Avlopp Stockholm: Typical Problems and How to Avoid Them

To live in such a lovely, historic city as Stockholm is to have its advantages—but with plumbing, the city's history and environment bring some special considerations. You may live in a quaint apartment in Södermalm, a villa in Bromma, or be the landlord of an apartment building in Vasastan, but issues with Klopp (drain and sewer) are not unusual.

In this blog post, we'll explore avlopp Stockholm’s most common drainage issues, the reasons behind them, and—most importantly—how to prevent costly and unpleasant surprises in your home or building.

Understanding Avlopp in Stockholm

In Sweden, "Avlopp" refers to wastewater and drainage systems, including:

• Kitchen and bathroom drains

• Sewer pipes

• Stormwater drains

• Stack pipes (stammar)

• Floor drains and outdoor gullies

Stockholm's infrastructure is a combination of old and new. Many inner-city apartments retain decades-old plumbing systems, while newer apartments are constructed to current standards. However, whether new or old, all drainage systems require periodic maintenance and attention to operate flawlessly.

1. Clogged Drains

Why does it happen?

The most prevalent problem in Stockholm is clogging—particularly in bathrooms and kitchens. Grease, hair, soap scum, and food particles settle over time, limiting water flow.

Older pipes are more susceptible, especially those made from cast iron or narrow copper pipes common in historic Stockholm properties.

How to prevent it:

• Never pour grease down the drain. Use a container and dispose of it in the trash.

• Use strainers in sinks and showers to catch debris.

• Schedule professional drain flushing (spooning) once a year, especially if you live in an older home.

2. Bad Odors from Drains

What causes it?

Organic buildup clogged dry traps, or drainage system ventilation problems tend to produce foul odours. In structures with older or less maintained pipes, sewer gases may leak back inside.

How to prevent it:

• Drains in infrequently used areas (such as laundry rooms or basements) should have water run through them occasionally to fill up the traps.

• Drains can be cleaned using baking soda and vinegar every month.

• If odours remain, a professional drain inspection with a spell (flushing truck) might be necessary to find the source.

3. Slow Draining Water

What is the cause?

Slow draining indicates a partial clog or sediment and soap buildup on the pipe walls. It can also be caused by tree roots penetrating the sewer line—a widespread issue in Stockholm's green neighbourhoods.

How to prevent it:

• Flush your main drains professionally with stamspolning (main line flushing) every few years.

• Install root barriers close to underground pipes in gardens or courtyards.

• Fix any drainage problem early—slow drainage is the first warning sign of a complete clog.

4. Flooding or Water Backups

What causes it?

Backups can happen when intense rain exceeds storm drains or when pipes clog. Clogged main lines and floor drains in Stockholm's older buildings can cause sewage to go back into lower floors or basements.

How to prevent it:

• Remove gravel, leaves, and dirt from outside drains.

• Install backflow preventers to keep sewage out of your house.

• Have an Avlopp expert periodically check your property, especially before the rainy autumn months.

5. Leaking or Cracked Pipes

What causes it?

Extreme cold in winter can cause pipes to swell and crack, especially in areas without heat. Movement in the ground and corrosion also cause pipe damage in older homes.

How to prevent it:

• Insulate pipes in crawl spaces, attics, and basements.

• Get a camera inspection (rörinspektion) if you see signs of pipe damage.

• If repairing, substitute worn metal or ceramic pipe with new, durable material.

6. Grease and Sludge in Sewer Lines

Why is this?

Grease and sludge can get into restaurants, cafes, or home sewer lines that process food and cook regularly—leading to clogs and stinky odours. Stockholm's cooler weather causes fat to become solid quickly in pipes.

How to prevent it:

• Install a grease trap if you're a food-service establishment.

• Do not dispose of oil or fatty food scraps in the sink.

• Have a subtle (vacuum truck) used to clean sludge and grease from drains as part of routine maintenance.
