GROHE SenseCheck
YOUR GUIDE TO THE GROHE SENSE GUARD INSTALLATION
For safety advices, please see the product manual included in the packaging (sensecheck.grohe.com/manual)
The GROHE SenseCheck is designed to help installers and end users with the installation of the GROHE Sense Guard.
We recommend that the SenseCheck is done by an installer together with the inhabitant of the house/end user
where the Guard is being installed.
CAN THE GROHE SENSE GUARD BE INSTALLED AT THE LOCATION?
PLEASE NOTE THAT THE GROHE SENSE GUARD HAS BEEN DEVELOPED FOR THE FOLLOWING SITUATIONS:
single family houses
only one person is able to decide to shut off the water supply, without negative impact on other inhabitants
BE AWARE THAT THE GROHE SENSE GUARD CANNOT BE INSTALLED:
on hot water pipes
outside the house
in rooms with frost risk
when flow pressure is below 0.05 Mpa/0.5 bar/7 psi
when flow pressure is higher than 1 Mpa/10 bar/145 psi (can be solved by pressure reducer)
in high pressure gravity pumped water systems
General remark: The micro-leakage test is limited to the cold water pipe. Smaller leakages on the hot water pipe may not be
detected.

1. PLAN
1.1 Is there enough room?
(between water meter and where pipe splits to the heating system)
The GROHE Sense Guard needs to be installed between the water meter and the junction between hot and cold water.
GROHE Sense Guard needs to be installed as close to the water meter as possible for maximum water security.
Please consider the dimensions below and make sure that there is enough room to install the device downstream.
Please note that room for 2 stop valves (to be installed before and after the GROHE Sense Guard) is needed. We
recommend to install the GROHE Sense Guard with a wall mount set to ensure an easy and stable installation (product
# 22501000).
Material needed for installation:
□ Adapter for different pipe sizes
□ Other material: ___________________________________________________________________________.
GROHE Sense Guard dimensions:
GROHE Sense Guard Wall Mount Set dimensions:
1.2 Is there a power outlet available to power the GROHE Sense Guard, located above the water pipe?
The power plug needs to be installed above the level of the water pipe. The provided cable has a length of 70cm. If the
length is too short, please make sure to order the extension cable (product #22521LNO) or have an extra power plug
installed.
1.3 Is there a stable Wi-Fi signal at the potential location of the GROHE Sense Guard?
First, make sure that:
your smartphone is connected to the internet via Wi-Fi or mobile data.
your router doesn’t have any offline times or shifts to battery saving mode during night.
Please check the Wi-Fi connectivity at this location with your smartphone:
OPTION 1: Download a Wi-Fi analyzer app (e.g. Android: Wi-Fi analyzer, iOS: Wi-Fi SweetSpot) and check for
connectivity stability for 5 minutes on the app.
OPTION 2: Use a mobile phone’s connectivity indicator. Check for connectivity stability for a period of 5 minutes.

What to do if Wi-Fi connection is weak?
PROBLEM
TEST
SOLUTION
The distance from
the router is too long
Check the Wi-Fi
performance while walking
away from the router
To solve this issue, either a repeater or a new router
with a better performance can be installed
Obstacles such as
thick walls and
liquids weaken the
Wi-Fi signal
Test the Wi-Fi performance
on the one side of the wall
and compare it to the other
side
Use powerline adapters, which can carry the Wi-Fi
signal over the electric system of the house
Overlapping Wi-Fi
networks in one area
Routers use channels from
1 to 11. Wi-Fi analyzer apps
show how frequently the
channels are used.
Change the channel on the router manually to a
channel that is not overloaded. Please refer to the
manual of the router for changing the channel
Too many devices
use the same Wi-Fi
network
The app shows how fast the
Wi-Fi is
Install a router with a larger capacity or use meshed
Wi-Fi routers
1.4 Which of the following main heating devices for heating water is installed in the house?
Devices in the water system?
What to do?
□ Flow heater
Turn off the micro-leakage test later in the device settings of the GROHE
ONDUS app. With flow heater, the micro-leakage test that is done via
pressure measurement might not work properly.
□ Central heating
Only install GROHE Sense Guard on a cold water pipe.
With a central heating system, separate hot and cold water pipes enter the
apartment. GROHE Sense Guard cannot be installed on the hot water pipe.
Therefore, any leakage on the hot water pipe cannot be detected.
□ Hot water boiler
Hot water boiler with pressure compensation container:
No further changes needed.
Hot water boiler without pressure compensation container:
Turn off the micro-leakage test later in the device settings of the
GROHE ONDUS app. With a hot water boiler without a pressure
compensation container, the micro-leakage test that is done via
pressure measurement might not work properly.

1.5 Check if the flow pressure is between 0.05 and 1 MPa (0.5 and 10 bar/7 and 145 psi).
GROHE Sense Guard operates ideally with an incoming flow pressure between 0.1 and 0.5 MPa (1 and 5 bar/7 and 145
psi). If you are not sure about the water pressure in the house, please contact your water utility.
Flow pressure
What to do?
Pressure is between 0.05
and 1 MPa (0.5 and 10
bar/7 and 145 psi)
No further actions are needed or no limitations apply. But please note that GROHE
recommends a flow pressure between 0.1 and 0.5 MPa (1 and 5 bar/7 and 145 psi).
If pressure is higher than 0.5MPa (5 bar/72 psi) a pressure reducer is recommended.
Pressure is below 0.05 MPa
(0.5 bar/7 psi)
GROHE Sense Guard cannot be installed.
Pressure is higher than
1 MPa (10 bar/145 psi)
A pressure reducer has to be installed upstream the GROHE Sense Guard location.
1.6 Are any pressure-influencing devices installed downstream of the potential GROHE Sense Guard location?
The GROHE Sense Guard measures the downstream water pressure in the system. All pressure-influencing water
appliances need to be installed upstream of GROHE Sense Guard. In case these appliances cannot be installed
upstream of the GROHE Sense Guard, the Micro-Leakage detection might be influenced and therefore needs to be
turned off. Exception: Upstream the hot water system, backflow preventers / pressure compensation containers are
needed to ensure functionality of the GROHE Sense Guard.
Please check for any appliances downstream the potential location of the GROHE Sense Guard that might affect the
water pressure.
Devices in the water system?
What to do?
□ Pressure reducers
□ Water filters
□ Backflow preventers
□ Booster pumps
□ Water softeners
□ Others
OPTION 1: Branch off pressure affecting devices upstream of GROHE Sense
Guard
OPTION 2: No micro-leakage test possible, turn micro-leakage test off
OPTION 3: Install pressure-influencing devices upstream
1.7 Are any devices installed that have a cyclic or permanent flow of water?
(downstream of the potential location of the GROHE Sense Guard)
GROHE Sense Guard measures water flow to detect leakages. If appliances permanently or cyclically consume water
this functionality cannot work properly.
Devices in the water system?
What to do?
□ American fridges/permanent ice makers
□ Aquariums with permanent fresh water flow
□ Permanent garden drop sprinklers
□ Drinking water sprinklers
□ Descaling devices
□ Other devices that have a cyclic or permanent
flow of water
OPTION 1, for devices with cyclic water draw off:
Modify the GROHE Sense Guard settings,
see instructions below1.
OPTION 2, for devices with permanent water draw
off:
Branch off devices with permanent flow of
water upstream of the GROHE Sense Guard
or the GROHE Sense Guard cannot be used.
Please note that leakages in pipes that
bypass the GROHE Sense Guard cannot be
detected.
