hole and insert the grommet. Slide the 2" PVC drain line into the pipe
grommet, lubricating the pipe if necessary to ease installation.
Note: If installing a washing machine, the preferred method would be to
drain washer into a tub sink with a lint sock prior to the LowPro. Also,
periodically remove access cover and clean lint and debris off of switch
6. NOTE: Threaded connections at tank - HAND TIGHTEN ONLY. Use
Teflon tape as a thread sealant. Install a 2" PVC pipe to the connection
labeled "Discharge". Attach the 2" check valve (Fig. 8, item 14) to the
discharge pipe as close to the top of the tank as possible. Make sure
that the arrows on the check valve are pointing up, away from the pump.
Do not reduce the discharge pipe size below 2".
7. Complete the discharge piping to the house waste line using a minimum
number of turns. See "Note" under Pump Specifications for maximum
head performance of the LowPro system.

10. The rough opening size required for installation using standard 2"X6" floor
joists will vary depending on your actual installation and the orientation of
the tank. The overall rough opening size needed to enclose the entire
LowPro tank is 42" X 24½".
11. Measure the finished flooring thickness and determine the number of closet
flange spacers (Figure 8, item 17) needed to bring the closet flange up to
the finish floor. See Figure 6.
12. Set the proper number of plastic closet flange spacers (as determined in
step 11) onto the brass closet flange. The foam gasket material on the
spacer(s) must be facing down. The spacer(s) will not be secured to the
closet flange, so use care not to move them during the installation of the
toilet.

directions included with the toilet. Install the toilet onto the closet flange
following the directions included with the toilet. Hook up the water line to
the toilet. Turn the water on and fill the toilet tank. Test for leaks. Flush
the toilet several times and allow the pump to cycle to ensure proper
operation.
NOTE: The LowPro features an internal jet spray to help break down solids
and reduce jamming. Due to limited water volumes per pump cycle on
systems of this type, care must be taken to avoid flushing extreme amounts
of toilet paper or any reinforced papers, paper towels, sanitary products and
other foreign objects into the LowPro.
