Low pressure on combi boiler?

I recently took a radiator off the wall to decorate. since then we have lost pressure in the boiler on a regualr basis. We replaced the filler loop so we could put pressure back into the system, but now we have a leak from the boiler to an over flow pipe that runs out side of the house. we have measured the amount of water we are losing and its about 1 cup full over a period of about 7-10 days. Therefore we need to put pressure back in, every week or so. Is there anything we could do?? (We have flushed the system using the 3 bar knob, to try to dislodge any dirt/grime several times, but although this has reduced the leak, it hasnt solved it!

Any ideas!?

There are two things you can try, hit the red know (PRV) to try an re-seat the valve, or open it fully, let the pressure drop to 0bar, and remov the PRV, clean it and lub it with none setting silcome grease. To remove the PRV, get a pair of grips on the black ring that sits behind the RED PRV. You didn't say which boiler you have, but I assume the PRV is accessable, and RED. Good Look

if you opened the pressure relief valve then there will be dirt in the washer you will have to remove the inside of the valve and clean both inside the valve and the seating off the valve
