The domestic water station BWT DIAGO HWS-A
is a combination of valves and installations con-
taining in series (according to DIN EN 1988–200) a
non-return valve, backwashing filter and pressure
reducing valve. The non-return valve prevents wa-
ter from being sucked back out of the domestic
water installation into the piping network.
This filter is intended for the filtration of drinking
and service water. It protects the water pipes and
the connected water system parts from malfunc-
tions and corrosion damage due to impurities
such as rust particles, chippings, sand, hemp, etc.
