A dripping pipe outside is usually warning you about an internal water-level fault. Here is how to identify the likely source, what not to do and when to arrange a repair.
An overflow is designed to let excess water escape safely when a cistern, tank or appliance is overfilling. The important job is to identify what the pipe serves, rather than treating the outside pipe itself as the part that has failed.
A fill valve that does not shut off can let the cistern overfill and discharge.
A faulty ball valve in a storage cistern can keep allowing water into the tank.
A pipe linked to heating or hot water needs careful identification before any repair is suggested.
Do not block, cap or seal an overflow. It is there to provide a safe route for excess water. Avoid climbing ladders or trying to reach a high-level pipe. If dripping water is causing damage, place a suitable container beneath it only where practical and safe.
If the source is a toilet cistern, the underlying fault is often a fill valve that is no longer shutting off properly. A cold-water storage tank can have a similar issue with its ball valve. In both cases, the sensible repair is usually to correct the water-level control, not to alter the overflow pipe.
Where the source cannot be identified, several appliances could be involved, or the pipe appears connected to a boiler or unvented hot-water safety system, it should be assessed by the appropriate specialist before a repair is promised.
A dripping overflow is usually a symptom that something is allowing water to overfill. Common causes include a toilet fill valve not shutting off or a fault with a cold-water storage tank valve. The visible pipe is not normally the part that has failed.
No. Do not block, cap or seal an overflow pipe. It is there to provide a safe escape route for excess water, and blocking it can force water back into the property or cause another problem.
Yes. A toilet cistern fill valve that does not shut off can cause the cistern to overfill and discharge through an overflow. If you can identify the toilet as the source, a fill-valve repair is often the practical solution.
Arrange help promptly if the water is causing damage, the flow becomes heavy or continuous, or you think it may be a boiler or unvented hot-water safety discharge. Do not climb to reach a high pipe or interfere with a safety outlet.
