OT Construction Plumbing Question

[nostradamus]

I was looking at a condo and a neighbor there told me a funny story. She said the upstairs units (it is a 2-story building) water heater pipes go out from the water heater, down through the wall, into and across the slab under the downstairs unit, then up another wall and back into the upstairs unit. She knew this because there was a slab leak in one of those pipes.

Why would the hot water pipe leave the upstairs unit and go down into the downstairs slab before going back up to where it’s used? It seems risky and leak-prone, as well as creating extra wait time for hot water.

Anyone know why this would be done?

Maybe the plumbing was originally set up for a common water heater? Is it a conversion? Maybe it still is on a common water heater? Sounds like it isn’t and every unit has a private water heater now. Other than that nothing comes to mind as to why it would have such a setup.

No, they were original condos without anything shared except walls and vent shafts. I guess this is just a mystery case.

Thanks for your input! I thought there might be some lame construction ordinance requiring such silliness. I’m glad there isn’t.
