When this kitchen drain problem occurs
Investigate restrictions beyond the immediate sink trap in a kitchen branch drain. The cause can depend on where the restriction sits, the type of sink and disposal setup, and whether other fixtures are affected.
Details that can help
- Whether the sink drains slowly or does not drain at all.
- Whether one basin or both basins are affected.
- Whether the disposal makes unusual sounds or stops working.
- Whether the clog returns after a temporary clearing.
What to do next
Stop using the sink if water is rising or backing up. Avoid mixing drain-cleaning products. Explain what you observe and any steps already attempted when contacting a service provider.
