Vaillant VMW/VMI Non-Return Filling Key Ref. 014674
Unidentified part with certainty: the datasheet classifies it as a safety valve, but the title published today in the catalog also calls it a filling valve and a check valve. The three names do not match, and there is no information on the part to confirm which is correct. The body is made of brass, without any visible markings or brand. Compatible with Vaillant boilers from the VMI and VMW 280-282 series.

How to check if ref. 014674 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.
- Locate the reference printed on the body of the safety valve you have installed: it should indicate 014674.
- Check your boiler model on the nameplate and look for it in the list of compatible models on this page.
- Compare the connections and the body with the original part before installing.
- If you have any doubts, send us a photo of the screen printing via WhatsApp and we'll confirm it for you before you purchase.
Symptoms and faults resolved by safety valve 014674
The safety valve releases pressure when the circuit exceeds its set point. These are the typical symptoms and what to do:
The pressure in the circuit gradually decreases, and it needs to be refilled every week.
Cause: If this part acts as a filling key or a non-return valve and doesn't seal, it will let water escape from the circuit even when closed.
Close the boiler's main filling valve and check if the pressure remains stable for a few hours before confirming this part as the cause.
Water is leaking right in this area of the circuit, near the boiler.
Cause: A worn seat, regardless of which of the three functions listed in the catalog it serves (filling, non-return, or safety), allows water to pass continuously.
Dry the area thoroughly and locate the exact point of the leak before ordering the spare part, to confirm that it is this piece and not a nearby gasket.
It leaks more right when the boiler has been heating strongly for a while.
Cause: If its function is for safety, it releases water when the circuit pressure rises with the temperature.
Check if the dripping coincides with the hottest moment and if the pressure gauge rises before dripping; this way you'll know if the problem is pressure-related and not just the 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.
