Welcome! Here are the website rules, as well as some tips for using this forum.
This is something I have never seen before. I traveled up to Philadelphia from DC today to take a look at a customer’s steam system. 167 unit apartment building, 8 stories.
There is what appears to be a thermostatic steam trap manifold at the feedwater tank. There are three returns coming to the tank, as well as two pumped returns, all coming to this receiver.
Any idea what purpose it served? The mains are dripped at the ends and in the middle at intervals of about 100 feet. All that is ok. But someone decided to put another steam trap after the drips from the ends. Those tie into the main returns, which are trapped again at the tank, then trapped again at this manifold. (Quadruple trapped....)
This is a seriously knuckleheaded system. Pretty much every “do not” has been done.
I’ll be making a post about it tonight probably. I’m sure some of you will get some enjoyment from it. Lol
Never stop learning.
