I went back and looked at the construction video of Omingmak ,is it my imagination, or does the safety valve behave better then? Perhaps the difference is in more modern recording devices 😁

I think the valve may have behaved a little better when it was brand-new, but also it can be silenced by giving the stem a light tap. It pretty much stays steam-tight until the first time it pops off, and afterwards it doesn't seat fully unless one gives it the aforementioned little tap. After a while I couldn't be bothered so I just let it do what it wants now.

Hi Keith,
Have you tried descaling the valve?

You know, I hadn't thought of that! Good idea.

My RH Fowler less than 18 months old weeps steam from the valve from about 20 psi, even before it has blown off, so definitely seems to be a a RH problem
