My partner has a hot water tank in a cupboard next to the on-suite shower, there is a problem with the hot water; sometimes there’s nothing and sometimes it will come out but with low pressure, everywhere else in the house is fine, the pipes for the shower go up into the loft and back down so I think the water is flowing back into the tank leaving just air in the pipe.
Is there anything I can do to solve this?

Thanks
