Geothermal closed loop configuration layout
I just had an Envision WaterFurnace installed. The furnace required 6 - 200 ft loops installed an when they connected them they put a Tee in the 1 1/4" header pipe and split feeding the loops so 2 are on one side of the TEE and 4 are on the other side. I have a diagram I can send in PDF format.

|---|----Tee--|---|---|---| Feed
|---|----Tee--|---|---|---| Return

The "Tee" makes the connection to the pump in the house.

I have not seen this type of configuration before and was concerned about the efficiency of this configuration. Normally the vertical loops are fed from one side and returned on the other to equal balance and use all 6 loops. In my case, I'm worried that the loops at the ends are not going to be used much and the one closest to the TEE will be used the most.
Can you please comment on this configuration? Please let me know if I need to provide more information.
