Domestic water safety valve
Attention

: domestic water safety valve with integrated check valve is obligatory safety regulation.

In HIU Stockholm this valve is integrated into pre-mounting unit (Position 1). If pre-mounting unit is
not included into delivery, domestic water safety valve with integrated check valve has to be
installed separately (order number: 1

4023

44) in pipeline as shown on picture above (Position 2).
