I have been ....

making my own. Actually I had Lee @ www.earthlee.com make these up for me. She took down the specs and had them out w/in a week. Nice work. I add a 1.5" cap w/ a good hy-vent, add some screening inside and then go w/ a 1.5 x 1/2 coupling on the bottom. She will even paint them to you liking.

Hydronic Separator

I use them and Taco's version as well.  I quit doing primary secondary over 5 years ago when the light came on and I discovered the wonderful world of hydronic separators.  Saves a crap load of piping and labor.

There's never an argument on the spacing of closely spaced tees.
