Thanks for all the answers--and the pics (bigben2k) .
I like the option 2 on the drawings better than option 1
It just seems to me that pump to pump, that you would limit your flow to the lowest rate one,although with a lot more head capablities (sp.) I hope that spelling cop ain't here
I think I ask for reduancy and yall gave me the answers. But what I really wanted was reduancy with no flow loss. I don't think I can get both. (my fault). Right now getting 120 GPH with the AV1300 and don't want to go down. When I check it with the 1048 running it only barely improves (29--27 sec. to fill gal jug). a big problem is I don't want to change out the 3/8 OD hose on top loop as have come to like the Quick connect fittings and the 3/8 hose is almost invisible compated to 1/2 ID sillicon. Am gonna move the 5/8 T at the bottom and put in next to block and see if I get flow through that loop. If it does, will set it up that way.Will be pump-- rad-- T--block-- T--back to pump twice. If not will set it up like I got it with aprx. .25--.30 water going through 2 rads and the rest just 1 rad. The ONLY way is for me turn this puter off and go do it.
Thanks all for the responses and I kinda feel bad about asking for advice and deciding not to try it. It will be a little while before I can get back as last nite I wired the 2 pumps together so would only have one plug and I will test them separately and together(just because I want to know)
. Will have to undo that and set them up. But thank you all and will let yall know the flow rates. But it probably won't be today.
P.S. last nite was the first time I had used MS paint
