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.
