I’ve a bit of DIY coming up which will involve moving a radiator back couple of feet (made bathroom smaller last year, which means we can make mini-verses’ bedroom a bit bigger).
I’m not 100% clear on what I need to do to stop water pouring out of the radiator pipes when they’re cut through…
Under the combi-boiler I have;
– 2 isolator taps (in and out of the boiler presumably), I use them when emptying the Fernox sludge collector.
– a stop tap that I use to top the system up if pressure is low (usually following emptying the sludge collector)
Do I need to drain the whole upstairs heating system, or can I just isolate the boiler with the taps and rely on the vacuum in the system to keep the water in place?
Any useful guides on-line?
