How to bleed - water feed on return side.

edited November 2018 in Gas Heating
Hi there. I have a three zone radiant heating system with 3 circulators. The water feed is piped directly to the return line on one of the zones. If I try to isolate any of the other zones - how do I get the water to push out the air if the water feed is only connected to the first zone? Please see the pic - I hope this question is clear. C is for circulator, V is for valve, P is for purge station. The V’s on the supply side on right side top are flow valves.

    Do I presume the Vs in the pipes are valves, and the little circles pumps? Or? And then the next question is -- where are there any drains?

    Are there any shut off valves and hose bib looking things. I personally think that is a wonderful drawing but a picture would be better.
