1. Trap Guard (TG): Smooth, flexible elastomerictrap seal device utilizes a normally closed
seal to prevent evaporation of the liquid trap seal and also protects against sewer gases
from backing up into the building or surrounding areas. The device opens when liquid
enters to allow drainage to flow through into the building drainage piping, and closes
when there is no drainage flow entering the drain. Provide on all floor, sink, and hub
drains connected to the sanitary sewer system or to other systems that may have sewer
gases present in the drainage system. The device must be selected and installed in strict
accordance with the manufacturer’s instructions and the requirements of the applicable
codes.
