David Continuing saga! Having place this restrictor in the heather 4-way outlet. The heater only gets warm, not hot! So that is not correct. Have removed the restrictor completly to see what happens!

I think its the jiggle vales in the inley manifold. Howewer when I plow through the pipe, blocking the return pipe and expansion pipe I get air bubbles coming up in the expansion tank, That to me says it not blocked. But who knows!

Any further advice. Coming to the end of my tether now.
