When the pressure of your combi drops below 1bar, it ensures that the water of the combi is completed. However, filling taps may differ according to combi brands and models. These parts are not standard for every boiler.
Why Does the Fill Tap Fail?
The filler cock is a precision part. The main reason for the failure of the filling cock is user intervention. The part must be opened carefully to flood the boiler. If it is tried to be opened with a hard intervention, the part may break. In addition, if there is a problem of constant pressure drop in the combi and you need to constantly press water, it may lick because you will use the part frequently, and for this reason, it may not be closed by malfunctioning.
What Problems Occur When the Filler Tap Fails?
When this faucet fails, a pressure rise problem occurs first in the boiler. Because the pressure continues to rise on its own due to component failure. If the pressure rises and exceeds 2.5 or 3 bars, then the problem of water flow also occurs.
