3 Bar Safety Valve Saunier Duval Metallic ThemaClassic C 25 E Ref. S1006700
The 3 bar metal safety valve from Saunier Duval is used in the ThemaClassic range of boilers, such as the ThemaClassic C 25 E model. Its function is to release water from the circuit if the pressure exceeds 3 bar, thus preventing damage to the system. If the valve fails, you will notice that it drips continuously or does not discharge when necessary. This model is compatible with several Saunier Duval boilers, such as the ThemaClassic F24E, C24E, and F25E, among others. It should be replaced when it shows leaks or does not function properly.

How to check if ref. S1006700 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 S1006700. 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 S1006700 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 continuously drips water from the outlet, even though the boiler has been turned off for hours.
Cause: The seat does not close completely, usually due to lime scale or a particle lodged between the shutter and the seat.
Pull the bleed lever a couple of times to try to flush out the dirt and check if the dripping stops before replacing it.
- 02
The valve releases water as soon as the boiler starts heating, even though the pressure seems normal when cold.
Cause: An expansion vessel without charge does not absorb the expansion of the water, and the pressure rises quickly until the valve activates.
Measure the pre-charge of the expansion vessel with the installation cold before declaring the valve faulty.
- 03
The circuit needs to be refilled frequently, and there are no visible leaks in the rest of the installation.
Cause: A slow drip from the valve, even if unnoticed, gradually reduces the pressure in the circuit over the days.
Place dry paper under the discharge outlet for a day and check if it gets damp before looking for the leak elsewhere.
- 04
You can see lime deposits or dry white stains next to the valve, on the floor, or on the boiler itself.
Cause: They are marks from previous drips that have already dried, indicating that the valve has not been fully closing for some time.
Check if the stains coincide with the pressure spikes when heating before assuming the valve is broken.
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.
