Hot Water Plumbing Problems

[mariyasmth11]

Hey there.
So we have an old home (1902) that is 3 stories.
We currently have a tenant in our ground floor apartment. She just informed me that she is unable to get the hot water to come out of the bathroom sink tap.
She could let it run and run and it will not get hot at the sink tap.
Her kitchen sink tap works fine.
Our kitchen sink tap works fine.
Our 3rd floor bathroom sink gets hot pretty quickly but
our 2nd floor bathroom sink tap has the same problem that out tenant does...
Our 2nd floor bathroom sink hot water has NEVER gotten hot (unless I take a shower in there beforehand) and we've just learned to live with it, since our primary bathroom is on the 3rd floor...
Anyway, this is a new problem ( we think) for our ground floor bathroom sink as our previous two tenants never mentioned it.

We have a tank (blech) water heater 80 gal on the ground level of the house, so her bathroom is actually the closest to the source of hot water.

We can't figure this out.

Any ideas oh plumbing gifted folks out there? Thanks!

umm... weird place to post your question. This is a skyscraper-related forum.

Well, since it is engineering related...

I do plumbing for a living, and I don't have a clue what the problem could be. You really need to call a plumber and have him/her trace it down in your house. Pretty strange that you would get hot from your lav/sink after running the shower. Sounds like the sort of thing that only happens when fixtures are too far away from the heating source, where you would need a recirc line. But your fixtures are close, so I have no idea.
