If the tap sometimes continues to drip after being turned off, this may be normal depending on the system, or it may be a sign of a malfunction. It is important to distinguish between high-pressure and low-pressure fittings.
Reasons why the faucet drips
Depending on whether you have a high- or low-pressure fitting, the dripping faucet is not necessarily a problem.
- With low-pressure fittings, it is more common for the tap to continue running for a short time after being turned off due to the way they work.
- However, if the water continues to run for a longer period of time, you should investigate the cause more closely.
- It is possible that the water pressure in the system is too high.
- In addition, the hoses in the system may have been installed incorrectly or may contain air.
- With a high-pressure faucet, dripping is usually an indication of a problem that can be traced back to limescale. In most cases, various components such as the valves, the valve seat, the cartridge in the single-lever mixer, or the aerator are calcified.
What you can do to stop dripping
Once you have identified the cause of the dripping tap, you can usually fix the problem quickly.
- If the dripping is caused by excessive water pressure, you should check the flow restrictor. This is located between the flexible hose and the angle valve. If it is damaged, you should replace it.
- If there is air in the device, you will hear a throbbing or knocking sound when you turn on the faucet. In this case, you will need to vent the entire system.
- Sometimes the problem is caused by incorrect installation of the hoses.
- For a low-pressure fitting, you must attach the air-permeable flexible hose to the boiler outlet with the red arrow pointing upwards. The hose with the blue arrow pointing upwards is connected to the angle valve and the hose with the blue arrow pointing downwards is connected to the boiler inlet.
- For high-pressure fittings, you should simply descale the relevant part of the system.
