i think i have a open vented system. i drained the whole system first. before connecting the new radiators
then this morning i turned the water back on to gently fill it up.
let the radiators fill up til they started leaking out of the bleed valves.
(did i need to do anything else special? slightly worried about the tank that leads into the pump)
...and possibly this is where i went wrong: i thought you were supposed to bleed the pump with it switched on ( well thats what my brother said!)'
so the pump whirred lots...intemittently hissed , and dripped...but the water didn't flow, like they did out of the radiators. is that normal?
have i missed any steps? the pump is a lot nosier , and i'm worried there's still loads of air trapped in
