Installation Requirements
PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included), measure and
cut to the length needed.
=
Avoid drain hose runs longer than 10 feet. Make
the valve drain line as short and direct as possible.
=
If possible, avoid elevating the drain hose. This
could reduce the effectiveness of the flush cycle,
especially in a low pressure application.
=
The drain must be capable of handling a flow of 5
to 10 gallons per minute, depending on the home’s
water pressure.
=
The drain must be capable of handling the sediment
being flushed from the filter.

FLOOR DRAIN
In the state of Massachusetts: The Commonwealth
of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used
for this installation.
AIR GAP REQUIREMENTS
A drain is needed for sediment flush discharge water.
A floor drain, close to the Automatic Sediment Filter, is
preferred. A laundry tub, standpipe, etc. are other
drain options. The valve drain hose must be secured
in place, since drain water will be spraying from the
end of the hose at a high rate during flush cycles.
Leave an air gap of 1-1/2” between the end of the
hose and the drain. This gap is needed to prevent
backflow of sewer water into the Automatic Sediment
Filter. Do not put the end of the drain hose into the
drain.

GROUNDING INFORMATION
(for Installations on Metal Pipe)
The house main incoming water pipe is often
used to ground electrical outlets in the home.
Grounding protects you from electrical shock.
Installing the Automatic Sediment Filter may break
this ground. To restore it, buy and install a #4
copper wire across the filter, tightly clamped at
both ends, as shown below.
IMPORTANT:
Flow rate to drain can
exceed 9 gpm at high-
er pressure. Be sure
to secure drain hose
properly and test.
