TRV4 Crackling as it closes.

You could have isolated the boler too!

Of course I really dont know why you choose to do that!

The TRVs work best on the flow!

By partially draining you have now introduced more air. Back to the beginning.

Calmag is a cheap inhibitor!

You probably dont need to add any more.
