I have Glow Worm Flexicom which seems to have a few issues. It keeps losing water pressure over few weeks, and until a few days ago was making a loud bang noise when switching hot water/ central heating. I have one of those water tank systems. I called a gas engineer who has a quick look and asked me to see if I could identify a leak from the overflow pipe, and ask the downstairs neighbour about visible leaks and then call him back. I cannot see any leaks but the overflow is on an outdoor wall and I can barely see it, let alone put a plastic bag like it is suggested in some posts. Just after his visit the noise stopped and now I when I switch on the hot water the central heating comes on as well. Texted the guy but he never got back to me. I contacted another gas engineer who suggested I would be better off calling Glow Worm as they do a fixed price, and suggested that I may need to replace the diverter valve and probably the expansion vessel too (it was just a phone conversation). I am quite worried about the cost of all this, I thought an independent contractor may have been better, as Glow Worm do not include the expansion vessel in the fixed price. I am not sure whether to call a third engineer to at least have a proper diagnosis or just go with the Glow worm call...
