draining system

help!

im new to plumbing so be easy on me!

i succesfully replaced a bedroom radiator by isolating the old one at the valves and replaced with a new one.

the problem now is that a leak has sprung from below the valve on the water intake side. ie the valve has become loose from the pipe and needs retightening or replacing.

im currently draining the system so am able to access the pipework water free. however it has currently taken almost 4 hours.

i turned the water supply off at the mains so there is no water coming into the house. i have no water tanks. i have a boilermate system.

all i want to do is get the water level low enough (ie below 1st floor level) to replace the valve in the bedroom, and i am still draining the system after 4 hours, and 10 buckets later!! should it take this long? no more water is being fed into the boilermate etc.

help

Hi,

Yes I'm afraid there is a LOT of water to come out. All the water in the Boilermate needs to be drained. Typically 200 litres or so.
