I'm getting ready to do my rough plumbing for the house I'm building. I am a home owner doing my own work. I have this theory about plumbing design as it relates fluctuations in temperature after a toilet is flushed. Does it make a difference what order the fixtures are connected in a traditional trunk and branch system? My theory is that the toilet would "rob" the water from fixtures that are beyond the toilet. Therefore I am curious if making the toilet be the last connected fixture would reduce temperature fluctuations? Or is it just the drop pressure in the overall system that causes the temperature fluctuations? I am aware thermostatic valves and a home run system helps this problem. I'm just curious if there is any benefit to optimizing the order fixtures are connected.
