PROJECTS: Mobile Handwash Station
½" drill bit or hole saw to cut the hole.
1b. Separate the two pieces of a ½" bulkhead
union washer fitting (Figure
A
), leaving one
washer per piece. Push the piece with the
threading through the hole you have cut and screw
the other side on, on the underside of the lid.
1c. Wrap a few layers of PTFE tape (Figure
B
)
around the threaded areas of two ½"×¾" PVC male
reducer adapters (Figure
C
).
1d. Screw the PVC reducers into the top and
bottom sides of the bulkhead fitting.
1e. Cut a 3" length of ¾" PVC pipe (Figure
D
) and
slide it into the PVC reducer that’s on top of the lid.
1f. Slide a ¾" PVC elbow (slip × FPT) (Figure
E
)
onto the 3" pipe.
1g. Wrap a few layers of PTFE tape around the
threaded areas of a ½" brass barb × ¾" MPT
reducing adapter (Figure
F
) and screw it into the
FPT side of the elbow. Place the lid to the side.
1h. Measure the distance from the top of the bin to
½" above the bottom of the bin. Cut a ¾" PVC pipe
to this length. Cut the bottom end of this intake
pipe at an angle. You want it to stop ½" before
hitting the bottom of the bin, to prevent sediment
from being picked up by the pipe when pulling
fresh water.
1i. Slide the non-angled end of the PVC pipe into
the PVC reducer on the underside of the lid, then
place the lid back on the bin.
TIP: To make sure the ¾" PVC pipe isn’t hitting the
bottom of the bin, press on the lid and try to feel if the
pipe is hitting bottom. You can also try lifting the lid on
one side and peeking in. If it’s too long, simply cut it
shorter with the PVC cutter.
2. DISHPAN CUTOUT AND FAUCET
2a. We recommend placing the 12qt dishpan
(Figure
G
) centered on the lid, but slightly forward,
closer to where the guest will be washing their
hands. This gives ample room for the dishpan and
faucet. With a marker, trace the circumference
of the sink basin on the top of the lid; you will be
cutting along this line.Place the dishpan aside.
2b. Use a handsaw or a Dremel equipped with a
plastic cutting wheel to cut along the traced line
on the lid. You may need to trim the hole slightly a
few times in order to get it just right. The dishpan
will not be glued in, so the goal is to get it to sit
comfortably and securely in the lid while allowing
easy removal for access to eliminate the greywater
that will fill this bin.
2c. Place the faucet to the rear of the dishpan.
There should be just enough room; approximately
½" between the dishpan and the faucet (another
½" bulkhead fitting). Use the drill with a ½" hole
saw to cut the hole for your faucet (Figure
H
).
2d. Install the bulkhead fitting into the ½" hole
you drilled.
2e. Wrap a few layers of PTFE tape around all
threaded parts of two more ½"×¾" PVC male
reducers, then screw one into the top and one into
the bottom of the bulkhead fitting.
2f. Cut a length of ¾" PVC pipe at the desired
height for your faucet.
2g. Slide this pipe into the PVC reducer on top of
the lid.
2h. Slide a ¾" 90° PVC elbow (slip × slip) (Figure
I
) onto the pipe.
2i. From the curved portion of elbow, measure
