OPW Installation and Maintenance Instructions
OPW 1DK-2100 EVR Replacement Drain Valve
IMPORTANT:
Please read these warnings and use
the assembly instructions completely and carefully
before starting. Failure to do so may cause product
failure, or result in environmental contamination due
to liquid leakage into the soil, creating hazardous
spill conditions.
IMPORTANT:
Check to make sure the unit is
intact and undamaged and all parts have been
supplied. Never substitute parts for those supplied.
Doing so may cause product failure and void
warranty.
WARNING-DANGER:
Using electrically operated
equipment near gasoline or gasoline vapors may
result in a fire or explosion, causing personal injury
and property damage. Be sure that the working area
is free from such hazards, and always use proper
precautions.
NOTE:
At all times when product is in the storage
tank keep the riser pipe capped, so the vapors
cannot escape into the environment.
The OPW 1DK is an optional drain valve
replacement kit for the OPW 1 Spill Container
Series. It is designed to return incidental spillage
of liquid back to the underground storage tank.
HOW TO INSTALL
1. Remove and discard existing drain valve and O-
ring.
2. Clean any dirt or debris from the sealing surface
where the new drain valve will be installed.
3. Apply any common grease or light oil to the new
supplied O-ring. Assemble the O-ring into the
spill container base.
4. Insert the 1DK into the spill container O-ring. Be
sure that the drain valve seats flush with the
floor of the spill container base.
5. The pull lever of the 1DK MUST be positioned
halfway between the riser pipe nipple and the
spill container bellows. Rotate the drain valve
until that position is attained.
6.
Secure the 1DK by installing the provided
retaining clips and nuts. Tighten the nuts to a
torque of
11.5 ft-‐lbs min. to 13.5 ft-‐lbs max.
7. The drain valve is now installed and ready for
testing.
HOW TO TEST
Upon preliminary installation perform the California
Test Procedures TP-201.1C or equivalent. These
Test Procedures will check the seals between the
drain valve, nipple and rotatable adaptor. To test the
spill containers base and bellows fill the container
with water. A drop in the water level of 1/16” or
more after one hour means that a leak exists. To
determine where the leak is, look for a steady
stream of bubbles coming from one of the joints.
NOTE:
Do not drain the water into the UST after the
test is complete. Water must be disposed of per
local requirements for hazardous waste.
If a leak is observed in the Test Procedure, check to
see that the drain-valve poppet is sealing properly.
To do this, lift up the drain-valve pull chain several
times to actuate the poppet. This will ensure that
the drain-valve poppet is seating properly. If this
doesn’t correct the leak remove the 1DK valve and
inspect the O-ring for nicks or tears, replace if
needed; also clean the sealing surfaces of the spill-
container base that the 1DK valve and O-ring are
installed into. Reinstall 1DK valve and repeat test.
If spill container passes the Test Procedure but does
not hold water then there is a leak in the bucket and
it will need to be replaced.
