Kitchen Sink Slow but Not Clogged
A slow kitchen sink is often grease-related, but when the problem keeps returning or appears alongside other slow drains, the main line may deserve a closer look.
Common causes we see
- Grease buildup close to the sink or branch line
- Older drain piping with residue narrowing the line
- Main sewer line restriction if other fixtures are also affected
- Standing water in a sewer belly that slows system-wide drainage
These are exactly the kinds of issues a sewer camera inspection is designed to document before you pay for major work.
Why you should not ignore it
- Repeated temporary fixes can hide a bigger issue for too long
- If the sink backs up when other water is used, the issue may go beyond the kitchen drain
- Proper diagnosis can save money compared with repeated snaking without documentation
How GroundTruth helps
GroundTruth can help when the symptoms suggest the issue may extend beyond the sink itself. Sewer camera inspection gives you a clearer picture before you keep paying for short-term drain cleaning.
We are inspection-only. That means no repair sales pressure tied to the diagnosis. You get video + written documentation and can use the findings with the contractor of your choice.
Best next step
If this sounds like what you are seeing at your property, the smartest move is to document the line before the next rain event, laundry day, or backup makes the decision for you.
When hydro jetting becomes the better answer
Kitchen drain problems are often grease-related. When the line is structurally sound, hydro jetting can clear the buildup more thoroughly than a quick spot cleaning. A camera inspection helps confirm whether the issue is buildup, roots, or something else.
GroundTruth provides independent inspection-first documentation so you can decide whether monitoring, cleaning, or repair is the right next step.
