What is the most cost effective way to measure temps/pressure on 3/4 and 1" HDPE pipe. I know about balancing valves but these are costly. I would like to have just a ball valve with a TP port or just a TP port with HDPE connections.
What have others used. I am not going to put this on every system, but will have a couple on HP coil in every system.
You don't need to give me prices , just appreciate ideas.
Thanks for feedback.
