The cabinet view and the drainage pattern work together
A photo beneath the sink helps show the waste arrangement, while the pattern of rising water helps identify what may be connected. Mention whether both bowls drain slowly, whether the appliance discharge causes backup and whether the problem developed gradually.
Grease and food residue are possible causes, but an object or unsuitable connection can also be involved. Do not assume that replacing the trap resolves every restriction. Ask the provider which part of the line was assessed and whether the observed result supports further investigation.
