If your sink keeps backing up in Calpe, you need an experienced plumber who can work out whether the problem is a local blockage, a partially blocked trap, or a fault further along the waste pipe.
100% Plumbing is based in Calpe and deals with recurring blockages, slow drains and wider drainage problems for homes and businesses across the Marina Alta.
If a sink drains normally for a while and then backs up again, the obstruction was probably never fully removed. A blockage that keeps returning is a different problem from one that happens once.

Why does my sink keep backing up?
A sink that keeps backing up is usually a drainage restriction rather than a one-off blockage. The most common causes are:
- grease and food waste building up in kitchen pipework;
- soap residue, hair or debris in bathroom drains;
- a partially blocked trap;
- a blockage further along the waste pipe;
- poor drainage flow;
- a wider drain problem affecting several fixtures.
The position of the blockage matters more than the symptom. A trap can be cleared in minutes; a fault further down the waste pipe cannot.
What are the signs of a deeper drain problem?
Sometimes the sink is only where the problem shows. These signs point to something beyond that one fixture:
- more than one sink draining slowly;
- water backing up into another fixture;
- gurgling from nearby drains;
- persistent bad smells;
- repeated blockages after basic cleaning;
- water rising in the sink when another fixture is used.
When several fixtures are affected at once, clearing the sink on its own will not hold. The drain itself needs attention.
Can I fix a backing-up sink myself?
Sometimes, partly. It depends on where the blockage sits and whether you can reach it safely.
Worth trying yourself
- removing visible debris from the plughole;
- cleaning the trap, if it is accessible and you can do it safely.
Rarely solves it
- strong chemical drain cleaners;
- repeating the same temporary fix each time it returns.
Chemicals and repeated quick fixes are unlikely to resolve a deeper problem, and they can make the later repair more complicated. A professional diagnosis establishes whether the fault is in the trap, the waste pipe, or further along the system.
When does a backing-up sink become urgent?
An occasional backup is not usually an emergency. It becomes one when the sink cannot be used, water overflows, or several drains are affected at the same time.
Treat as urgent
- dirty water backing up into the sink;
- a kitchen used for food preparation is affected;
- overflow onto floors or into cabinets;
- strong, persistent smells;
- a rental, restaurant or business is affected;
- toilets, showers or other drains starting to back up.
Book a normal appointment
- the sink drains, just slowly;
- the problem comes and goes;
- only one fixture is affected;
- there is no overflow and no smell.
If water is actively overflowing or there is a risk of damage to the property, that is a case for emergency plumbing services.
Why recurring sink blockages should not be ignored
A blockage that keeps coming back is telling you the underlying cause is still there. Drainage improving for a few days does not mean the pipe is clear: grease, debris or scale can remain in place and build up again from the same point.
Left untreated, drainage can stop altogether, or waste water can start backing up into other parts of the property. Dealing with the cause early is what prevents that.

Why local plumbing help in Calpe and the Marina Alta matters
A blocked sink is disruptive anywhere, but the properties here make it worse. Apartments, villas, holiday rentals, restaurants, bars and commercial premises all share the same issue: the problem reaches someone else fast.
Guests and tenants notice within hours. In a restaurant or a bar, a kitchen sink that will not drain stops the service. A local plumber can get there and establish whether the fault is isolated to that sink or part of a wider drainage problem.
