Includes 1 1/4 inch (diameter approx. 4 cm) rod eccentric fitting (drain fitting) 3 flexible connection hoses 35 cm mounting kit surface: chrome low pressure fitting: the inlet to the low-pressure fitting (three connection hoses) is always open, so no pressure can build up in the memory.

This process is normal and cannot be prevented - no reason for complaint.
