Thank you @Newboy!
I'll try to fix the dishwasher waste as you suggested to prevent potential d/w filling with waste water.
What should I do about the d/w connection above the trap? Should it be below the trap? Can that have some disadvantages?
Hi all!
Could someone please help me understand what went wrong so that my sink has become unbearably noisy during dishwasher pumps water out. The water is going down pipes and makes a loud noise.
I have replaced an old dishwasher with the new one some time ago. I don't know if it is...
