lossing pressure

[marlb]

Hi,

I have recently added some rads to my sealed central heating system and I have refilled the system and bled the radiators. The problem is that I am losing pressure. I have noticed that there is some water coming from the drain off pipe going outside of the house.

Is this my problem?

I put a bucket outside and under the drain pipe for about 3 hours and the bucket had an inch of water in it.

can anyone help

It could be dirt stopping the prv from closing properly.Open the prv and refill the system at the same time and it might flush any dirt out and solve the problem.

Thanks for the reply. I have just done what you suggested. Will leave bucket outside and see if it solves problem.

If it is still leaking what do you suggest?
