Add a sewer scope before buying this 210 m² Seoul flat?

[long_door]

I have the general inspection booked for a 210 m² new-build flat in Seoul, but the inspector excludes the private sewer line. The description is slightly confusing: the flat is new-build, while I’ve been told the home or drainage connection is older, and there are mature trees near the street.

A separate scope costs far less than the ₩28,980,000 estimate I received for a full replacement. Is it sensible to add one without obvious warning signs, or am I investigating something that may not even be my responsibility?

Before deciding, establish what “private sewer line” means for this particular flat. Does it serve only your unit, the whole building, or part of the development? A scope could be worthwhile given the replacement estimate, but only if it examines a section you might actually have to repair.

I’d add it if access is straightforward and the cost is modest relative to ₩28,980,000. Mature trees and an older connection are enough uncertainty for me; warning signs often appear after the convenient inspection window. Still, ask what portion can actually be viewed and whether you receive clear findings rather than just a pass/fail answer.

I’m less convinced until the new-build/older-home contradiction is cleared up. If the drainage was installed with the new flat, the age argument changes. If a new unit was connected to older shared infrastructure, it changes again. Ask the seller, inspector and building management the same question separately: which pipe is old, where does it run, and who pays if it fails?

Also compare the scope cost with what remains after moving costs, the first mortgage payment and any immediate repairs from the main inspection. Spending a little to investigate a potentially huge problem can be rational, but not if it empties the emergency fund before you know whether the pipe belongs to the flat.

One more thought: don’t let the furniture budget make this decision. Furniture can be delayed; drainage trouble cannot. I would wait for the general inspection findings, confirm responsibility for the line, then book the scope promptly if either point remains concerning.

There’s a middle position here. Ask whether building service charges cover shared drainage and what insurance, if any, would leave you paying an excess or excluded repair costs. Those answers may reduce the ₩28,980,000 exposure substantially—or show that the estimate really does matter to your purchase decision. Seoul-specific responsibility can depend on the building arrangements, so assumptions are risky.

My practical sequence would be: resolve why a new-build flat has an older stated connection, identify the exact section included in the replacement estimate, confirm who maintains that section, and ask the scope provider what access and reporting are included. If it is your liability and most of the line can be inspected, the price difference makes the scope an easy choice. If it is shared or inaccessible, spend the money only after clarifying what useful information the scope can deliver.
