I took the time yesterday to change the site tube on my steamer. I
also took the shut off valves apart to see if I could prevent them
from leaking around the valve stem. Doing this was a time consuming
chore that I imagine will need to be done again in the future. I
don’t understand the need for these shut off valves. When
maintaining the site tube a steamer can easily be drained. If the
site tube were to break under pressure, it would not be a smart idea
to try to shut these valves until all of the steam had been released.
I suppose the valves could be shut off in order to operate the
machine without a site tube until the place could be replaced however
a spare site tube is mandatory equipment in my shop.
I guess I have two questions. One, why the need for the shut off
valves at the site tube? Two is there any reason why the valve could
not simply be capped in order to prevent future maintenance issues?
