6. If Overow is used (Figure 3) – Install the Overow Head in the sink. The modular
design of the waste drain allows the overow port on the Outlet to be positioned Left,
Right or Back. To change positions, remove the (4) cap screws with a 5/32”hex key
wrench and rotate the Outlet
to the desired position. If the
Outlet has been removed,
ensure the Valve Seal is either
in the Valve Body correctly
or installed on the Outlet lip
correctly. Install the (4) cap
screws and tighten. Measure
and cut the overow tube
to t into the Overow Head
and Overow Port on the
waste drain Outlet. Install the
Coupling Nuts and Seals on
the overow tube. Install the
overow tube and tighten the
connections.

1. Remove the Snap-in Strainer and unscrew the Sink Flange Assembly from the Waste
Drain Assembly. Apply a bead of Plumber’s Putty to the bottom of the Sink Flange
Assembly where it contacts the sink bowl. (Keep the Drain Guard installed in the Sink
Flange Assembly at all times. Remove it only when clog maintenance is needed and
install it again when nished).
2. Make sure the underside and inside mating surfaces of the sink bowl in the area of
the drain are clean.
3. Install the Waste Drain Assembly and Gasket from below the sink.
4. Install the Sink Flange Assembly thru the sink drain opening and screw it into the
Waste Drain Assembly below.
5. Before tightening, position the waste drain Handle to the desired location. Tighten
the Sink Flange Assembly securely with the Sink Flange Tool provided. (Figure 2)

7. Connect the drain line to the waste drain Outlet. If Outlet Adapters are used, seal all
threaded connections with pipe sealant.
8. Open and close the waste drain several times to check the operation. Check for
leaks.
Maintenance
Figure 4 shows a maintenance explosion of the Modular Waste Drain.
Under normal operation, the anticipated service parts of a B-3990 Series waste drain
are the Valve Body Assembly and/or Valve Body Seals. These parts can usually be ser-
viced or replaced without removing the waste drain from the sink or disconnecting the
drain line from the waste drain. The Valve Body Assembly is a non-serviceable part and
is simply replaced if repair is needed. The replacement Valve Body Assembly comes
with (2) Valve Body Seals. A Valve Body Seal Kit containing (2) seals is also available if
only seal replacement is needed.
Valve Body / Valve Seal replacement (Figure 4)
1. If Overow is used – Loosen the overow tube connection at the overow port on
the Outlet of the waste drain. It may not be necessary to remove the overow tube.
2. Open the waste drain valve by fully extending the Handle.
3. Loosen and unscrew the (2) Support Rods attached to the ends of the Handle. Push
them back into the Handle Guard to get them out of the way.
4. Remove the (4) cap screws that attach the Outlet to the waste drain assembly.
5. Pull the Outlet free from the waste drain assembly. There is usually enough play in
the drain line and overow tube to separate the Outlet from the drain assembly.
6. The Valve Body Assembly with the Handle will pull clear of the waste drain once
enough separation of the parts has occurred.

General Instructions
7. Remove the Valve Body Seals. These may be in the Valve Body Assembly or stuck on
the lips of the Drain Bell above or Outlet below.
8. If Valve Body Seal replacement is the only service being done, replace the old seals
with the new ones and reassemble in reverse order above. It works best to install the
new seals on the lips of the Drain Bell and Outlet rather that put them in the Valve
Body Assembly.
9. To replace the Valve Body Assembly, unscrew the Handle from the old Valve Body
Assembly and screw it on to the new one. The Valve Body Assembly needs to be
installed with the T&S logo visible from below. Install the new seals and assemble as in
step 8.
Clearing a clogged drain line thru a B-3990 Series waste drain
Eorts should be made to clear clogged drain lines thru clean-out ports in the drain
system. Should it become necessary to clear a clog thru the waste drain passage, ac-
cess can be done in the following way:
1. Close the waste drain to prevent loosing any loose objects.
2. Remove the Snap-in Strainer.
3. Remove the Drain Guard by loosening the (2) Vandal Resistant screws with the
Spanner Bit provided (the screws only need to be loosened and not removed). Rotate
the Drain Guard so the Screws align with the notches in the Flange. Lift out the Drain
Guard. For safety reasons, never put hands or ngers in the drain passage when
the Drain Guard is removed.
4. Perform the needed maintenance.
5. Close the waste drain and install the Drain Guard. Ensure the Drain Guard is installed
correctly and securely.
6. Install the Snap-in Strainer.
