Supply Lines



This is PEX tubing. We are using this for our plumbing supply lines. PEX is great stuff.



This is a sleeve for the PEX. One thing that is bad for PEX is UV rays so it must be shielded. Also, the blue designates it as a cold water supply line.



All those lines are connected to a manifold and go to sinks, showers, and toilets.


Under floor electric


We installed conduit along the stem wall under the Ledger. Underneath every outlet in the house is one of those boxes.


Here is the wire that we pulled through all the conduit.




This is a point where everything comes together or crosses. Our main panel will be where the grey conduit is sticking up. The white PVC is the sleeve for the propane line. The black ABS is a drain line. The black coil on the wall is our phone line. This area is all filled in now. 

Septic Tank

If you remember way back to my first blog entry about the Perc Test. Well, this is what that test was for. We got our Septic Tank. 


Here it is in two parts on the truck. 


This is the bottom half of the tank in the hole. 





Here is the top after being joined to the bottom and some back fill. 



This is the leach line it is 68' long. We had rock left over from the rock we had delivered for under the house. This was a good thing as it was perfect for leach rock. 


Gas Line



We don't have natural gas in our area, but we can put in a propane tank. Here are the gas lines.



This is a tee in the line. The PVC is just a sleeve to help protect.



Yep, They came all the way from Thailand.

Underground Plumbing


We got to start on plumbing last week.


An assortment of fittings. 45's, 90's , couplers, tee's, reducers, and more.


Drains and vents from above.


Here it is from below.

Floor



The lumber has arrived and we have been busy getting started on the floor.

Glulam beams on the far left in the wrapping. The shortest was 16' the longest 32'. Next pile over are the joists. Truss joists on the bottom, up from that are the 2"x10" and 2"x12" joists. The green pile is treated lumber for the ledgers, 3"x12" and 2"x12"


Two days to put all the Glulam beams in. Kristi operated the excavator and lifted them all into place. Every beam needs to be cut and shaped to fit. Holes need to be drilled for bolts.



The build team. We have hangers nailed on the beams. The ledger is still missing from the back wall, you can see it on the left. Some of the truss joists are in.

Rocks

We are building a house with a passive underground climate control system. There are actually many different ways of doing this, all with their own unique features. Our system is pretty simple. We dug down three feet into the ground. Our stem wall extends two feet above the ground. This area was filled with 24 inches (290 tons!) of smooth river rock. We built vents in the stem wall on all sides of the house to allow fresh air into this space. The air is cooled under the house and pulled up through floor vents as the hot air is pulled out through exhaust vents in the ceiling. As I said, there are many variations to a system like this depending on your homesite, climate, materials available and so on. Operating our system will take a little trial and error, but should be pretty easy. It basically comes down to opening and closing vents to adjust the temperature in the house. Anyway, the rocks got here a few weeks ago thanks to the guys from Cemex. The rocks we got are a byproduct from the production of cement. A cement plant is basically a mining operation. As they screen material they are left with rocks about the size of a tennis ball to a small football. The cement company has no use for these rocks and they just pile up. These rocks are perfect because of the small air spaces they create together. I expect the majority of our cooling to come from our passive system, however we are building a home in a very hot climate and it is likely that we will need air conditioning for some additional cooling. We will see how the passive system works and go from there.


The rock arrived via dump truck. 300 tons total, 19 loads.
