Warm spot on the floor in a house under twenty-five years old
I Like To Fix
PEX run under slab. The material is durable but the slab is unforgiving — a leak tracks laterally and shows as a warm patch well away from the failure. Leak locate first, always, before any concrete comes up.
This is most common in homes built since 2000. PEX on slab, 200 amp service, builder-grade equipment that reaches end of life across a whole street at once.
