Hansgrohe Focus Low pressure sink mixer with (system-related?) Dripping problem ...

The supply of single-lever mixer was carried out as always with Amazon very quickly and at a reasonable price.
We are very pleased with the appearance and the processing. The fitting is facilitated continuous and adjustable swivel range. The working height is ideal for us.
The mixer has a height of about 33.5 cm and a spout height of about 27 cm above the pool or the worktop. From mid-riser by mid outlet is about 20.5 cm.
We had in our kitchen for many years a brand faucet with pull-out spray. This was also very high quality and never made trouble.
The big downside to our stainless steel basin was the low height of the short, slanting fitting. If you wanted to fill the tank of a water filter high things like, had to pull out the shower. Otherwise it was actually used very rarely for rinsing. Advantage was with the mixer, which is run after virtually nothing after turning off the water. During heating of the older low-pressure accumulator dripped course easily because the device does not stop dripping.

In the Focus mixer with the much higher spout and shower without the water now, which is located after turning even in the outlet pipe runs after. During heating of the undercounter unit it drips course easily.

I have the outlet pipe removed from the mixer to see why the water running after. In addition I have opened the mixing lever gently and closed (please do not try this, it could inject ...). The valve closes immediately to 100%. So it may be the hunting of water only the final balance of the high spout.
I would compare this situation with the aspiration of fluids by tube from a container. As the liquid passes, too long out of the tube until the tank is empty, or is withdrawn from the liquid ...

To mount another note, the flexible connection hoses are each about 75 cm long (roughly measured it). It is provided for the water connection, a flow limiter (no primitive plastic tubes!). For the ports on the storage two compression connections for the 8 mm tubes of the two connecting hoses from the mixer are required. These are not included because they would otherwise belong to storage?!?
I'd focus sink mixer, even if he runs after something definitely buy again and give here my purely personal experience / opinion again!
