6 OUT OF 8 RADIATORS WONT HEAT UP

[THELIVINGDAYLIGHTS1]

:oops: I PUT A DRILL THROUGH A CENTRAL HEATING PIPE, PLUMBER CAME OUT REPAIRED HOLE, BUT NOW 6 OUT OF THE 8 RADIATORS ARE STONE COLD, THE 2 THAT HEAT UP ARE THE 2 NEAREST TO THE BOILER. THE PLUMBER SAID SOMETHING ABOUT ALTERING A PORT VALVE. NO MATTER WHAT I TRY I CANNOT SEEM TO GET ANY HOT WATER THROUGH TO ANY OF THE OTHER RADIATORS, PLEASE HELP, NOBODY WILL COME OUT TILL TUESDAY AT THE EARLIEST

sounds like an airlock, try turning off the 2 radiators that do work, turn up pump speed.

If that doesn't work, you could try draining and re-filling.
