I've already got the radiator off but need to drain the whole system to cut into the pipework to make some adjustments but there is no drain valve in sight. The only solution seems to be to drain it from the boiler - a Vaillant ecotech pro 28.

Thanks. It's a Vaillant Ecotech Pro 28.

I need to alter some pipework on the central heating system. The boiler is a Vallaint combi but there is no drain valve on the system at all. How can this be done? the pipework to be altered is upstairs.
