Hi All, I am replumbing my entire house, planning on using PEX. I am on a well and will be installing a new tankless water heater and whole house filter. I guess I want to make sure that when it comes to the flow of the water from the well to the faucets that it goes through each element in proper order (if there is one). Here is my original thought, starting with the well: 1) Water pump (obviously) 2) Pressure tank 3) Whole house water filter 4) Hot water heater 5) PEX manifold 6) Water lines, Faucets, etc. Does that seem about right, or should I re-arrange anything? Thanks! tom
