Would this be beneficial?
Some of the radiators in our 1 pipe steam system in our 32 unit apt building have been removed and capped off over the years for various reasons, would it be beneficial to uncap these lines and install some vents? Most of the removed radiators are on the 3rd (top) floor, so it seems logical to me that installing some gorton #1's on these lines would be beneficial, so as to speed up the air removal. Some of them we would want to install on a 7-8 foot riser to prevent a tripping hazard, as well as protect people from a potential failed vent leaking steam, and strap them to the wall so they couldn't be broken over by vandals.
If it is beneficial, would gorton #1's be more beneficial for these locations, or would hoffman 76's be more ideal, since the 76 wont break and allow air to be sucked back through the steam feed pipes like the gortons will?
I've been busy building 1" manifolds for the main vents on the dry return, got two returns done tonight, got two more to do tomorrow, building them to be expandable via ending with a plugged T, allowing the plug to be removed and another nipple and tee added as we can afford to buy gorton #2's for it. I'm hoping to get 6 #2's and a brass swing valve vacuum breaker on each dry return by the time its all said and done, but since we're going to be starting with one each added every couple months, it'll take awhile.
