I am wondering if the problem may be due to scaling as I live in Oxford with very hard water. If the pump needs descaling, how do I do it? Thank you qim

Thanks, mate. Will try in the morning. Hope no need for Fire brigade! qim

Grundfoss Pump probably stuck. I saw this link and would like to try //www.diynot.com/forums/viewtopic.php?t=103104 but I'm afraid that on takinbg screw out a lot of water will run out of boiler. Is that not so? Thank you qim
