Drain Valve Biasi Ref. BI1181501
Biasi drain valve with reference BI1181501. The spare parts list for Rinnova Cond Plus identifies it as the circuit drain tap; it is not the valve that replenishes water to increase pressure. Before purchasing, confirm the reference and the position of the part in the breakdown of your model. A leak requires technical diagnosis to distinguish between a problem with the valve, its seals, or a nearby connection.

How to check if ref. BI1181501 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference BI1181501. 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 that require diagnosis in the BI1181501 drain valves
Common symptoms and faults
- 01
There is a water leak near the drain point.
Cause: It may come from the valve closure, a gasket, or a nearby connection; it does not by itself indicate that the valve is faulty.
Inform the technician where the moisture appears and the model of the equipment. Do not manipulate the hot or pressurized circuit.
- 02
The valve handle is damaged or cannot be moved.
Cause: It is necessary to check the condition of the control and the mechanism before determining the repair.
Do not force the control or try to drain the circuit to check it; request a technical inspection.
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.
