Doser hook up Question? Re: check valves

[lastlight]

No check valves and my SA3 is working perfectly.

Sweet, less work is better. That's why I bought the SA in the 1st place. No more over-thinking, just calibrating. Thanks guys.

I pump 6 or 7 feet up. My pumps put out 47mL/min since you didn't ask =)

The GHL doser motors all come with 3 rollers which will actually help to prevent back flow, so ya, no worries there.

However, not all dosers are created equal. There are a lot dosers with just two rollers and with only two rollers there is definitely the potential of back flow.
