Acidic condensate: drainage, trap and neutralization
Coordinate boiler/furnace/heat-pump condensate with durable disposal: material, slope, trap, air gap, freezing and neutralization when condensate is corrosive.
VERT / GREEN
Identify which appliance produces condensate and where it actually discharges.
JAUNE / YELLOW
A drain that leaks, freezes, blocks or traps poorly can cause damage, odours and equipment shutdown.
ROUGE / RED
Corrosive condensate discharged onto vulnerable material or improvised sanitary connection: correct the route and required neutralization.
Quick triage
What the professional checks
The technician/plumber checks condensate type, pH, neutralizer, trap, material, slope, air gap, discharge and freezing.
