Some radiators working, Some not.

[tuckjointer]

I'm a brickie and have been building an extension to my house. I plumbed in four new radiators straight from the 22mm flow and return. One up stairs, three down.
Now when I turn on the heating, all the original rads work (3 upstairs, 1 down). The new rad upstairs works, but the three new downstairs stay cold. All have water in them.
Any thoughts, I'm stumped. Bricklayers and water do not mix !!!

Thanks

Tuck
