Insufficient digital control switch at low pressure
In the low pressure range, the pump switches on and off constantly, and since it is not whisper-quiet, this is occasionally annoying. I used to have another model that didn't work audibly, even drop by drop, so I'm not entirely satisfied with this model. I use the pump to fill the flush tanks in the toilets with salt water, and the constant switching on and off bothers me, especially at night.
