How to check if the part number BI1141500 is the one for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference BI1141500. If it is not visible, do not identify the part from its shape alone.
- 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 BI1141500 three-way valve resolves.
The 3-way valve diverts water between heating and domestic hot water. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The valve gets stuck after the summer: when turning the heating back on, it takes time to distribute the water properly between the two circuits.
Cause: Months without movement allow lime and debris from the circuit to clog the brass shutter from the inside.
Force several heating and domestic hot water cycles in succession when restarting the season, and check if the distribution improves with use before replacing it.
- 02
The domestic hot water comes out with less pressure or is interrupted when there is also a demand for heating.
Cause: The internal shutter, worn from use, does not completely close the heating flow when it should prioritize the domestic hot water.
Manually turn off the heating and check if the domestic hot water flow improves; if it does, the problem lies in the distribution of the valve.
- 03
Dark residue or rust comes out of the hot water tap when the boiler has been idle for a while.
Cause: The brass body and its joints wear out over the years and release particles into the circuit.
Let the water run for a couple of minutes after a long period of inactivity before assuming that the gas valve is broken.
- 04
You notice a slow drip in the area where the gas valve connects to the pipes, more visible when the boiler has been running for a while.
Cause: The sealing gaskets give way due to thermal expansion after years of service.
Carefully tighten the nearby fittings before declaring the leak safe, as sometimes the dripping comes from a joint and not from the body of the valve.
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.
