Hello to all you super people, well I have a bit of a predicament, I am in the process of changing a radiator in the upstairs bathroom for a towel radiator. I am scared to death to drain the system as we have been here 18 years and its never been done the system consists of a glowworm boiler, hot water storage tank in the bath room, with a feeder tank above that, then a header tank in the loft. I have heard of way were you don’t have to drain down the system by doing the following put a cork in the header tank feed pipe also in the breather pipe that’s above the header tank thus causing a vacuum letting you work on the system with out water coming out the system….? Can any one verify but if I have to drain the system I have two pipes very near the boiler with drain taps on them would one be for up stairs one for down ?
