thrush tees

K.Black

I need some info on the "thrush" tees I saw on the job today, like who makes them or are they even made anymore. If I had to guess I would say installed in the 60's and needs help (all the tee's were never adjusted and there are no dp ports). Any help would be great thanks and stay safe out there.

If those are the ones I've seen

they're basically Monoflo-type tees with adjustable diverters that work similar to circuit-setter valves.

Thrush was one of the first companies to market accelerated gravity hot-water heating, and if I remember correctly they also introduced the first hot-water circulator. Amtrol owned the company for the longest time but recently divested it. They probably have something on these old tees, go to their site
