Plumbing – home run, remote manifold or other design?
I will be remodeling my home which involves relocation of kitchen and baths. I will be running 1″ copper to the main manifold, and then I will split off into PEX tubing. I’m getting nearly instant hot water in my current home config (<25 runs through 1/2″ pipe). However, I will be nearly doubling the length of my longest runs. In the remodeled home, – The longest run will be ~50′ to the kitchen sink/dishwasher from the water heater – Master bath will be about ~20′ from the water heater – Kids/guest Bathroom will be about 40′ from the water heater Questions: 1) Based on the lengths of my runs, will a home run cause a substantial increase in hot water wait time/waste over what I have now? 2) Is a remote sub-manifold design with hot recirculation in each location (e.g. baths & kitchen) a better alternative? 3) If I go the home run route, can you also incorporate hot recirculation back to the water heater to get the best of both worlds?
