Drain back theory ,Pump priming

[GaryGary]

Well the taco 009 got it done , just finished the install worked  great  . A little difficult to bleed plus I muted it vertical this time like taco suggested my meter showed it drawing 167 watts  better than 460 that what the sump pump used. Also added 1 inch copper on the u pipe  so far so good the next thing to do is measure flow rate . Just wondering what I should be seeing for tank temps in the winter on good sunny days on average . Thanks again for all the help out there

That's good to hear on the 009. 
Maybe you can let us know how the flow rate comes out.

Can't remember how many sqft of collector you have?

I have 144 sq feet with a flow rate of .03 per sq foot , I need to be around  4.32 . Just guessing I would say it look like 5 gallons a minute more than the sump pump was doing .
