What determines it is not the boiler model, but the reference printed on the part you already have installed.

- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the filling valve BI1181503 resolves.
The filling valve allows water to refill the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The faucet drips even when it's closed, and there is a puddle under the boiler.
Cause: The brass fitting or the rubber sleeve do not seal properly and allow water to pass through even when the valve is closed.
Check if the dripping comes from the rubber sleeve or from the fitting thread before considering the part damaged; sometimes it is only necessary to tighten the joint.
- 02
I can't increase the pressure in the circuit even when I open the valve.
Cause: The internal passage of the valve is blocked by scale or dirt and does not allow the flow of mains water.
Open the valve and check if water flows normally from the other end before replacing it.
- 03
It is difficult to turn the key; it is stiff or jammed.
Cause: The internal mechanism has become stuck due to lack of use or due to the accumulation of limescale on the stem.
Try to move it carefully in both directions; if it doesn't move, do not force it to avoid breaking the brass fitting.
- 04
After filling, the pressure continues to rise on its own over time.
Cause: The valve does not close completely and allows a continuous flow of mains water into the circuit.
Close it completely and observe the manometer for a couple of hours; if the pressure continues to rise, confirm that the problem is the valve and not another element of the filling circuit.
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
