Hello
I have an intermittent leak in my Grant Vortex Pro 15/21 inside the case. Never very much water but the bottom of the case has sometimes 3mm of water. I have checked the flow and return connections but can't find any leak. The boiler is about five years old. Has anyone any ideas what may be causing this leak.
Thanks
