The 7 Most Common Plumbing Issues in Belgium (and How to Prevent Them)

Belgian households often face recurring plumbing issues due to hard water, cold winters, and older infrastructures. Here’s a detailed look at the most common plumbing problems – and how to avoid expensive repairs.

1. Clogged Drains

Hair, grease, soap scum, and food waste are the most common culprits, especially in bathroom and kitchen sinks.
✅ Prevention: Use drain strainers, avoid pouring grease down the sink, and clean out traps monthly with a natural mix of baking soda and vinegar.

2. Leaky Faucets

A constant drip wastes water and money over time.
✅ Prevention: Replace washers or cartridges early. If dripping continues, it may be time to replace the tap or call in a plumber.

3. Running Toilets

Often unnoticed, a leaking cistern can waste over 100 litres per day.
✅ Prevention: Listen for running water after flushing. If it doesn’t stop, have the internal mechanism checked or replaced.

4. Low Water Pressure

Frequently due to lime-scale buildup in pipes or faucet aerators.
✅ Prevention: Install a water softener system in hard water areas like Liège. Clean showerheads and faucet filters regularly.

5. Frozen Pipes in Winter

When pipes freeze, they can burst and flood your home.
✅ Prevention: Insulate any exposed pipes, especially in basements, attics, and outside walls. Let taps drip slightly during freezing nights.

6. Bad Smells from Drains

Foul odors can come from a blocked or unventilated pipe system.
✅ Prevention: Clean traps and drains monthly. A mixture of hot water and vinegar helps eliminate bacteria and buildup.

7. Boiler Breakdowns

Very common during the winter months when demand peaks.
✅ Prevention: Schedule your mandatory annual maintenance. A certified heating plumber will catch issues early and keep your system efficient.
