Direction Of Flow - Kessel Staufix SWA Anleitung Für Einbau, Bedienung Und Wartung

The backwater needs to be checked every six
months at a minimum by a qualified and licen-
sed service technician. During the inspection
no wastewater should pass through the back-
water valve.
The following should take place during this ins-
pection:
① Any debris or build up should be removed
from the parts of the body (thorough clea-
ning)
② The condition of gaskets / seals and the
surfaces they come in contact with should
be inspected – if required the gasket / seal
should be replaced (see illustrations 7 to 9)
③ Check for proper movement of the two flaps
as well as the manual closure lever – lubri-
cate if necessary
④ Check to make sure the system is water
tight and in proper operating condition by
performing the function / sealing test (see
Chapter 3)
