Performance Requirements for Barrier Type Floor Drain Trap Seal Protection
Devices
This new ASSE Standard #1072 introduces an alternative method of protecting
floor drain water trap seals- Barrier-Type Floor Drain Trap Seal Devices.
Because this barrier method does not automatically and periodically provide
water to replenish the trap seal, it must provide a barrier on the inlet
side of the trap seal that will minimize its evaporation caused by the
ambient air on the building side of the trap. This barrier must also provide
adequate drainage capabilities required for the floor drain’s intended use
as determined by its design, size, and installation location.
While developing
the performance requirements and tests for these devices, certain adverse
conditions were taken into consideration. These are the introduction of
fouling substances such as dirt/sand, floor wax or grease directly into the
device. In addition drainage requirements to accommodate infrequent, and
unusually sizeable, water flows caused by water line breaks, fixture
overflows or backflow preventer discharges are provided. Tests are included
to confirm that devices submitted for approval provide the performance
