came from different locations for the photo. One was inside; one was out in the truck? Thinking like a mystery writer here. Or maybe Mario had one in his armpit while he was setting up the camera? Hmmm.

I think the supply house guys

@ July 31, 2002 12:48 PM in vaporstat vs pressuretrol

are confused. Vaporstats belong on heating systems that are designed to operate on less than 1 psi, which would include just about every house in America.

if you add another radiator it has to have its own steam trap. You can't split into two and then bring them both back to the single trap because steam will short-circuit from one to the other up the return. That creates severe water hammer. It can be done, but you really need to have a steam guy look it over first. Got any good trap reps in the area?

@ July 31, 2002 7:31 AM in old school, newboilers

and you're adding a boiler feed pump you'll have to discharge from the vacuum pump into the boiler feed tank. From there, you'll need two motorized valves, one to each of the two boilers. Each boiler will have a pump controller that will open the motorized valve on the feed tank. An end switch in the motorized vavle will then turn on the feed pump. The motorized valves will keep the vacuum pump from sucking water out of the feed tank on start up. The equalizer would go from the boiler header (through a water seal and check valve) back to the vacuum return line. Its job is to break any naturally induced vacuum in the radiators (which forms when the steam condenses) that may be deeper than the vacuum formed by the pump. It's rare for that to happen and the equalizer is really a "just in case" thing. I've got a better description in all of this in Hot Tech Topics. It's in an article called, "The 25 Steps in the Repair of a Vacuum Steam System." Hope that helps!
