bleeding problem

[sam1670]

hi there agian so i finally got the trv's fitted couple of hiccups yesterday. however im having trouble bleeding system. i emptied the whole system and seems to not be filing up. where do i start the refill process?
do i try running the system with pump or will it damage it or is it a case of waiting for the water to slowly drian through system

Have you checked your header tank? I've no idea what type of system you have. Is it sealed or open vented? Do not run the pump dry!

i have the cold water feed tank in the loft (f/e tank) a vented system.
im back to work now and left my wife bleeding it.
the system seems to be filling with water slowly now taken a day to fill the bottom rads, must be a mega air lock some where

You should stick with one post or we don't know whats going on.
More likely a blocked cold feed.
You need to check the cold feed where it joins the main system more likely full of crud thats restricting flow from f/e to system.

Try running a magnet around where the cold feed joins the system pipework if it sticks the pipeworks blocked/restricted with crud.
