Potable water systems

Assuring optimum water quality

Water is our most precious asset, the vital element in sustaining life, and essential to most manufacturing processes. Helping to assure the quality of this vital element and supplying it in accordance with flawless hygiene standards is Viega’s core competency. 

Maximum hygiene in operation 

Potable water systems must be operated in line with their intended use. This includes ensuring water exchange at least every seven days. Suitable components prevent stagnation-related contamination in pipes through regular water exchange. 

Maximum economic efficiency 

Viega's Sanpress Inox stainless steel system provides an effective solution every time. What's more, the Easytop sampling valve is suitable for universal application, ensuring a high level of economic efficiency.

Maximum operational reliability and long-term safety 

The wide range of operating conditions in industrial plants means that the system and sealing elements have to be chosen carefully to ensure maximum operational reliability and long-term safety in practical application.

Potable water hygiene 

It is essential to focus firmly on hygiene when operating potable water installations. Selecting the right materials is equally important. The Viega Sanpress Inox stainless steel system always provides the right solution.

Testing potable water hygiene

One of the strong points of the Easytop extraction valve: It allows you to take water samples under conditions comparable to those used in a laboratory. Thanks to the two-piece system consisting of a stainless steel extraction valve and the universal gunmetal actuation unit, it is particularly economical because the actuation unit can be used at a large number of draw-off points.


The Easytop sampling valve 

  • Since the actuation unit is removable, it can easily be cleaned in an autoclave and furthermore effectively protects the system from water theft and manipulation
  • The valve body and outlet pipe rotate 360°, and the actuation unit can be installed in 45° increments. That ensures vertical orientation for sample-taking
  • The sampling valve can be chemically and thermally disinfected

For hygienic installations in areas where interruptions in use are envisaged, it is advisable to install suitable components for regular water exchange.
