Typical Installation Diagram
How To Set Up Your Alum Pump To Turn On and Off Automatically

J-PRO-22 Alum Guide Rev 0021622 Page | 5
The pump is designed to pull Alum solution out of a solution tank and pump a precise amount of Alum
into a pipeline under pressure.
Right out of the box, this is a dual-voltage (110/220) pump.
There are several ways to wire the pump such that it triggers
when there is water flow.
The well pump is controlled by your pressure switch.
Choosing one of the ways outlined below, the J-Pro-22 pump
will be installed so that it powers up and injects Alum when the
well pump and motor are turned on via the pressure switch.
1. You can wire it to your well pressure switch, using a
dedicated electrical wall outlet.
2. You can install a flow switch and plug the J-Pro22 into that.
3. You can cut the plug and wire direct to pressure switch. Note that the
ground wire is yellow color, brown and blue are hot wires.
Wire To Pressure Switch Option

J-PRO-22 Alum Guide Rev 0021622 Page | 6
You may cut off the 110-style plug and wire a 220-style plug, and then plug that into a
dedicated 220- style wall outlet.
Install a dedicated wall outlet that is wired to the pressure switch and powered up
whenever the well pump turns on.
The J-Pro-22 is a dual voltage pump. It has a 110 volt- style plug but can run on 220v or
110v. It uses a maximum of 22 watts power when running.
Use Pre-Wired Flow Switch Option

J-PRO-22 Alum Guide Rev 0021622 Page | 7
As an option to turn on and off the Alum pump, install a flow switch. No electrical wiring to do and any
plumber, or person familiar with basic plumbing, can install it.
Simply plumb the pre-wired flow switch into your service pipe. Plug the flow switch into a standard 120V
wall outlet.
Then, plug the Alum pump into the electrical outlet on the flow switch. Whenever there is flow, the
metering pump will then turn on.
J-PRO-22 Installation
Instructions
While you can mount the pump on a shelf
above the solution tank, it is strongly
advised to mount the pump directly on top

J-PRO-22 Alum Guide Rev 0021622 Page | 8
of the solution tank. If the tubing from the foot valve to the suction side of the pump exceeds 60”, the
unit will not have enough lift force to stay primed.
Mount Pump to Solution tank
Place pump on tank. Mark where the anchor holes will
be drilled. Drill pilot holes with a small drill bit so that
the pump can be mounted on the tank with two wood
or sheet metal screws. We recommend screwing them
in after the pump has been primed and the tubing has
been hooked up for easiest installation.
Mark the holes for the suction tube and the degassing
valve return line and drill holes.
How to Connect Tubing & Fittings
•Trim the end of the tubing square (cut with a new box cutter blade).
•Slide the connector nut onto the
tube.
•Push the tubing over the conical
fitting until the tubing is flush against
the end of the fitting.
•Screw the connector nut on, hand
tight.
•Do not use Teflon tape/ paste on the
tubing fitting connections.
Use the harder/stiffer translucent tubing for connection from discharge-side (12 o’clock) to
the injection check valve.
Use the softer clear tubing for the foot valve to suction-side (6 o’clock) connection.

J-PRO-22 Alum Guide Rev 0021622 Page | 9
Install Discharge Side Tubing
This is the tubing that goes from the pump
discharge (outlet) to injection check valve in
pipe tee.
1. Shut off well pump or water supply and
de-pressurize service pipe.
2. Install injection check valve by installing
a pipe tee in your pipe that has a ½”
NPT fitting, where you can screw in the
injection check valve (included with
your J-PRO-22 pump).
3. Wrap Teflon tape on the ½” pipe
threads of the injection check valve
and apply a light coating of white
Teflon pipe paste and install into Tee
fitting.
4. Trim the end of the injection check
valve fitting so that the end (where the
Alum squirts out) will be in the center
of the service pipe.
5. Make sure to install injection check
valve in to pipe directly. If the end of
the check valve is not in the service
pipe, it will not work. Do not install a
ball valve, or any length of pipe run, coming off the tee.
6. Using a hack saw or cutter, trim the end of the injection check valve if needed, so it inserts into
the water pipe as shown.
7. Install tubing that came with your pump and connect pump to injection check valve.
8. Cut tubing to desired length with enough slack to avoid kinks.
Injection check valve can be installed into PVC, copper or other piping.

Install Suction Tubing from Pump to Solution Tank
Connect hard tubing from foot valve in Solution Tank to Inlet/ Suction side of metering pump
1. Measure the tubing from the outside of the solution tank to ensure it will be 2-3” from the
bottom of the solution tank.
2. Do not allow weight to sit at the bottom of the tank. Connect tubing to the foot valve and put
the ceramic weight on.
3. Run the tubing up through the hole and connect to the Inlet/ Suction side of pump

Connect Tubing from Degassing Port (“Kicker Port”)
You can use the soft tubing for this run, connect tubing to the degassing port fitting, pass tubing through
the hole you drilled down into the tank 4-6”.

J-PRO-22 Alum Guide Rev 0021622 Page | 12
Prime & Start the Pump
1. Fill solution tank with 5 gallons of softened, distilled or RO water but don’t add Alum yet.
2. Connect the suction tubing to the foot valve and discharge tubing to your injection check valve.
3. Connect the degassing prime valve tubing and route to the solution tank, above the water line.
4. Open the degassing prime valve approximately one turn counterclockwise to open. This will
allow the solution to be pumped back into the tank for fast priming.
5. Turn on the pump and set Speed to 100% to help prime the pump if not already displaying 100
6. You will quickly see water being pumped up the suction tubing and out of the degassing valve
return line port.
7. Close the degassing port valve to allow liquid to pump out the discharge side. Open and close
degassing valve as required to prime pump. Close degassing valve once pump is primed for
normal operation.
8. To start mix 2 lbs of alum powder (2-1/2 Cups) in to the 5 gallons of water and mix thoroughly.
Some alum may not mix and settle which is normal.
9. Turn on system or run water and allow to run for 10-15 minutes. Check for leaks. After your
Alum metering pump has been running for a few days, tighten 4 stainless steel bolts on the
pump end.
Metering Pump Buttons
Out of the box, when you plug the unit in, the green Motor light is
indicating the pump has power. It will be set at 100 and start pumping.
Press the Start/Stop button to stop the unit from pumping. The Up and
Down arrows are to adjust the Speed of the pump, from 0-100.
The Set button and the Auto light indicator have no function on this
model, they are for use with a flow meter.

J-PRO-22 Alum Guide Rev 0021622 Page | 13
Solution Strength and Settings for Alum
Alum injection can be used to treat cloudy water. Alum is considered by the FDA as a generally
recognized as safe (GRAS) substance. It is an inorganic salt, also called potassium aluminum sulfate.
A typical system for small well water systems can be set up by injecting the alum prior to the well
pressure tank and allowing the water to flow through to a contact retention tank to allow the alum to
mix and treat the water.
The amount and dosage of Alum varies widely based on water chemistry and we cannot make a firm
recommendation as it must be tried out on site with your particular water.
To start with we recommend injection of alum at 3 to 10 PPM then running through a contact tank as
large as you can get, for example 120 gallons is good.
After alum contact tank filter the water with a sediment backwash filter, with 25/1 micron big blue filter
cartridge and then optionally a Nano-Ceram micro filter to take out very fine particles.
To make up a 2.5% solution (25,000 PPM) mix 1 lbs (which is same as 1-1/4 cups) of alum powder for
every 5 gallons of water, which is approximately a 2.5% solution by weight.
It is best to use warm purified distilled or reverse osmosis water to make up your solution.
You can get some alum and do jar testing as well, which is what water treatment plant operators do.
In municipal water treatment it is OK to inject up to 50 PPM, but it does contain aluminum so it’s
important not to inject more than 50 PPM. 3 to 10 PPM is standard. More alum is not better, generally
you want to inject enough to get the flocculation started in the contact tank. Flocculation is where the
suspended particles clump together to form larger particles that can be filtered.
Each water chemistry is different and alum injection does take some adjustment to achieve the best
results. We recommend starting out with a 5 PPM applied dosage.
After injection, a Sediment / Turbidity Backwash Filter is recommended.
As a final stage, a Nano-Ceram filter system is recommended. This removes fine particles and turbidity
as well as filter coliform bacteria if present.

J-PRO-22 Alum Guide Rev 0021622 Page | 14
Formula for Calculating Solution Strength and Settings
How Should I Prepare My Alum Solution?
Note that “mg/L” is the same as “Parts Per Million”, or PPM.
If you added 1 lbs (1-1/4 cups) of Alum to 5 gallons of purified or distilled water, you would end up with
approximately 25,000 PPM solution.This is the solution strength you can start out with in this formula
example below.
The simple formula is:
Flow Rate in Gallons Per Minute (“GPM”) x Parts Per Million of Applied Dosage (“PPM”) x 1440 Minutes
in One Day = Gallons of Alum Used Per 24 Hour Period.
This means, that if your well pump or the pipe that you are injecting the Alum into, runs for 24 hours,
you would use that number of gallons.
Example:
Assume you wanted to inject 10.0 PPM of Alum into your well water. You added 2 lb of Alum with 5
gallons of distilled water, which is approximately a 50,000 PPM Alum solution strength. You know your
well pump flow rate is 12 GPM.
10.0 PPM x 12 GPM x 1440 Divided by 25,000 = 7 Gallons Per Day
What this mean is approximately 7 gallons of the Alum solution will be pumped for every 24 hours your
well pump runs.Your well pump does not run 24 hours each day usually.
For example, If your well runs 2 hours a day, in 12 days you would use about 7 gallons of the diluted
Alum solution.
In our example here, you need an Alum pump that can pump 7 gallons in 24 hours. The JPRO-22 pump
pumps 22 gallons per 24 hours. So: 7 divided by 22 = 30%
Therefore, in this scenario set the JPRO-22 to at 30% speed.If your well flow rate is much lower than
12 gallons per minute, you can use a more diluted alum solution. If your flow rate is higher you can turn
up the speed of the pump.

Troubleshooting and Maintenance:
Most problems occur with the connections, it can sometimes be hard to push the tubing onto
the cones, sometimes fittings are over-tightened, or people use Teflon tape and paste on
fittings that do not need it.
If the pump pumps in manual mode and makes a thumping sound, then it is working.

Priming Problems
1. If you cannot get it to prime, it is either because a fitting is too loose, too tight, or not
installed correctly.
2. While the pump is running (usually, on Manual), observe if the fluid is coming up the
tube- if you see the water going up and down in the tubing, this indicates the foot valve
is not tight, or you installed the pump too high above the solution tank, or you mounted
the pump improperly.
3. Sometimes, as mentioned earlier in the guide, it is because the four Allen head bolts on
the grey pump head have loosened, and need to be tightened, do not over-tighten.
4. If the solution has filled the tubing, but it is not discharging, make sure the de-gas is
opened, and then close it until the point when it starts pumping.
5. The tubing going from the outlet/discharge to injection check valve will twitch and
move at the same time the pump triggers, that is how you can confirm you are
pumping solution.
6. If this does not work, remove the discharge-to-injection check valve tubing from the
outlet fitting, and see if it squirts out of the top- if it does, this indicates that the
problem is in the injection check valve, or that you are trying to pump against greater
than 100 psi.

J-PRO-22 Alum Guide Rev 0021622 Page | 16
Maintenance Tips:Check Alum residual at least once per month and adjust the J-PRO-
22Pump and/or solution strength if needed.
Winterizing: do not let the J-PRO-22Pump or tubing freeze. If you need to winterize, drain the
solution tank and discard Alum solution.
Place the suction of the pump into a bucket of clean water and allow the pump to run until the J-
PRO-22Pump is free of any Alum solution.
Remove the suction from the water and allow the pump to pump dry. Pump is ready to store.
NOTE: if diluting Alum, use only distilled water, water from a reverse osmosis system, or at
least softened water. Do not use untreated well water.
