Volatile liquid traps (heating oil traps) are the ideal drain for the boiler room in the basement. The surface water is collected through the slotted polymer cover and discharged to the sewer. If volatile liquids such as oil get into the drain, a float switch ensures that the soiled wastewater cannot enter the sewage system.
The volatile liquid trap (heating oil trap) is optionally equipped with a type 5 twin flap backwater valve and prevents wastewater flowing back from the sewer from getting into the basement. There are special upper sections available as accessories for installation in impermeable concrete, for the shallow-bed method and as a waterproofing layer against water load. There is also a rat protection flap made of stainless steel available as an accessory.
