My boiler won't hold its pressure unless I leave the cold water refil open to keep topping it up I cheacked the pipe work to the rads and can't find any leaks what else could it be?

Hi - this has been discussed many times in the last few weeks - have a scan around the plumbing forum and you will find similar problems with advice.

Leaving the filling loop open is NOT a solution! I guess your lucky your mains pressure is low!

Check the pressure relief pipe that goes through the wall, is it dripping/running when the boilers on.

Keep topping it up with fresh water will kill the boiler.
