    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!

    02A871F2-32C7-46A6-906C-89F5DAA786FD.png Yes. You need a 3 way valve. On/ off and prime.
    Prime hose can be ran back to the chemical jug. 88BBC6B0-8B53-4DF4-8085-7F319F8B2092.png

    Needle valve in between the three way Valve and the check valve strainer so you can adjust flow.
