If your toilet cistern is leaking in Calpe, you need an experienced plumber who can identify whether the problem is the inlet valve, the flush mechanism, a worn seal or the connection to the water supply.
100% Plumbing is based in Calpe and repairs faulty valves, seals, connections and running toilet problems across the Marina Alta.
Where the water appears tells you most of the story. Water running continuously into the bowl points to an internal valve or seal. Water on the floor or around the outside of the toilet points to a connection, a gasket or the cistern body itself.

What causes a toilet cistern to leak?
Most cistern leaks come down to a worn part rather than a failure of the toilet itself. The usual causes are:
- a faulty inlet or fill valve;
- a worn flush valve seal;
- damaged washers or internal seals;
- a loose water supply connection;
- corrosion or deterioration inside the cistern;
- incorrect water level settings;
- a damaged cistern-to-bowl seal;
- cracks in the cistern.
How do I know if my toilet cistern is leaking?
Cistern leaks are easy to miss, because many of them never put water on the floor. These are the signs worth checking:
- water running continuously into the bowl;
- the cistern refilling when nobody has flushed;
- water around the base or the rear of the toilet;
- dampness near the supply pipe;
- unusual hissing or filling sounds;
- a noticeable rise in water use.
A toilet that keeps refilling can waste a considerable amount of water over time, which is why an internal leak is still worth fixing even though nothing is visibly wrong.
Can a leaking toilet cistern be repaired?
Often, yes. Replacing a faulty valve, washer, seal or connection is usually enough to restore normal operation, and the whole toilet rarely needs replacing just because the cistern leaks.
Usually a repair
- a faulty inlet or fill valve;
- a worn flush valve seal;
- damaged washers or internal seals;
- a loose supply connection;
- an incorrect water level setting.
Replacement may be better
- the cistern is cracked;
- it is heavily worn;
- several internal parts are failing at once.
An inspection settles which applies. It is a short job and it avoids replacing a toilet that only needed a new valve.
When is a leaking cistern urgent?
A cistern that runs quietly into the bowl wastes water but is not an emergency. It becomes one when water escapes outside the toilet, cannot be isolated, or starts to damage the property.
Treat as urgent
- continuous leaking outside the toilet;
- the cistern is overflowing;
- the toilet is unusable;
- the leak is reaching another room or property;
- it is a rental, holiday home or business;
- water is near electrical fittings;
- walls, flooring or furniture are getting wet.
Book a normal appointment
- water only runs into the bowl;
- the cistern refills occasionally;
- nothing is wet outside the toilet;
- the supply can still be isolated.
For a severe leak or active damage to the property, that is a case for emergency plumbing services.

Why local toilet repair in Calpe and the Marina Alta matters
A leaking toilet is awkward in a home and worse in an apartment, a holiday rental, a restaurant or a business, where it affects someone else straight away.
In holiday and rental properties there is a second problem: a small internal leak can run for weeks with nobody there to hear it, and the first sign is the water bill. A local plumber can check the toilet, the supply connection and the pipework around it, so the repair deals with the cause rather than the part that happened to be wet.
