Application

The Model 404 and 405-Series drain pumps are designed for use
in gray wastewater applications. They will handle small debris and
solids, such as laundry lint (up to 3/8"), associated with normal
gray water drainage from a sink. Larger solids should be kept out
of the pump system. The 405-Series is designed for commercial
applications where higher temperature drain water (up to 180°F)
may be used.

Installation

Inlet
13-11/16" The drain pump has two available ports: one on the top, the other
[34.7cm]
on the side. Either can be used as a vent or inlet. Using the
appropriate piping (1-1/2" on 404 and 404CV models and 2" on
404L and all 405 models), connect the fixture (i.e., laundry tub,
basement sink, washing machine) to the pump. Refer to Figure 4
for a typical installation.
A trap shall be used between the fixture and pump; a flange type
is recommended. Hand-tighten trap to pump.

Discharge
Install a union just above the pump to facilitate removal, if
necessary, for cleaning or service. Install a check valve (not
included except for CV models listed below) just above the union
12-5/8"
and as close to the pump as possible to prevent the backflow of
[32.07cm]
water after each pump cycle.
Check Valve for CV Models
Models 404/CV, 404CV/A, and 404CV/A-EYE come with a check
valve in order to meet ASME A112.3.4/CSA B45.9. This check valve
must be threaded into the discharge port of the 404 cover.
Vent
Provision is made for a vent stack to allow extra volume for high
suds conditions, and to ensure proper drainage of the fixture. The
vent pipe should have a union to facilitate removal, if required,
and shall be connected directly to a building or house vent.
