PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
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 Clean Rinse discharge water. A
floor drain, close to the Central Water Filtration System,
is preferred. A laundry tub, standpipe, etc. are other
drain options. Secure valve drain hose in place. 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 Central Water Whole Home
Filtration System. Do not put the end of the drain hose
into the drain.
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included), measure and
cut to the length needed. Flexible drain hose is not
allowed in all localities (check your plumbing codes). If
local codes do not allow use of a flexible drain hose, a
rigid valve drain run must be used. Purchase a com-
pression fitting (1/4 NPT x 1/2 in. minimum tube) and
1/2" tubing from your local hardware store. Plumb a
rigid drain as needed (see Figure 3, below).
NOTE: Avoid drain hose runs longer than 30 feet. Make
the valve drain line as short and direct as possible.
It is recommended that the Central Water Whole
Home Filtration System be installed near a drain.
However, if a drain is not available, it is still possible to
operate the Central Water Whole Home Filtration
System in a manual Clean Rinse mode. See "Operating
in Manual Clean Rinse Mode" section. The automatic
Clean Rinse function must be disabled if the Central
Water Filtration System will not be connected to a drain.
