All of the plumbing was roughed in this week. The drains, venting and toilet flanges were set. For maximum efficiency we have a stacked plumbing wall that services all three bathrooms as well as the laundry. A Marathon hot water heater was installed into a system which utilizes excess heat from our geothermal heat pump. To meet the requirements set by LEED for Homes, we insulated all the supply pipes and kept the runs under 20’ from the water heater.
