Hi
I have now decided to retrofit the new SMA valve. However, I don't want to screw it directly into the boiler because I don't want to accidentally damage the female thread of the boiler. That's why I disassembled the old valve and used the first tube to fix the new SMA valve in it. Obviously, the heat at that point is still sufficient to close the valve in time. Nevertheless, the temperature will be lower than directly at the boiler. This may have a positive effect on the durability. We will see how it goes.

Thanks for posting this. Looks good. It may be the best solution for me because I have an older GS/3 with chassis supports that are turned 90-degrees compared with the supports used in later models. That brings the edge of the support closer to the vacuum breaker, which could make it difficult to get a gradual curve in the plastic tube.

Do let us know if the new position causes any issues with the breaker closing.
