How clean should CH be after flushing?

[dilalio]

Thanks for the reply @DP

Why do you think I will never be able to flush the system entirely,please?

The cleaner is only a 500 mL bottle and I checked out the size of all my radiators which totals 30 litres but obviously that would be plus pipework also
So if I said 5 L to fill all the pipework that would mean the cleaner only accounts for a 75th of the systems fluid

Surely refill bleed run and empty five times as I have now done it the water should be Running cleaner?

Remove rads.
Take them outside.
Turn em upside down.
Run a hose through them.
That's the only sure way for a diyer.

Something is reacting!
Do you have a water softener?

@dilalio nope, no water softener
Just 8 classic rads from Stelrad, an Adey professional 2 magnaclean and a Worcester greenstar 37CDI…. That’s it

Pipework?

@dilalio
All copper except 2 x 5m lengths (the flow & return) to a radiator at the end of my extension ( done by my builder 14 years ago)

The connections are Hep20 to this radiator
