Is your shower dripping? The cause is usually a worn-out seal or faucet cartridge. However, the fault isn't always in the faucet; it can be found in an unexpected place – and the repair can be done without a plumber or expensive spare parts.
Before you pick up the phone or head to the hardware store, check these three common causes. You'll easily save both time and money.
1. The culprit is the showerhead, not the faucet
When you turn off the shower, the showerhead and hose remain full of water. It is normal for this water to drain out by gravity over the next minute. This is not a leak.
The problem only exists if the dripping continues for a long time or starts again on its own. An old or poorly designed showerhead may collect water behind an airlock, from which it is slowly released one drop at a time. Limescale buildup exacerbates the situation as it blocks the natural drainage path of the water.
How to fix it:
-
Clean the showerhead: Remove the showerhead and submerge it in a vinegar solution (e.g., half vinegar, half water) for a couple of hours. Brush the nozzles clean with an old toothbrush and rinse thoroughly. This will remove limescale and ensure the head drains properly.
-
Consider a new showerhead: If the showerhead is old and worn, its internal channels may no longer drain effectively. Modern showerheads are designed to minimize post-drip.
2. Limescale and sediment – the invisible enemy inside the faucet
Water in Finland can be hard in some areas, meaning it contains plenty of limescale and other minerals. Over time, these minerals crystallize in the piping and faucet components. Even if you don't see limescale on the surface of the faucet, it can be lurking hidden inside.
The heart of the faucet is the ceramic cartridge that controls water flow and temperature. If even one small particle of limescale or rust gets between the ceramic plates of the cartridge, the faucet will no longer close tightly. The result is a continuous, slow leak directly from the spout or shower.
The leak is almost imperceptible at first, but it worsens over time as the water carves an increasingly larger groove around the particle.
How to fix and prevent it:
-
Cartridge replacement: A damaged cartridge must be replaced with a new one. This procedure can usually be done at home, provided you get the correct spare part.
-
Preventative measures: The best way to protect the faucet and the entire shower is to install an efficient sediment filter between the faucet and the shower hose. It filters out all particles larger than 5 microns from the water, such as limescale flakes, rust, and metal. The filter significantly extends the life of the faucet cartridge and keeps the showerhead nozzles clear.
3. Too high or fluctuating water pressure
A rarer but serious cause is excessively high water pressure. Every water system is designed to operate within a specific pressure range. If the property's pressure regulator is faulty or incorrectly adjusted, continuous overpressure strains all water fixtures.
High pressure forcefully wears down the faucet's seals and cartridge with a force they cannot withstand. This causes premature wear of parts and leads to leaks. A clear symptom is a sharp bang or rumble in the pipes when you quickly turn off the faucet.
How to identify and act:
-
Listen to the pipes: If closing faucets causes thumping sounds inside the walls, the pressure is likely too high.
-
Call a professional: Measuring and adjusting water pressure is the responsibility of the housing association or an HVAC installer. If you suspect a pressure problem, contact the property manager or a plumbing company. Fixing the fault protects all household water fixtures from expensive damage.
The next time you notice your shower dripping, don't immediately assume the worst. Go through these three points – the problem might be surprisingly easy to solve.
Frequently asked questions
Is it normal for a shower to drip for a moment after use?
Yes. It is normal for the showerhead and hose to drain water for about a minute after use. If the dripping continues for longer or starts again after a short while, the fault is likely in the faucet.
Can a dripping shower significantly increase the water bill?
Yes. Even a seemingly slow leak can waste hundreds, even thousands of liters of water per year. Constantly dripping hot water is particularly expensive, as it consumes not only water but also heating energy.
How do I best clean limescale from a showerhead?
Remove the showerhead and submerge it in a mixture of vinegar and water (1:1 ratio) for a few hours. Then, brush the nozzles open with a soft brush and rinse thoroughly. Avoid strong chemicals, as they can damage the showerhead's coating.
