I own a terraced house, the boiler is upstairs, the one Rad with a drain fitting is a step up from the others downstairs so im a bit concerned that the 3 others downstairs won't empty. Can I turn off gas to boiler, leave the cold water flow to the boiler on and attach a hose to the Rad drain fitting, wouldnt that literally feed clean water through the system and then I can run it until clear , a lot of advice says to turn off all water supply to boiler and drain system I'm assuming there is a reason for this, however rather than emptying system wondered if I could do it this way and get water pressure through system and then bleed radiators. Thanks in advance, happy Christmas.
