HELP! Is a 3 Way Valve for Chemical Injection needed?

[Bill P]

Is a 3 way valve needed if your installing Last Step Chemical Injection to a General Pump to bleed the chemical system? So far I have purchased a General Pump Pulse Pump part#100906 and the pulse pump adapter. My machine already has a Dwyer meter. Do I need an additional check valve as well? Suggestions on how to plumb this would be appreciated. Other ideas? Machine is a 2015 EZ3547. Thank you!

Yes. You need a 3 way valve. On/ off and prime.
Prime hose can be ran back to the chemical jug.

This manifold would work

Thank you Justin! Finally getting around to this upgrade!

So when your three way valve is turned to on, it should go to the small opening on the manifold between the check valve and strainer.
Needle valve in between the three way Valve and the check valve strainer so you can adjust flow.

I love this place for this reason alone.


Justin, Charge your phone. 5% is unacceptable.
