Hey, I've recently moved into a new home, which has a Worcester 24i Junior Combi Boiler. The pressure is low, and needs increasing asap. I've done a bit of research on here, and found out that if I clip the bottom off of the boiler there is a key underneath, etc. I cannot find anywhere at all where this key would fit, nor any kind of filling loop. It seems to me that it might be the case that I need to order an integral charging link (part 87161045920) - that this would then connect onto the underside of the boiler, and the key that I already have would then fit into this and allow me to increase the pressure. Could anybody please advise me as to whether this would definitely solve my problems? Thanks in advance......
