With regards to that video ^^^ i didn't know it was a legal requirement to remove the filling loop.
Also,i thought i'd read somewhere you're supposed to bleed the rads in a certain order:?
errrmmm dunno :thinking:

I'm sure i saw a resident plumber lurking about here a while back.

it's been like that for years but not many people actually do it, it's to stop any contamination of the water main

it's always best to vent the rads upstairs first

Damn i just started d/stairs lol
I think some of my rads are full of gunk,they get cold at the bottom NOT the top.
OP never returned,hope it didn't blow up!
Put your clothes back on, the whistling should then stop.
if there is air in the pump you can get rid of it by just unscrewing the big screw at the front of the pump, let a bit of water piddle out along with the air. worth a go as it only takes a minute. i usually bleed rads downstairs and work up as upstairs will empty first so should be filled up last. (thats if your boiler is downstairs!)

op did you do this?
You vent radiators from downstairs first, not upstairs. Air is lighter than water and as such rises upstairs as you vent downstairs. Check the aav on the top of the boiler or it may be on the top of the pump.
