Greetings, I'm a DIYer looking at replacing my aging cast-iron (post-meter) residential supply line. Currently, there's a PVC tee inline between the meter and start of the iron pipe feeding an adjacent irrigation manifold cluster.

I'm planning on re-plumbing the house supply with 1" soft copper and would like to put in a copper Tee at the house side and re-locate the irrigation manifold up there (and then patch-in runners down to the the branches leaving the current location of the manifold.

I think I'm okay with respect to flow/resistance, etc. I want the manifold up near the house for cosmetic, access, and future expansion purposes. Any major issues that you folks see with this plan?
