1. General
Dear Customer,
Before installing and commissioning this
KESSEL Staufix® SWA or Controfix® ,
please thoroughly read through this manual and follow all instructions!
Please make sure that nothing was damaged during the shipment of this item. In case
damage did occur during the shipment please go to Section 5 - Guarantee
1.1 Application of the Staufix®SWA
The KESSEL Staufix® SWA backwater valve
is designed to be installed in wastewater drainage pipes with or without raw sewage. The
backwater valve prevents wastewater from
backing up the drainage pipe during backwater / flooding. The SWA should be kept in good
operating condition and should be accessible
at all times. During normal conditions the backwater flap is in the vertical, free handing position. Wastewater draining out of the building
pushes the flap open and is allowed to flow
through the SWA and out of the building. The
SWA is equipped with a manual flap locking
valve which can be used to fully lock the flap
shut – allowing no wastewater in either direction to pass through the valve. In the case that
the drainage pipes connected to the Staufix®
SWA will not be used over extended periods of
time it is recommended that the flap is securely locked with the locking lever. Important is
that when the wastewater pipes return to service that the flap is unlocked. DIN EN 12056
and DIN EN 13564 should be followed which
regulated the drainage of building and use of
backwater valves.
1.2 Application Controfix®
The KESSEL Controfix® serves as the body
housing for all KESSEL Staufix® and Pumpfix
series backwater valves. The following installation instructions should be heeded. Since the
KESSEL Controfix® serves as a cleanout or
access to the drainage piping, the Controfix®
does not contain any backwater flaps and thus
does not offer any protection against backwater. Upgrade packages are available that can
be used to upgrade the Controfix® to any
KESSEL Staufix® or Pumpfix backwater valves.
1.3 Contents of Delivery
The Staufix® SWA delivery consists of a body
/ housing with cover including the emergency
closure lever (closure lever not included with a
Controfix® ), and installation and operating
manual (Article Number 010-841) and a seethru test funnel used for testing the valve after
installation (test funnel not included with a
Controfix® ).

2. Installation
General instructions for installation of backwater valves
According to DIN EN 12056 it is not allowed to connect all drainage fixtures from a building (including those located above the backwater level
– ground level) through a backwater valve. The reason being that when
the backwater flap is in the closed position due to backwater / flooding
no wastewater will be able to flow through the backwater valve meaning
that the building’s own wastewater will flood out of the lowest drainage
fixture connected (normally in the basement) to the backwater valve.
Incorrect installation of a backwater valve
Correct installation of a backwater valve
DIN EN 12056 specifically states that only drainage fixtures below the
backwater level may be connected to a backwater valve. All drainage
fixtures above the backwater level should be drained through a separate pipe directly into the sewer (not through the backwater valve). This
means that the home / building must be equipped with separate drai-
nage pipes. A building’s wastewater from above the backwater level
(above ground level) can drain freely into the sewer at all times. During backwater the higher head / pressure of wastewater above the
backwater level will force its way into the surcharged sewer and will not
flood the basement / lower levels. Rainwater drainage pipes must not

be connected to a backwater valve.
Please note:
DIN EN 12056 requirements should be closely followed during the planning and installing of drainage pipes! Vertical drainage pipes connected to a backwater valve
should not be connect directly in front of
the backwater valve but should be connected at least 1 meter before the backwater
valve – this is the so called ‘wastewater calming’ area. A backwater valves should also
be installed so that access to the valve for
service, maintenance or repair is possible.
CAUTION: Make sure that the backwater valve is installed in the proper direction and is not installed backwards.
KESSEL backwater valves are equipped
with flow direction arrows to make sure
that the valve is installed in the proper
direction.
2.1 Concrete slab installation of a KESSEL-
Staufix®SWA (Nr. 73100.10 S/X, 73125.10
S/X, 73150.10 S/X, 73200.10 S/X). This information is also valid for the installation of the Con-
trolfix® . The Staufix® SWA body should be installed perfectly horizontal (please see illustration 1). The included gasket should be placed into
the recessed area of the housing (as shown in
illustration 2) and then the upper portion of this
gasket should be lubricated. The included upper
section can then be inserted into the housing as
seen in illustration 3. After installation inspect the
gasket to make sure it has been installed properly.
CAUTION:
In the case that a shallow installation is
required in a concrete floor slab it may
be necessary to shorten the upper section which can be done by sawing off
the required lower portion of the upper
section. The maximum depth of groundwater the concrete slab Staufix®
should be installed in is 2 meters.
It is recommended that a conduit pipe
is laid and connected to the Staufix®
SWA body in the case that the system is
upgraded at a later date which would
require that a power cable is connected
to this system.

2. Installation
The second gasket must be inserted in the
cover. Important is that the sealing lip and
centering tip are pointing up. The centering
tip is to be inserted in the appropriate recessed area as seen in illustration 5. During installation the valve should remain clean and
it should be assured that no foreign objects
such as trash or debris are in the valve.
Recessed cover for on-site tiling (maximum
tile height including tile adhesive – 15mm)
The recessed cover (series X) allows the flooring material (tile for example) to also be installed in the recessed cover so that the finished cover matches the flooring surface. If
tiles will be placed into the recessed cover it
is important that the proper adhesive material is used and the following instructions are
followed:
Tiles
a) The inner surface of the recessed cover
should be coated with a bonding material
which sticks to ABS (such as PCI base
coat 303). After this surface coat has properly dried the tile surface can now be laid
into the recessed upper section by using
a silicon adhesive. This method is ideal for
thinner tiles since the remaining height
can be built up with the tile mortar.
b) Installing tiles with PCI-Silcoferm S (self
adhering silicone). This method is ideal
for thicker tiles since a thinner adhesive
surface is used.
Tiling with natural stone such as granite,
marble or agglomarmor
a) The inner surface of the recessed cover
should be coated with a boding material
which sticks to ABS (such as PCI base
coat 303). The natural stone surface can
then be laid into the covers using an appropriate adhesive (for example PCI-Carralit)
b) Installing a natural stone surface a with a
special silicon such as PCI-Carraferm.
Follow the same instructions as in the
‘Tiles’ section above.
2.2 Extended Depth Installation (Nr. 83071)
If the Staufix® SWA is to be installed in an
high groundwater or high earth moisture area
then the instructions in Section 2.4 must be
followed. Depending on the required depth
of installation, either one or two of the KESSEL extension sections can be used.
Connection gaskets are supplied with the
83071 and should be properly lubricated as
stated previously. In order to reach the properly installation height when using extension section(s) it may be required to shorted
the top upper section.
Caution! Using 3 or more extension sections
does not allow proper access to the valve for
service or repair and is not recommended.
2.3 Installation in Exposed Pipes (Nr.
73100.10, 73125.10, 73150.10, 73200.10)
The Staufix® for exposed pipe installation
is supplied with a protective cover to prevent
dust and debris of entering the system and
to also help prevent any type of damage to
the system. This protected cover is not
water tight. To remove the protective cover
simple lift both clips on one side of the cover
Before the black lower part of the protective
hood is dismantled, the feed and drain covers must be removed.
2.4 Installation in high groundwater /
earth moisture areas
In the case that the Staufix® SWA for concrete slab installation is to be installed in a
floor slab which will be protected against
Page 7
groundwater or earth moisture – sealing
gasket set 83023 must be used (accessory). If the concrete slab will be equipped
with a membrane or sheet – this sheet is to
be connected to the Staufix® SWA body
with the counter flange supplied with the
83023. In the case that a water proof concrete is being used then the heavy duty
Kautschuk seal (included with the 83023) is
inserted and then fixed tight with the counter flange. Please install the Kautschuk flange properly so that the pre-drillled holes in

3. Commissioning
Function / Sealing test according to DIN EN 13564
Manually lock the outlet side backwater flap with the manual closure lever (number 3 on illustration). Unscrew the
red ½ inch test plug (1) on the cover and connect the supplied see-thru test funnel (2). Add clear water into the funnel until the water level inside the funnel reached the 10cm
mark (this may require significant filling of water since the
Staufix® SWA body must first be completely filled with
water before the filter level is reached). Over a 10 minute
period, observe the water level inside the see-thru funnel.
If the water level decreases, refill to the 10cm mark and record how much water is required to keep the water level
at 10cm. If no more than 500ml of water was required to
keep the water level at the 10cm mark during the 10 minute test then the valve is considered tight.
