SANIT Filling Mechanism For Biasi M295.28CM And MURA 24E

If you cannot fill the heating circuit or notice a continuous water leak, a technical diagnosis must confirm if you need the SANIT filling mechanism for BIASI M295.28CM and MURA 24E. This part acts like a valve that allows water to be replenished in the circuit, ensuring that the pressure is maintained at adequate levels. In case of a fault, you may 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. A technician must confirm through diagnosis whether it needs to be replaced when it shows leaks or does not function properly.

Guide

How to check if it 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 —. 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.

Diagnosis and fault codes

Symptoms that require diagnosis in the filling valve

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.
