Bosch - Buderus Combi Boiler Water Filling Tap Valve

Purpose of Use

When the combi boiler water pressure drops, it is used by the user to adjust the water level in the system. It is generally used to keep the pressure between 1 - 1.5 bar, which is the ideal operating pressure for most combi boilers.

In the field it is also known as the water top-up valve or water filling valve.

Compatibility

It is designed to be compatible with Bosch and Buderus combi boiler systems. Since different combi boiler models may have different types of filling taps, it is important to select the correct part according to the model and serial number.

Design Features

It is made of durable material and is long-lasting. It may have an ergonomic design for easy use. On some models, the water filling tap valve is opened and closed manually with a key or by screwing.

Installation and Use

It can be installed with simple hand tools; however, appropriate plumbing knowledge may be required to ensure watertightness and safety. To increase the boiler pressure, it is important to return the valve to the closed position after setting it to the open position.

Maintenance

Periodic maintenance is generally not required, but the water filling tap valve should be checked occasionally to ensure that it is working properly. Watch out for water leaks or valve blockage.

Safety Notes

Take care not to increase the water pressure too quickly, as this may damage the pipes or cause water leaks. If the pressure continues to drop rapidly after filling, this may indicate a leak or another problem, and a specialist should be consulted.

The water filling tap valve is a basic part of combi boiler use, and its correct use affects both the performance and the safety of the combi boiler. If you encounter any problems or have doubts about the system, it is best to contact an authorized service.
