Pump Sugestions

[waynebard]

I have a new boiler i installed along with 5 zones,
it is using a taco 007 for Circulation,
now the system will
function properly if only one or two zones are active.

But if there are more then 2 zones going
at the same time then the 007 will not move enough
water through the system to heat all the zones
effectively it seems.

I have some long runs, one is like over 75 feet.
I need some sugesstions as what pump i can use to feed all 5 zones equally,
i was told that a taco 007 has a higher head pressure
then a b&g 100, i was thinking about a b&g 100,
but i am not sure if it will solve my problem,
i really need some help here.

Thanks for you time, reading this and helping me out.

If you need more detail then let me know.

Should have plenty of head for your job if the longest run is 75 feet. Are all supply sizes the same?
Is the pump on the supply or return?
Is all the air out of the system? I hope you installed an air scoop and automatic bleeders.

The pump is on the return side, the feed is 1 1/2 steel and the return is 1 1/4 copper, i have air bleeder on the water feed expansion tank,
all supply lines are on 1 1/2 by 3/4 tees and the returns are on
1 1/4 by 3/4 tees, all zones will get hot and i have bleed out the system, it just seems to be the pump will not move the water through the system equally, like the zones closest to the return seem to get the most water presure. I am not 100% sure, i wish i could hire a professional to check the problem, but money is a problem and also the fact that i installed the system myself hampers someone wanting to look at it. I have most of the system looped, meaning that the zones goto one end of the baseboard and then loop back thru the same baseboard back to the boiler. So i may have 75 to one end of the house and then looped back, so it maybe like 150 feet total, i was also thinking that the taco zone valves i am using have a pressure lose involved.
