Son is in first year uni, in Halls. His hall is divided into corridors and flats which each share a bathroom and kitchen. His flat is tucked in an annex on the third floor and only has 3 occupied rooms. He recently told me that their 'hot' water is usually only very luke warm, i.e. only very occasionally and randomly being warm enough to have a decent hot shower. He said his flatmate(s) have previously reported it but it wasn't fixed so they've just been living with it. He thinks other parts of the hall do have constant hot water. I've obviously encouraged him to report it again, but what are reasonable expectations for hot water? Aibu to think it should be permanently hot, not just intermittently?
(For context, the reason he mentioned it now is because we'd been trying to work out why he's had 3 stomach bugs in the last few weeks - we now suspect it's at least partly to do with not being able to wash hands/dishes in hot water.)
