Calefactio’s service valve for potable water system combines many functions, one of which is offering the ability to read the system pressure at any time. When the valve is shut, it is possible to use it to drain the tank or to do its maintenance. Once the tank is drained, it is easy to check that its pressure is equal or higher than the municipal system and adjust it if it is not the case to ensure its proper functioning.
