Think I have solved this. The T ball valves are not completely closing. Big job so will probably leave it till after Xmas

If you refer to my previous photo you will see that the flow meters (where i attach the tap hose) are at the top, and return vaves are at the bottom, which is where I am attaching the drain hose. I am off for a Christmas drink now - will post to any relies tomorrow.

Yes my flow meters are upper most.

Yes

No air bleeds anywhere. Thats the closest I can get for pics as the unvented cylinder is in the way.

Hose pipe in the top from tap - drain from bottom into bucket. as per this .

I shut down all loops ( Flow meter and pin valve) apart from number one. Waited for a steady flow of water then shut down that loop and opened the second loop and so on.

There is this - no idea what it is.

Today I will flush and refill then get back to you. There is no mixing pump and the manifolds dont have a an air vent. Hot water is supplied by a HeatRea Sadia and is pumped by a water pump. Thanks Johntheo5.

All the flow meters and return valves are exactly the same as the ones replaced

The manifold is a 3 loop Uponor Vario S. I have just installed 3 new flow meters and Pin return valves. I flushed and filled each loop one at a time, but the flow meters all show the red disc at zero. The water in the glass tubes all sit at around 2. The return pipes are 1 x warm 2 x coldish...

Exactly - i believe they are jammed.

Thanks for that but have seen that previously. Thats for balancing the system - I want to flush and fill system for which the lower valve needs to be fully open. When I turn the lower valve nothing happens at the flow meter at all.
