerous pressure buildup, water contamination, and potential system failures in hot water storage systems.
