Drain unblocking services in Calpe
Blocked drains can happen in homes, villas, rental properties, restaurants, shops and commercial premises. In Calpe and nearby Costa Blanca areas, common causes include grease, soap residue, hair, food waste, scale, older pipework, poor drainage flow, outdoor debris and repeated build-up inside the pipes.
A blocked drain may start as a slow sink or shower, but it can become more serious if wastewater begins to back up or if several drains are affected at the same time.
You may need professional drain unblocking if you notice:
- Water draining slowly from sinks, showers or baths.
- A toilet that will not flush properly.
- Gurgling sounds from drains or plugholes.
- Bad smells from sinks, showers or outdoor drains.
- Wastewater backing up into the property.
- Several drains blocked at the same time.
- Repeated blockages after temporary fixes.
- Water pooling around outdoor drains, terraces or utility areas.
100% Plumbing provides general plumbing services for blocked drains, pipework problems, leaks, pressure issues and related plumbing repairs.
Why call a professional to unblock a drain?
A professional plumber can identify whether the blockage is local, such as a sink trap or shower drain, or whether it may be deeper in the drainage system. This is important because repeated blockages often indicate a larger issue that needs proper inspection.
Using harsh chemical cleaners or repeatedly forcing water through the drain can damage pipework, seals and surfaces. It can also make the repair more difficult if chemicals remain inside the pipe when the plumber arrives.
A professional drain unblocking service can help reduce the risk of:
- Wastewater backup
- Bad odours
- Pipe damage
- Recurring blockages
- Water damage
- Hygiene problems
- Disruption to rental guests, customers or family life
If the blocked drain is linked to a wider plumbing issue, 100% Plumbing can also advise on suitable repairs or maintenance.
When is a blocked drain an emergency?
A blocked drain should be treated as an emergency if wastewater is backing up, toilets cannot be used, water is overflowing, or strong sewage smells are spreading through the property. It is also urgent if the blockage affects a holiday rental, business, restaurant or occupied property where the bathroom or drainage system cannot be used safely.
Call 100% Plumbing urgently if:
- Wastewater is coming back through a sink, shower, toilet or floor drain.
- More than one drain is blocked.
- A toilet is overflowing.
- There is flooding inside the property.
- There are strong sewage smells.
- The blockage keeps returning.
- You cannot use essential bathroom or kitchen facilities.
