too insensitive and too quiet, only eigeschränkt available, failure to mention Eischränkungen

After flooding / flooding in the basement (where the water eventually hinläuft) I have 2 different detectors Ordered to test only times which work well to then equip all my basement with detectors. If clean tap water bad already in rainwater or not working at the mumbi but and is in contrast to the also ordered ABUS water detectors HSWM10000 much quieter. The Abus reacts immediately with all types of water, whether in the garden pond, even at highly contaminated waste water and is much louder than the mumbi. I no longer hear well through the basement ceiling to the top, the mumbi. Good at ABUS I like the alternative the sensor on the cable to pull out and possibly separately to install it from the detector. Will the cable extend to a detector and so install the sensor in the basement and the actual detector on the ground floor. Then I hear definitely also at night in his sleep a signal from the basement. The Mubi you can only next / under a dishwasher or use so and he is too quiet. This restriction only 2 stars from me. The ABUS also purchased I will assess separately.
