water hammer

nicholas bonham-carter

has the pressure suddenly changed due to a clogged pigtail?
how do you know that the vents are o.k? could they be clogged too?
i wonder if there are fungial growths in boilers, gathering strength in the summer to be flung out in early winter, plugging things up??--nbc

When does the water hammer occur? Beginning of the steam cycle? Middle?, End?
