Fleck 7000 Sediment Filter Installation & Start-Up
Guide
Thank you for purchasing a Clean Water System! With proper installation and a
little routine maintenance your system will be providing neutral pH water for
many years.
Your new system comes with a printed Fleck Service manual, which along with
this start-up guide will help guide you in the installation and start-up of your new
system. The Fleck service manual covers other types of systems as well such as
water softeners and filters, so there may be information in your Fleck service
manual that does not pertain to your system. Please review this start-up guide
entirely before beginning to install your system and follow the steps outlined for best results.
SEDIMENT MEDIA CONTAINS DUST. USE PAPER MASK AND VENTILATE TO AVOID BREATHING DUST.
IMPORTANT: YOU MAY NOT NEED TO ADD ALL THE FILTER MEDIA YOU RECEIVED. THE FILTER TANK
SHOULD NOT BE FILLED MORE THAN 2/3 FULL.

Pre-Installation
1. Review your packing list and make sure you have received all the parts before beginning installation.
2. If you are going to be turning off the water to the house and you have an electric water heater, shut
off the power to the water heater before beginning installation in case water heater is accidentially
drained.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to freezing
temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation. Installation typically takes 3 to
5 hours. However after installation the Sediment Backwash Filter must be allowed to run through a
complete backwash and rinse cycle.
5. After the system is installed and running, your water may be discolored, or full of sediment or rust,
particularly if this is older or corroded piping. Typically this clears up over a day or two.
Best Practices for Piping & Drain Installation
1. See typical installation (see Fig 2). The Sediment Filter is installed after the pressure tank.
2. Make sure to follow to connect the in pipe to the Fleck 7000 inlet and the outlet to the outlet (see Fig
2). As you face the Fleck 7000 control from the front, the water enters on the right and exits on the
left. From the back (see Fig 2) the water enters on the left. The inlet and outlet are attached to the
bypass valve which is marked with arrows as well.
3. Make sure there is a working gate or ball valve before the Fleck 7000 Sediment Filter and also one
after as shown in the diagram Fig 2. The pressure gauges are optional and perhaps not necessary but
a hose bib (which is a faucet that you can attach a garden hose to) is strongly recommended after the
Sediment Filter before the second ball valve. This makes it easy to rinse your new Sediment Filter on
start-up and gives you a place to test the water before it enters your household plumbing.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the Fleck 7000 control
valve. Avoid heating up the Fleck 7000 control valve plastic with the torch.
5. You do not need unions to install your Fleck 7000 control. If you need to remove it, the Fleck 7000
has quick-release couplings that make it easy to put the Sediment Sediment Filter on by-pass and
remove the filter system from the piping.
6. The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible ½” ID
tubing. Note that the drain can run up above the Fleck 7000 control and into a drain, it does not
have to drain down, as the filter backwashes under line pressure from your well pump. Most
plumbing codes require an air-gap connection, so that if your sewer or septic tank backs up, it cannot
cross connect with the drain tubing.

How Your Sediment Filter Works
See Fig 1. In your Sediment Filter the water enters the top of the tank and flows down through the media and
up the distributor tube. The downflow type Sediment Filter removes sediment and can be backwashed,
which cleans and re-classifies the Sediment, preventing channeling. During backwash, the water flow is
reversed and water flows down the distributor tube and up through the media, lifting and expanding the
Sediment media. During the backwash the Sediment is cleaned by the action of the water flowing through it.

Assembly and Installation Instructions
1. Unscrew by hand the entire Fleck 7000 control valve from top of tank if it was shipped screwed on.
Place distributor tube in tank if not already inside tank. If not already done, make sure blue cap is on
top of distributor tube, or wrap the top of distributor tube with electrical or duct tape. You do not
want Sediment to go down the distributor tube.
2. Note –if you purchased a 3.0 CF system, your system will come with gravel which must be added to
the tank first, before adding the media. If you have a smaller tank proceed with filling the tank with
the Chemsorb filter media. The tank should be 2/3 to 3/4 full.
3. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when
removing cap or tape.
4. If possible at this point, fill tank completely with water. This will allow the Sediment Filter media to
settle and eliminate the need of “purging” the air out of the tank later.
5. Screw on Fleck 7000 control valve carefully. Do not use pipe-joint compound, Teflon tape, or Vaseline
or other petroleum greases to lubricate tank threads.
6. See how the Fleck by-pass is connected (below). Note that Items 2 in Fig 3 below are the pipe
connectors and the other end is what gets attached to the control valve. Items 3 are the red clips
that hold the pipe connectors to the by-pass valve - we include two extra red clips with the pipe
connector kit. Your Fleck 7000 is usually shipped in the by-pass position.

Fleck 7000 Sediment Filter Installation & Startup Guide
Page 9 www.cleanwaterstore.com Rev 051414
Fig 5: Fleck 7000 By-Pass (1) and Pipe Connectors (2)
7. Lubricate the by-pass valve o-rings with some vegetable oil or silicone grease and connect the bypass
assembly to the Fleck 7000 control by sliding the bypass valve firmly into the body of the Fleck 7000.
Once bypass is in far enough, you will be able to insert the red connector clips.
8. Next lubricate the end-connectors (#2 in Fig 3) with some silicone grease or vegetable cooking oil and
insert them into the bypass valve and then insert the red clips (#3).
9. Note that the Fleck 7000 is usually shipped in the bypass position. There is a bypass valve knob on
both the inlet and the outlet (Fig 3 #1). You can easily tell if it is in bypass because the two holes on
the bypass knob will be in the vertical position. If the valve is in the Service position (by which is the
filtering position or ‘in service’ position) the holes will be in the horizontal position. Make sure both
sides are in the by-pass position.

Fleck 7000 Sediment Filter Installation & Startup Guide
Page 10 www.cleanwaterstore.com Rev 051414
10. Do NOT remove the red clips in order to put the bypass valve in either bypass or service, it is not
necessary nor desired to remove the red clips on the bypass valve hand knobs (see Fig 3 item 1, which
are the knobs you will turn to move the bypass valves).
11. Now install your water pipes to the Fleck 7000 bypass end connectors. Make sure inlet is installed to
the 'In" pipe connector on the bypass valve and outlet is on the “Out” connector. Note: Arrows on
bypass valve should be visible from the top of the bypass valve.
12. Connect some flexible tubing from the drain connection on the Fleck 7000 control valve to a suitable
drain such as a septic tank or drain to a sewer. It is OK to run the drain line up and over the Fleck
7000 Sediment Filter up to 4 feet above the top of the tank. If the drain line will be more than 20
feet, use larger diameter tubing such as ¾” or 1”. Note that it is desirable to be able to run the drain
line into a bucket in order to test the backwash flow rate in the future. This is why hard piping the
drain line is discouraged, however, if you do use hard PVC piping for the drain line, and you are able
to remove the hard PVC drain piping and attach flexible tubing should you ever desire for testing
purposes, it is OK to use rigid PVC pipe for the drain. Make sure the drain tubing is firmly clamped to
the barbed fitting with a hose clamp to prevent leaks.
13. For the 2.0 and 2.5 cubic foot systems only: these larger tank systems have an external stainless
steel flow control that comes with the system. This must be installed. If you have a 1.0 or 1.5 cubic
foot system, the flow control is internal and there is no external drain flow control.
Stainless Steel Flow Control (2.0 and 2.5 Cubic Foot Systems Only)
14. Plug in your Fleck 7000 control valve to an outlet. Your Sediment Filter 7000 control valve is already
pre-programmed*. All you need to do is to set the time of day, and then set the number of days the
Sediment Filter will run before it backwashes and regenerates automatically. The default number of
days between back wash is seven.
*If you purchased a metered 7000 valve, please see page twelve for programming instructions.
15. Press and hold either the Up or Down buttons until the programming icon replaces the service icon
and the parameter display reads TD. Set the time of day by pressing the up or down arrows until it is
the current time of day. When the desired time is set, press the Extra Cycle button to resume normal
operation, or wait 5 seconds and the unit will return to normal operation if no button is pressed.

Fleck 7000 Sediment Filter Installation & Startup Guide
Page 11 www.cleanwaterstore.com Rev 051414
16. Hold down the up arrow and down arrow at the same time for 5 seconds. Set the number of days
between backwashes, typically for 1 to 7 days. If your water is very clean (no sediment or iron) you
can set the backwash frequency to as little as every 14 days but its best to leave it to backwash every
1 to 7 days. If there is a lot of sediment in the water, you might want to set to backwash every 1 to 3
days, and if there is moderate sediment and low water use, once a week is fine.
17. Press the Extra Cycle button once. Set the time of the night that you want the Sediment Filter to
backwash. The default time is 2:00 am. Adjust the time by pushing the up or down arrow if you
want.
18. Now press the Extra Cycle button once more. You are done programming!
19. Now you are ready to turn on the water. Turn on the water and leave the Sediment Filter on bypass
and check for leaks. Leave the ball valve after the Sediment Filter closed, so water is still off to the
house, but connect a garden hose and open up the hose bib after the Sediment Filter and allow the
water to run for several minutes. This important step clears out any foreign material that may be in
the pipes from the piping installation. If you do not have a valve installed after the Sediment Filter
and you do not have a hose bib, you will need to turn the water on inside the house to let the water
run. Use a bathtub or laundry sink or other fixture that does not have an aerator screen.
20. Press the Extra Cycle button for a second or two which will start a manual backwash.
21. Now you can slowly turn the bypass valve to the service position. You do NOT remove the red clips
on the bypass knobs in order to turn the bypass valves from the bypass to the service position. First
open the Inlet Side of the bypass valve. Second slowly open the Outlet Side of the bypass until it is in
the full service position. The Fleck 7000 bypass valve knobs are a little stiff, so you can use a screw
driver placed in the holes to turn the knobs. Make sure you are turning the bypass valve knobs in the
correct direction which is counterclockwise as you face the bypass valve knobs.
22. There should be no Sediment media coming out of the drain line, but the water will be gray or dirty
looking. At this point the Sediment Filter will be in a backwash cycle. The backwash takes 10
minutes. If the water slows down or stops during the first 10 minutes of backwash, press the Extra
Cycle to move the Fleck 7000 control to the next cycle, the Rinse cycle. Then repeat the backwash
and rinse after the rinse cycle is done, by pressing the Extra Cycle again. If you have high water
pressure you may need to turn on the water slowly to the Sediment Filter at first to prevent some
Sediment fines from coming out the backwash. However it is normal for some small amount of fines
to come out during the backwash, although you do not want to see a large amount of media coming
out, which would mean you have very high water pressure, or the drain flow for the Fleck 7000 is
missing.
23. If possible verify that the backwash flow is 7 gallons per minute, which is the recommended backwash
flow rate for 1.0 and 1.5 cubic foot models. The 2.0 cubic foot models require 10 GPM an if you have
a 2.5 cubic foot Sediment Filter it should be backwashing at 12 gallons per minute. You can easily run
the drain hose to a bucket and using a watch verify the flow rate in gallons per minute. An adequate
backwash is critical to properly clean the Sediment media and prevent it from cementing together.

Fleck 7000 Sediment Filter Installation & Startup Guide
Page 12 www.cleanwaterstore.com Rev 051414
24. The next cycle is the Rinse cycle and this also runs for 10 minutes.
25. After the Sediment Filter has gone through the backwash and rinse, press the Extra Cycle button and
repeat the backwash and rinse. This is the same procedure that needs to be done each time you add
Sediment media in the future, that is, the Sediment media must be thoroughly backwashed and
rinsed.
26. Refer to your Fleck 7000 service manual for more information about how your control valve is
programmed if desired.
Fleck 7000 Metered Flow Sensor Filter System Programming Guide
This is for Fleck 7000 backwash filters that have are equipped with the optional built-in flow sensor only. There are
two types of programming, standard USER PROGRAMMING, where you can set the time of day and gallons of
water used and/or days between backwashes. The second type is MASTER PROGRAMMING where you can
set the length of the backwash and rinse cycles, and make sure the control is set to the correct settings for
your type of Sediment filter:
User Programming
You can go into User Programming and make adjustments if you want to the flow meter setting or Day
Override setting. Use the User Programming to avoid having to go through the Master Programming for quick
changes to these settings below:
1. Press the Up and Down buttons for five seconds while in service, and the time of day is NOT set to
12:01 PM.
2. Day Override (Display Code DO): Set to 1 to 14 based on your particular filter system requirements.
Use the Up or Down arrows to change the setting. This is the critical setting that allows your filter to
backwash every fixed number of days. See your Installation and Start-up Guide for more information
or contact us for suggestions for this setting. Press the Extra Cycle button.
3. Regeneration Time (Display Code RT): Set to 2:00 am generally or sometime when no water is being
used, and no other filter or softener is likely to be in a regeneration cycle. Press the Extra Cycle
button.
4. Feed Water Hardness: Use this setting to adjust the feed water hardness. Set for 20 for most
applications. Press the Extra Cycle button. Note that actual ‘Feed Water Hardness” is irrelevant to
filter systems, since no hardness is being removed.

Fleck 7000 Sediment Filter Installation & Startup Guide
Page 13 www.cleanwaterstore.com Rev 051414
5. Press the Extra Cycle button to end User Programming Mode
Master Programming Mode (for Flow Sensor type)
Perform a Master Reset: Unplug the Fleck 7000 from the electrical wall outlet. Hold the Extra Cycle button
while plugging in and powering up the unit. This resets all of the parameters in the unit.
Enter Master Programming Mode: Set the Time of Day display to 12:01 P.M. Press the Extra Cycle button (to
exit Setting Time of Day mode). Then press and hold the Up and Down buttons together until the
programming icon replaces the service icon and the Display Format screen appears.
Note, that when the Master Programming Mode is entered, all available option setting displays may be
viewed and set as needed. Depending on current option settings, some parameters cannot be viewed.
1. Display Format (Display Code DF): Set display to GAL (stands for U.S. Gallons), or change to Liters or
Cubic Meters if out of the U.S. Press the Extra Cycle button to go to the next step.
2. Valve Type (Display code VT): Set to DF2b. This means it is set for standard Down-flow mode,
similar to a water softener so we can take advantage of the flow meter in this Fleck 7000 5-cycle
valve, but we won’t be using all the 5 cycles that the water softeners use. Press the Extra Cycle
button to go to the next step.
3. Control Type (Display Code CT): Set to Fd. This is the Meter Delayed option. This tells the Fleck
7000 control to meter or keep track of the amount of water used, but then wait until the pre-set
regeneration (backwash and rinse cycles) time, typically in the middle of the night. Press the Extra
Cycle button.
4. Unit Capacity (Display Code C): Set to 30. Use this display to set the Unit Capacity. This setting
specifies the treatment capacity of the unit. Since we are not using this for softening, where the
capacity of the softening resin can be accurately defined, 30 is a number we can start with. This can
be set higher or lower later which will allow the meter to backwash more or less frequently based on
the capacity. Press the Extra Cycle button.

Fleck 7000 Sediment Filter Installation & Startup Guide
Page 14 www.cleanwaterstore.com Rev 051414
5. Feed water Hardness (Display Code H): Set to 10 to 20. This is the feed water hardness that allows
the meter to calculate the number of gallons between backwashes. It is a little meaningless for filter
valves, and is designed for water softeners which remove calcium hardness in grains per gallons.
However, if you set it to 20, to start with, you will later see the number of gallons between cycles
when you are finished programming based on your size of system. It is not that critical, because you
want the filter to backwash once a week or every few days based on the type of filter system you
have, by setting the Day Over-Ride.
6. Reserve Selection (Display Code RS): Set to SF. It is not relevant to filter control valves.
7. Safety Factory (Display Code SF): Set to 0.
8. Day Override (Display Code DO): Set to 1 to 14 based on your particular filter system requirements.
Use the Up or Down arrows to change the setting. This is the critical setting that allows your filter to
backwash every fixed number of days. See your Installation and Start-up Guide for more information
or contact us for suggestions for this setting. Press the Extra Cycle button.
9. Regeneration Time: (Display Code RT): Set to 2:00 am generally or sometime when no water is being
used, and no other filter or softener is likely to be in a regeneration cycle. Press the Extra Cycle
button.
10. Regeneration Cycle Step Times: Use this display to set the various minutes of each cycle. Some of the
cycles will be set to 0. Do not set any of the cycles to Off. Use the Up or Down arrows to change the
setting to the desired setting. Press the Extra Cycle button to accept the setting and move to the next
parameter.
a. B1 –Backwash: Set to 8 to 10 minutes.
b. BD - Brine Draw: Set to 0.
c. B2 - 2nd Backwash: Set to 0 for most applications.
d. RR -Rapid Rinse: Set to 6 to 8 minutes
e. BF - Brine Fill: Set to 0.
f. SV - Service (meaning it is in Service or filtering mode) no setting is needed for this. Press
the Extra Cycle button

Fleck 7000 Sediment Filter Installation & Startup Guide
Page 15 www.cleanwaterstore.com Rev 051414
11. Flow Meter Type (Display Code FM): Set to t1.2 (this is standard Fleck 7000 meter). Press the Extra
Cycle button.
12. Press the Extra Cycle button to save all settings and exit Master Programming Mode. Note that the
control valve may take several minutes to re-home and re-set after the Master Programming steps,
do not unplug the control during this process.
Troubleshooting the Fleck 7000 Sediment Filter
Low Water Pressure:
Make sure it is backwashing frequently enough, in some cases every 1 to 2 days is necessary.
Check backwash flow rate: One problem that may occur is if you do not have enough backwash flow rate to
properly clean the Sediment Filter. You can verify the backwash flow rate by running the drain line into a
bucket and timing it when the Fleck 7000 is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should
have 7 gallons per minute and a 2.5 cubic foot system should have 10 gallons per minute of backwash at a
minimum.
Check programming: In some cases, the Fleck 7000 may not be programmed correctly. See the Fleck 7000
service manual for instructions on how to access the master programming.
Does NOT remove sediment:
Make sure it is not on bypass, see bypass valve positions (page 6)
Fleck 1.03” adapter when using a Vortech tank is missing. Remove control valve and make sure o-ring on
Fleck 7000 valve that seals around distributor tube is present, and is sealing tightly around distributor tube.
In some cases the sediment may be too small to be removed by the filter. One way to determine that the
filter system is working is to run it for one or two weeks until the pressure drops after the filter. Then
manually backwash and observe the backwash water. If the filter has been removing sediment, the backwash
water will be quite dirty and full of sediment. If the backwash is clean, then the particles are less than 5 to 10
microns, and an alum injection system is required to clump the particles together into a larger 5 to 10 micron
form.

What to Do If Your Filter Tank Does Not Sit Level on the Floor
Your black filter tank base is not glued to the bottom of your tank. Occasionally tank bases will become
crooked during shipment. If you find that that your tank does not sit level on the floor, you can easily adjust it
by holding the empty tank and rapping it on a concrete or solid floor once or twice in order to level it.
How to Remove the Red Clips from Fleck 7000 Control Valves without Breaking
Them
The Fleck 7000 is a great programmable control valve that lasts many years. While it is easy to install and
program, reading this guide prior to installation can save you some time when removing the red clips.
What happens is, when the water is first turned on and the control valve comes up to line pressure, the
bypass valve and pipe connectors push out or push apart slightly and lock in the red clips. When the water is
turned off, and even if there is no water pressure, it’s impossible to remove the jammed in clips, without
great difficulty, and eventually most customers end up breaking them to get them out.
Step 1: Turn off water to the Fleck 7000 and relieve the water pressure by opening up a faucet in the house.
You can also put the Fleck 7000 on bypass, by turning the bypass valves to bypass. Either way, the 7000
control valve must be depressurized before removing the red clips.
Step 2: At that point they can practically be removed with your fingertips, although a small flat head screw
driver or needle nose pliers works best to pull out the red clips.
