The other issue with mine is that the SV leaks so to build up a big head of steam, gotta have a big fire.
When the alcohol gets low, there is no turn the regulator off and let the steam build... On my Wilesco boilers, the SV allows me to build up pressure slowly...
Can the SV be unscrewed on the 16051? It would be nice to fit an adapter for a Wilesco SV or put in an original historic Märklin SV.
