What is a sanitary blockage and how do you notice it?
Plumbing includes everything in a home or business that supplies or drains water, such as toilets, showers, washbasins, sinks, bathtubs, and washing machine connections. A plumbing blockage occurs when waste, soap, hair, grease, or other residue accumulates in pipes. This can manifest as:
- Slowly draining water: Water remains in your sink, shower or washbasin for a long time and hardly drains away.
- Bubbling sounds: You hear bubbling from the drain, toilet or shower drain, caused by air that cannot escape normally.
- Unpleasant odor: Clogs often cause a pungent sewer smell because waste products are not sufficiently flushed away.
- Water coming back: Serious problems if water backs up from the toilet or floods when flushing.

If you recognise any of these signs, it is necessary to take immediate action to minimise damage and inconvenience.
How does plumbing unclogging work and what techniques do we use?
We from Ontstoppen.nl We use professional and safe techniques to quickly address any blockage. Our sewer specialists first analyze the cause of the blockage with a camera inspection. This allows us to pinpoint the exact location and cause of the blockage. We then select the appropriate unblocking method, without damaging pipes or plumbing fixtures.
- Mechanical spring machines: Rotating springs literally loosen and remove dirt and blockages from the pipe, ideal for stubborn plugs.
- High pressure cleaningA powerful jet of water completely loosens and removes grease, limescale, hair, and other residue from the drain. This technique works perfectly for long pipes or incipient sewer problems.
- Chemical-free unblockingWe avoid harmful drain cleaners, protecting you and the environment. With innovative methods like vacuuming or manual cleaning, waste can be removed safely.
- Replacement in case of serious damageIn rare cases involving heavy limestone or tree roots, we can replace or repair the material in consultation. We always make clear agreements beforehand.
Thanks to our advanced sewer rat cameras, powerful high-pressure pumps, and flexible tools, we can tackle any drainage problem thoroughly. This way, you'll quickly have running water and clean pipes again.

Frequently asked questions
How do I quickly and effectively resolve a sanitary blockage?

What are the most common causes of a plumbing blockage?
Plumbing blockages are usually caused by a buildup of grease, hair, soap scum, and toiletries residue that accumulates inside the drain pipes. In toilets, wet wipes, excess toilet paper, or insoluble materials are common culprits, while in showers or sinks, hair, toothpaste, or shampoo clump together, forming a tough clog. Lack of maintenance or improper plumbing installation can also cause blockages.
In addition to the causes mentioned above, an older plumbing system is susceptible to limescale or rust deposits, which narrow the pipe's diameter over time. Preventative cleaning, not flushing grease down the sink, and regularly cleaning grates will help prevent blockages.
