WH1-HF
High Flow Series Whole
House 10 Micron Sediment
Filter Package
Package Contents:
• one (1) heavy-duty Pentek Big Blue 20” filter housing (1” NPT) w/ pressure relief button
• one (1) mounting bracket and related screws
• one (1) Hydronix SDC-45-2010 multi-gradient sediment filter cartridge
• one (1) spanner wrench
This high capacity whole house filter package is designed specifically to remove sediments down
to a level of 10 microns thereby improving water clarity, taste, and odor, and protecting your
home’s plumbing system (including other water treatment equipment) from damage and premature clogging due to sediment build-up. This package features Hydronix's unique SDC Series
multi-gradient sediment filter. This filter uses the entire depth of its media by trapping the largest
sediment particles on the outside of the filter, then gradually stepping down the size of particles it
will reject as the water moves closer to the core of the filter. The outer layer is rated at 75
microns. The subsequent layers are rated at 50 microns, 25 microns, and finally 10 microns. The
result is longer filter life, greater dirt-holding capacity, higher flow rates, and remarkably low
pressure drop. The 100% pure polypropylene media is highly resistant to bacteria, making this an
excellent choice for both well water and municipal water treatment applications.

Note: We recommend that this product be installed by a professional plumber. If you
install this product yourself, please ensure that your installation meets all local building
and plumbing codes. The following instructions are meant only as a general guide and
should not be considered a substitution for your local plumbing and / or building codes.
Typical Installation:
You will need the following plumbing supplies:
• two (2) shut-off valves with suitable sized unions to connect to your incoming and outgoing
water lines. You can select threaded, compression or sweat (soldered) fittings on the shut-
The plumbing connections on the inlet and outlet of the water filter housing are 1” inside diameter
(female) NPT threaded fittings. You may require additional plumbing adapters to connect to your
selected shut-off valve. Your plumber will have all of these items, or they can be purchased at
your local hardware or plumbing supply store at minimal cost (take these instructions to the store
with you so the store clerk can make sure you get everything you need). Note: In older homes
with galvanized piping all fittings should be threaded.
STEP 1. Select an installation location. There are a variety of ways to install your filter system
into a main or branch water line. As a general recommendation, this filter should be installed on
the main cold water line after the pressure tank or water meter. Select an installation location
with convenient access for regular filter replacements and maintenance.
STEP 2. Shut off the main water supply and drain the pipes. Opening the highest and lowest
fixtures in the house will help drain the pipes.
STEP 3. Using a pipe cutter, cut out a section of your main water line at the point where you
want to install your filter system. There will probably be some water remaining in the system, so
be sure to have a bucket and some rags handy to clean up any small spills. Make sure that the
section of water line you remove is appropriately sized such that all of the components of the
system including the shut-off-valves, adapters, and the black filter cap will fit snuggly when
assembled. If in doubt, cut a smaller section at first – you can always remove a slightly larger
section upon final assembly if necessary.
STEP 4. Assemble the components according to Diagram 1 below. We recommend installing
shut-off valves both upstream and downstream of the filter housing. A shut-off valve is not
required on the upstream side of the housing if the filter will be located within a couple of feet of
the main line shut-off valve. Plumber’s cement or Teflon tape should be used on all threaded
fittings. Use the mounting bracket and screws provided so secure the black filter housing cap to
the wall or other solid surface. Allow enough space below the black cap to accommodate the blue
housing sump plus a minimum of an additional 3 inches of clearance.
Use extreme caution when soldering any connections between the main water line and
the shut-off valve or between the shut-off valves and filter housing if your filter housing
electrical systems, appliances, or your phone line. If this is the case, be sure to install
regulation ground clamps to the metal pipe on each side of the plastic filter housing and
off valves as desired.
• plumber’s cement or Teflon tape for all threaded fittings.
IMPORTANT WARNINGS:
is connected to the pipes, or serious damage to the filter housing could occur. If at all
possible, solder all connections before the pipe is connected to the filter housing.
If your water pipes are metal (galvanized or copper), they may be used to ground
connect a jumper wire between the 2 clamps (#4 gauge solid copper wire
recommended). Alternatively, your plumbing code MAY allow you to connect the
jumper wire to the 2 shut-off valves (see diagram). Consult a certified electrician or
plumber if you are unsure.
