Find a suitable location on the tank floor for the drain to be installed, taking into consideration the
placement of the unit on a trailer. LOOK under the deck for obstructions (cross-members, wiring, and axles,
ect.) Allow room for a shut off valve.

Drill holes into floor of tank using the top (inside) portion of the drain as the template.

Make sure the holes are free of burs and both surfaces are clean.

Install the drain bung as per FIG 1. Note the gaskets are on the inside and outside of the tank.

Tighten nuts as to slightly squeeze the rubber gaskets.

Cut a hole into the deck of the trailer or truck for the piping and valve to be installed.

Install 2” pipe nipple and valve into tank bung with a sealant on the threads. CAUTION: DO NOT OVER-
TIGHTEN!

The nipple and valve should not extend to far from the tank without a support, as this will cause excess
stress on the threads, drain bung and the tank floor.

Fill with water and check for leaks.
