I am working on building a new house and have been trying to do my due dilligence to ensure I have a good design that will last as long as the house. Been browsing the forums hear for a few weeks, lots of good information! Just want to cofirm what I have learned, because I am sure it is not 100% yet.
Some Background Specs:
- System will be PEX Home Run, using Uponor ProPEX
- I will be on a shared well, 860ft deep, 5 houses on the well (will be in the well forum later, waiting on more details on the Well)
- Based on a neighbor on the same well, he has been measuring about 50psig on his line from the well, min is about 40psig, max seen is 68psig.
- Will have my own septic (will check that out at a later time) about 2000gal in size
- Well connection is about 40ft from house, will be about 80ft to first tee.
- two story house with 2.5bath, basement will be unfinished but will have a full bath down there as well. master has a shower and whirlpool tub, both full baths have dual sinks.
- will be plumbed for hydroponic radiant heat in slab, but will not be connected initially
1. Sizing of Feed - First thing I am trying to determine the proper size of the line from the well to the house. I am thinking 1". Is there a benifit to 1.25" if the first thing it goes to is a 1" connection on an iron filter (I will be finding Gary later on this)? Once in the house it will run through an Iron Filter, then Tap off to a split - 4port manifold for non-softened water (1") and connection to water softener (1"), split cold (3/4") to manifold and hot (3/4") to water heaters (2 in series, I am sure that will get some discussion) and then on to the hot manifold. It does not seem like 1.25 will gain me anything, or am I overlooking something?
2. Fixture lines - Right now I plan to use 1/2" to all fixtures, but am considering if I should use 3/4" to the whirlpool tub. The longest run is less than 50ft, any issues with this?
3. Pressure - I did a calculation using 40psig as the base and cameup with 34.4psig as a minimum (this does not include the water conditioning losses). I expect to get the same pressure from the well as the neighbor, figured the worst case he saw. Question is what is an acceptable minimum pressure to ensure things are working right? Do I need to consider boost pumps or will this be fine? I know this is considering only one fixture, but want to make sure what I am using is going to work best for the house.
Sorry for all the questions, I enjoy working with my hands, not a professional plumber (use to be an electrician) but am anxious to learn what I can.
Thanks!
