Kitchen Sink Backed Up? There's a Reason It Happened Here

Korean kitchens have no garbage disposals — every drop of oil and every grain of rice goes through the pipe as-is. Add a winter cold snap that sets the fat, and a line that drained fine for months stops in one evening. We deal with this every single week.

Symptoms we hear from expat kitchens

Water sits in the basin for minutes after doing dishes, then glugs down all at once
Both bowls of a double sink fill together — the blockage is past the shared trap
A sour, oily smell drifts up even when the sink is empty
Your officetel kitchenette drains fine until laundry runs, then backs up — long thin lines to the riser are common in these buildings
Drain cleaner from the mart helped for two days, then everything stopped again
You just moved in and the sink was already slow on day one — that clog belongs to the pipe's history, not to you

Running a restaurant or cafe? Restaurant kitchens and floor trench drains are quoted by scale. Text us photos of the trench drain or grease trap and the kitchen layout — we quote commercial jobs the same way: a number you approve before anything starts. The full commercial version — trench drains, the grease-interceptor boundary and scheduled intervals — is on restaurant & cafe drain jetting.

How we clear it

1 · Photo of the sink and cabinet

One shot of the basin, one of the pipes under the sink. That tells us the trap type and what machine to bring, and you get a range by text.

2 · Trap first, then the line

Plenty of kitchen clogs live in the trap and fittings right under the sink. We check there before running a machine deeper — no point charging you for distance the clog never reached.

3 · Quote before the machine spins

Once we know where the blockage sits, you get one fixed figure with the VAT-included total. Approve it, and only then does the work start.

4 · Hot-water flow test

After clearing, we run hot water at full flow for several minutes to confirm the line carries it, reassemble everything dry, and hand you the receipt.
