Looks like we have a leak in the pipes under the dining room floor. Our apartment has a concrete slab foundation. And the pipes are embedded in it.
Yay 1970s (60s?) construction.
Fortunately (no really) the leak seems to be continuous, because that means it’s probably a supply line – which they can bypass. If it’s the drain line they’ll have to jackhammer out the dining room floor 😬
Also that means the carpet’s soaking in *clean* water.
Plumber’s coming tomorrow morning.
