This standard safety valve has been up-rated to 20-25 psi for us by MSS. Ideal if you are going to continue to fill your standard MSS/mamod boiler through the safety valve hole and need to remove the vale by hand whilst increasing the operating pressure and performance.

Very easy to replace, looking forward to testing it.

This simple upgrade allows the mamod to build up a little more pressure to allow it to pull a heavier train. If you upgrade the burner to the meths or gas you can take full advantage of the extra steam.
