How to replace the Safety Ring

Replacing the safety ring is a simple process. With the right tools, it shouldn’t take more than a minute.

The safety ring is a fail-safe device which will safely depressurise the machine if it’s overheated. You’ll know you need to replace the safety ring if you notice water leaking from a small hole on the side of the ring.

Tools and parts required

• A replacement safety ring (and options replacement seals, if needed)
• A 13mm spanner (a.k.a. wrench)

Instructions

1. Remove the safety valve form the side of the boiler, by unscrewing the whole valve. You may be able to do this with your fingers. If not, use a 13mm spanner (wrench), to loosen it. You want to place your spanner around the nut – that’s the part of the valve that has flat sides. In the image above it’s directly above the gold coloured safety ring, it’s on the outside of the boiler.
2. Remove the gold coloured safety ring, by pulling it off the safety valve. The two red seals will come off with it.
3. Push the new safety ring into place, with one red seal located on each side of the safety ring.
4. Screw the new valve into the threaded hole on the side of the boiler. Screw it in hand tight, then use a 13 mm spanner to tighten so there is “metal on metal” contact between the safety ring and the boiler. You won’t need to tighten it very hard, the thing to feel for is a sudden increase in resistance when screwing it in (that’s when you get metal metal contact).

That’s it! If you have any questions, please either add a comment below, or contact support.
