boiler water line discovery

tariq

I installed a new mac donnell miller 47-2 water feeder yseterday on my boiler. And to my amazement, the water line did not jump around anymore. I just had to tell somebody! I have Dan's steam book and I've read it, several times. I think it amazing the way the 47-2 works. That big float inside balances everything. I have had other water feeders. A manual type and mac donnell miller no.101-A. They are not very good. The 47-2 makes the boiler run so much more efficient by keeping the water steady. It is not adding water to boiler yet. I am presently installing water line. I have been working on this water problem for awhile. But, now I know important it is to have a steady water line.I just wanted to share this --- comments?
