A kitchen sink can appear to improve after a temporary clearing and then become slow again. Prevention and diagnosis are different tasks: changing what goes down the sink is useful, but it does not identify or remove an existing obstruction. Describe whether the sink bowl holds standing water, whether the second bowl backs up and whether a garbage disposal is connected. A P-trap is the curved pipe beneath many sinks; tell the provider about known leaks or earlier trap work without taking it apart.
Fats, oil and grease in a blocked kitchen drain
Allow cooking fats to cool, collect them in a suitable container and put them in the appropriate waste stream. Scrape food from cookware before washing. Hot water is not a reason to dispose of grease through a drain. Portland’s Environmental Services guidance advises keeping fats, oils and grease out of drains and disposing of them appropriately.
A clogged double sink: one bowl or both?
Tell the provider whether one or both bowls retain water and whether the problem appears when the dishwasher drains. Mention a garbage disposal if present, but do not assume the disposal is the cause. These details help explain what needs to be assessed.
Grease buildup and other possible drain obstructions
Grease is one possible contributor, not a diagnosis that can be made from slow water alone. The request should describe what happens and how long it has happened. Keep records of earlier clearing work, especially when the improvement lasted only a short time.
Prepare access for kitchen sink unclogging
Clear stored items around the sink cabinet if safe and ask what access the provider needs. Keep chemical product packaging available if anything was poured into the drain. Confirm the visit fee and proposed clearing scope before work begins.
