How to check if the ref. 129400015 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 129400015. 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 safety valve 129400015 resolves.
The safety valve releases pressure when the circuit exceeds its setting. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The valve does not open even though the pressure exceeds 3 bar.
Cause: If the seat is clogged with scale or the spring is not working, the valve may remain closed when it should open.
With the boiler cold, observe the pressure gauge while it heats up: if it exceeds 3 bar without the valve opening, it is a fault in the opening.
- 02
It opens at a pressure different from 3 bar, either before or after.
Cause: The internal spring loses tension over time, which affects the point at which the valve decides to open.
Note the exact pressure at which water is released several times: a clear and repeated deviation above 3 bar confirms the problem.
- 03
It continuously leaks from the discharge pipe with the circuit at normal pressure.
Cause: A worn seat or one with a trapped particle does not seal properly, even if the pressure is far from the set point.
Pull the bleed handle a couple of times: if the dripping doesn't stop afterwards, the seat is not sealing properly.
- 04
Water needs to be added to the circuit more often than usual without seeing a clear leak elsewhere.
Cause: A valve that does not close completely can lose water in a nearly imperceptible way, especially if the drip falls directly into the drain.
Follow the discharge pipe to the end: if it is damp or has recent limescale, the leak is coming from there.
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.
