Location of Multi Port Tee for Plumbing

Hello GBA, Zone 2A, I'm replumbing my house, and need help deciding the location of the main multiport tees. There will be 12 lines for the cold, and 8 for the hot. I can put it in the garage right by the water filters and heater, then route all lines up and over, or just put the tee in the attic then route the lines over from it. There is an access panel immediately in front of where it would be in the attic, so access is not an issue. All lines before the multiport tees are copper.

Pros of the in the attic:
Easier routing.
Looks much cleaner in the garage.
Less PEX used.

Getting an accurate price to build

Greetings! This is my first post on the forum; thanks in advance for the help. We are in the early stages of planning our new custom home (in Tucson, AZ, similar climate to Phoenix, so hot and dry with cooler nights). I'm just a person (not an architect, builder, or real estate professional), but have done a lot of research and have done a lot of DIY remodeling in the past.
We've met with two builders so far and neither interaction was the great. I'm looking for advice on how to salvage either relationship or how to avoid these mistakes for the next builder I talk to.

How do I insulate an already framed concrete wall?

Thanks for the amazing posts. I've learned a lot from this site. Here's the scoop. I live in Wisconsin, Zone 6. New construction and a walkout basement with full, 3/4 and 1/2 concrete walls. Builder had fiberglass and poly over studded wood walls and fiberglass only over concrete walls. We had a wet fall and at the end of it, there was just a mess downstairs. I pulled it all out to dry, and there it sits.

Passive house exterior door for reasonable price?

Has anyone come across an exterior door that provides good insulation and beefy frame that's worthy of a super insulated home but comes at a reasonable price? Any suggestions would be appreciated.

Insulation

Would R 32 closed cell foam of 5 in. thick preform as good as R 40 in a fiberglass bat at 11in. thick.

Where to vent the dryer and range hood exhaust?

I am building a house with the dryer and the range located in places where it would be difficult to vent them anywhere other than through the roof or through the vented soffit at the eaves of the house. (It's about a 40 foot run to get to the gable end)

I understand that venting an appliance through vented soffit means that the humid air will likely get sucked up into the attic where you don't want it. However, reducing roof penetrations appeals to me and I am concerned about lint build-up being harder to deal with if the dryer is venting through the roof.

Not enough XPS over roof - should I vent?

I am in the Washington DC area - Zone 4. I just had a 1.5/12 single slope roof framed with 2x8's for a 14x20 new block wall garage. On top of the rafters there is a layer of plywood followed by 2" XPS rigid foam followed by another layer of plywood and then an ice and water shield across the entire roof. This week there will be a standing seam metal roof installed on top.

I have two specific questions regarding efficient home-run plumbing design

My wife and I are currently working with a local design/builder on a set of plans for a small home in Silver City, NM (4B). The main bathroom, mechanical room and kitchen are all grouped together on the 850 square ft main floor. A second bathroom, located directly above the main bathroom, is planned for the 550 square ft loft. The wall assembly will be 2*6, dense pack cellulose, 1 inch of EPS exterior the sheathing, and fiber-cement siding.

Humidity

While I was on the subject originally regarding adding central air to my gas furnace, someone was talking about humidity levels in the winter and how dry you feel at home.
I just realized and was told that whole house humidifiers only work/operate anyway, when the furnace is actually running. Makes sense.
in my opinion, and having a hydrometer to prove it, whole house humidifiers are a waste of money, period.

What do you do when you can't find duct leakage issue?

Conducted an audit today on a manufactured home with a rectangular duct board system in the belly. Duct leakage testing resulted in NO reading at 25 pascals. We crawled under the entire home following the trunk lines and found no visible signs of broken or disconnected ducts that could explain such high leakage. Has anyone out there ever ran into a situation like this? If so what did you do?
