Watts TD-300 installs during new construction or in existing floors
Elevator/Threshold channels should sit slightly below flooring to ensure a smooth
transition from one area to another when the grate is installed. The grate should
match up flush with the floors and create a safe level transition.
Installing the channel
Leader drain pipes must be installed to connect with the center or end drain outlet
in order to divert and filter excess water.
Leader drain pipes are used to connect the drain to the intended drain lines. These
pipes should be in place and designed to connect to the drain outlet whether it is
located in the center or in the ends of the channel.
The drain is designed to fit into "boxed-out" areas in both new construction and in
existing floors.
Wood is used to create a form or boxed-out area to hold the channel.
Create a solid level base for the channel. This may be done with concrete or other
materials. Use a level to ensure that the channel is level and will properly meet
floor level when grate is installed.
Form the approach to the entrance by laying the required sub-base up to the
channel, leaving sufficient space for the surface finish. Any final adjustments
should be made at this time.
Anchor straps may be screwed into existing concrete or flooring, or screwed into
wood forms to hold the channel steady during a concrete pour.
Concrete may be poured around the channel.
