Please see below video on how to unclog the kitchen drain and shower drain.
Removing a blockage in the drain is the tenant's own expense and responsibility. Most blockages are located shallowly in the drain: in the drain, the swan neck or drain pipe towards the sewer.
Do you live in an apartment complex? Then it is possible that the blockage is in the shared standpipe. If you have tried to remove the blockage yourself and this did not help, you can submit a repair request via the LIV app. Please note: if the blockage is in the drain within your home, it is possible that the costs to remove it will be charged to you.
