Hi gents and any lady's, I bought a wooster bosch set up from helplink about 18 months ago, and had no problems, the odd drop in preesure but nothing a quick top up couldn't fix. At the moment i'm topping up every couple of days and the pressure is on zero when the boiler hasn't kicked in then a slow rise to about one bar, any ideas?
Thanks Kev

The only way you can keep loosing pressure like that is when you have a leak. You cannot keep topping up a sealed system with mains water without loosing it somewhere.
The system should be pressurised to between1.7 & 2bar after all rads have been bled of air. Have a good look round the pump flanges, cylinder conns and rad valves. You must be loosing a couple of cups full by the sound of it.
