Hot water issues

Hi, I first noticed when running the hot tap on the bath the tap in the kitchen would start dripping, but stop immediately when the bath tap was turned off. Then started noticing a groaning noise when using hot water on any tap, now the shower will only run hot, no matter where you turn it. Not sure if this is all related or separate issues?

"Hi, thanks for your message. Yes, these issues do sound connected and are likely related to the hot water system or shower mixer. The kitchen tap dripping when the bath hot tap is used, the groaning noise with hot water, and the shower only running hot could all be caused by pressure problems, a faulty valve, or a failed shower cartridge/mixing valve. It may also involve the hot water cylinder, expansion vessel, pressure reducing valve, or a partially blocked mixer tap. We’d recommend having the system checked properly to identify the exact fault before replacing any parts. If possible, please send a photo of the shower controls, let us know whether you have a combi boiler or hot water cylinder, and mention any recent plumbing work so we can advise further before arranging a visit.

It is possible that a loose pipe joint or airlock issues may be contributing to the problem.."
