The boiler is a potterton promax sl heat bolier.
When I put both CH/HT.after about 1/2hrs up in the airing cupboard loud banging comes from the pipe that the pump is connected onto the pipe.
And when I run the hot water through the tap a loud noise either comes from the boiler or the pipe work. The noise is exactly like a toilet when flushed and the water goes. Well that was the noise. I heard when I ran the water from the tap. And also my bolier goes low and high sometimes is this losseing pressure?? is this safe to use??
