I have a H B Smith steam boiler in my townhouse. Last year the feed water control (McDonnell #67) was replaced. I have noticed that this year the water level is only 2 inches above the low end of the water glass, the automatic feed will go on if I drain water from the boiler but only refills to this low level. The water feed also seems to come on more often but only for a short time. What is wrong?
