Yes, some plants repack all steam valves as a matter of preventative maintenance. Steam can be very cagey depending upon pressures used for the specific application and the metal gaskets some valves use can require a lot of experience to properly install. But the average home sized boiler, go after the ones that are condensing and dripping. The stems get eroded over time and that can be a real pain. By high pressure I generally mean anything over 200psi, something you don't find in your average home. If that is your question?

    I just repacked 2 valves, one had a little water coming out and the other had water but evaporated quickly. How can i test the other for leaks. I dont see anything wrong with them visabily but can it still leak steam without seeing it?
