In-floor heat
Two different waters can wet the same floor. Name which.
Glycol or heating water in a slab is not the same system as domestic copper. The repair, the shutoff, and the insurer questions all change.
Ask whether the building has in-floor heat in that room.
If no, stop guessing glycol.
Colour, smell, and which system lost pressure.
Heating loops have gauges. Domestic meters are different dials. Read the one that moved.
Do not open the slab to ‘see the colour’.
Investigation should use the mechanical room and surface clues first.
Questions people ask
Is a warm wet floor always in-floor heat?
No. A domestic hot line can warm a floor too.
Can ProShield isolate a heating loop?
Only with building authority and a reason. Heating plants are not occupant valves.
