Yes, that would be better. Otherwise you will have to increase the flow through the house which will just use more energy to pump and put more wear on the system.

I agree. Especially since now we are designing it to be able to pull two buildings on the second line.

If the outbuilding loop is teed in before the house loop (on the single outlet)and if the outbuilding loop starts and stops it will need a check valve in it to prevent the house loop from making it flow backward. If both run continuously then no check valve is needed.

Thanks again guys! I will ponder over all the suggestions and try to come up with a schematic or even a sketch to be sure I am following you all correctly.
On a bit of a side note, can you recommend an easy way to transition from kitek to something that isnt prone to leaking? And are special tools needed to use it? Someone suggested I have to get an expander?? to adapt to kitek.

I've never used kitec but from what I'm seeing online it was just a particular brand of Pex al Pex. So any Pex al Pex fitting should work, I would guess. Readily available from Badger pipe or other online sellers. I'd call badger.
But from what I read the zinc in the original kitec fittings reacted with the aluminum in the Pex al Pex pipe and can permanently damage the piping. ?? Hope not in your case. There are settlements going on.

I think Kitec was the original pex-al-pex. It was 25mm ID and most now is 26mm. I think Badger fittings are actually 25mm because they always seemed too loose and leaked worse on 26mm PAP.
I have been using the 26mm PAP fittings on kitek and it seems to seal better. You will need a proper reamer tool to make them fit. It takes some effort and stretches it a bit but the flat spot in the pipe isn't as bad afterwards.

The original Kitec fittings didn't have the plastic spacer in them so the aluminum was touching the brass. That was part of the problem.

Ok off to search for badger and hopefully find a reamer there as well as fittings. I have a bunch of brass tees and compression fittings for ordinary pex so one fitting to get away from kitek and I should be set.

Thanks RSI.....a google search for OFS brings up a lot of places but none appear to be what I'm looking for.
Can you tell me what OFS stands for?
I found Badger but there doesnt appear to be reamers available there.

So any suggestions for a Canadian source ?
Between the exchange rate and shipping this gets pricey fast.
