SANIT Filling Mechanism For Biasi M295.28CM And MURA 24E
If you cannot fill the heating circuit or notice a continuous water leak, you may need the SANIT filling mechanism for BIASI M295.28CM and MURA 24E. This part acts like a valve that allows you to replenish water in the circuit, ensuring that the pressure is maintained at appropriate levels. In case of a fault, you could experience pressure issues, which will affect the operation of your boiler. This mechanism is compatible with several boilers, including BIASI M295.28CM and MURA 24E, as well as other models from GMA, MIDAS, and MINOX. It is recommended to replace it when it shows leaks or does not function properly.

How to check if it is the part 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 —. If it is not visible, do not identify the part by 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 filling valve 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
Water is leaking right in the area of the filling valve, even though the rest of the circuit is fine.
Cause: The gasket or the internal mechanism of the valve loses tightness due to use and the continuous passage of pressurized water.
Gently tighten the inlet and outlet fitting; sometimes the dripping comes from a loose joint and not from the valve itself.
- 02
You open the filling valve and the circuit pressure does not increase, it stays the same.
Cause: The internal mechanism does not allow mains water to pass into the circuit, due to a blockage or a fault in the internal valve of the key.
Check that the main water supply shut-off valve is open and that there is no clogged pre-filter before assuming the filling valve is faulty.
- 03
After refilling, you can't completely close the valve and water keeps flowing.
Cause: The internal sealing seat wears out or gets limescale deposits and no longer seals completely.
Turn the key slowly to the stop and check if the dripping stops completely or just reduces; if it only reduces, confirm the wear of the seal.
- 04
The pressure gradually increases without you having touched the valve.
Cause: A faulty internal closure allows a small continuous flow from the network into the circuit, even though it appears to be closed.
Close the mains water inlet valve to the circuit for a few hours and observe if the boiler pressure continues to rise; if it keeps rising, confirm the internal leak.
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.
