A qualified person can disassemble and inspect the valve by
opening the four Allen screws without voiding the warranty.
(Note the position of the pressure spring and the two O-
rings when opening)!
To better detect possible foreign bodies when opening the
valve, it is best to drain the residual water through a white
cloth into a bucket.

The video is in English, but shows very well the individual
steps even without language skills, please note: Do not
execute point 1., because the FlowTimer+ electronics can
not be separated from the coil!
If leakage is still not indicated according to chapter 8.3
"Verifying the tightness", please contact our customer
service at info@use-tech.de .
Pictures of the installation location of FlowTimer+ as well as
the respective peripherals (softening, pressure boosting,
pump station, osmosis etc. ) are also helpful.
