How to check if ref. S1007000 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.

1. Find the reference printed on the installed part and check whether it matches the catalogue reference S1007000. If it is not visible, do not identify the part from its shape alone.
2. Check the full boiler model on its data plate and look for it in the model associations on this page.
3. Compare the connections and physical body with the original part before installation.
4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.

Symptoms and faults that the filling valve S1007000 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

  A drop of water comes out from the body of the tap or from the control when filling.

  Cause: The seals of the valve wear out with use and allow water to pass when operated.

  Dry the area well before opening the valve and check if the drop is coming from the body or from the connection thread to the circuit.

• 02

  After filling to the correct pressure, it drops on its own again in a short time.

  Cause: If the non-return valve does not seal, water can flow back into the network instead of remaining in the circuit.

  Fill it, close the valve, and monitor the pressure gauge for the first 10-15 minutes; a rapid drop indicates that this part may be the issue.

• 03

  Water is continuously dripping from the tap even when it is fully closed.

  Cause: The closing seat is worn or has a trapped particle and does not close completely.

  Tighten the knob a little more without forcing it and check if the dripping stops; if it doesn't stop, the wear is confirmed.

• 04

  It is necessary to refill the pressure more frequently than normal without seeing any visible leaks.

  Cause: A faulty closure in the valve allows water to leak into the network gradually even when it is closed.

  Close the valve completely and monitor the pressure gauge without touching anything for a few hours; if it continues to drop, suspect this part.

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.
