I recently installed a PMR whistle on my vertical boiler. I had no problems the first run, it sprayed a little wet steam
at first, but then it whistled properly. Today, however, all it would do is spray water all over the place. I installed the
whistle as I have seen it installed on other PMR vertical boilers, so I don't think that's the problem. After I drained my
Boiler today the remaining water was a little "milky" looking. Could cleaning the boiler with vinegar solve my whistle-priming problems? I haven't done this for a while and I have never seen my water look milky before. Is this contamination making my boiler foam inside? Any help would be greatly appreciated.

Thanks;

I use tap water never had problems with it. It is possible that oil might have been drawn from the lubricator or engine when
the boiler cooled down it the vacuum might have drawn some in and last time I forgot to close the steam valve. I will wash out the boiler and then do a vinegar treatment then see what's up.

Yes it was the one I plated. The problem is not the pitch but the spraying. I'll get an occasional whistle that sounds
ok but mostly I get a fountain of wet steam spraying upward. When this clears I get a normal whistle tone. I'll
Try readjusting .
