We got a new dryer, which provides the ability to derive the condensed water directly.
since no sink .. is nearby, but right next to it is the washing machine, led the way for Baumnarkt.
The "Eckablaufanschlußteil" thus took on the drain hose to the washing machine and the dryer (9mm).
When Problelauf promptly pumped the washer the effluent into the dryer (to an internal check valve has been saved).
Wanted Found - 3 days Shipment - built-in - everything is good.
Prevents the return, but is also light enough to set the condensate from the dryer "released" to.
So not only recommended - but duty
