Texas Water Day: Rainwater and graywater harvesting


I was able to spend about an hour at Texas Water Day today, a day-long event at the Capitol o' Texas focused on water conservation. I missed all the speechifying but was able to stop in and chat with the booth people and complain about the size of the urinals at the capitol to random attendees (we're talking ginormous, at least the ones in the annex...). Sorry, no photos. Guys get freaked out when you're taking photos in the bathroom...

I was also able to chat with several folks about other important matters. The City of Austin conservation folks were there, and we yimmered and yammered about pressurized rainwater harvesting and graywater.

On the rainwater harvesting side, we discussed the requirements for reverse pressure zones (RPZs), licensed plumbers, and permits (things I'm not convinced are necessary for a system not even remotely connected to the city's system). The boothpeople told me that the city is considering exempting certain pressurized systems (say below 30 psi, quite a bit below the city's pressure) from the RPZ/licensed plumber/permit requirements. That would be a nice improvement. They're still scared of a fully pressurized system being accidentally or purposely connected to the city water and getting (insert ominous voice here) "water of unknown quality" in their system (of course someone purposely doing this would not be getting a permit to do so...). But I can see why they have concerns. Two fully-pressured systems on site increase the odds of someone screwing up, especially subsequent homeowners (and plumbers) that don't fully appreciate or understand the system.

We also talked about on-site graywater use. The boothers said that the city is in the process (any day now!) of revising those rules under a new "Laundry to Lawn" program where you can just run your waste laundry water out into your yard without the subsurface storage and drainfield requirements. Yippee!!! Too late for us (we didn't build in separate plumbing for graywater), but for subsequent graywater adopters, this is good news.

More about graywater:

       News article about graywater and rules use in Austin.

       City council resolution on graywater.

       Here's a proposal from the City's Graywater External Stakeholders Committee. 

       Some people have said "TO HELL WITH THE RULES!!!".
            They are the few, the proud, the Greywater Guerrillas.

I also ran into a pal I used to work with that is a turf expert, a subject she studied at Texas A and M. There's a lot of people I know that went to college and did nothing but grass, but this young lady truly went to college and studied nothing but grass! After talking about the house and landscaping (and getting reminded that she was a turf expert), she recommended Thunder Turf by Native American Seed. The bride and I have talked about using Habiturf, but it's expensive as hell. My turf-grrl friend said Thunder Turf was the way to go. She even texted me later: "Thunder Turf = Good Stuff".

Several weeks ago I was yapping at an event in Junction, Texas, and went to an after-event wine swig that turned out to be hosted by the proprietors of, you guessed it, Native American Seed! These folks live water conservation and even had their Texas Raincatcher Award, an award passed out by the Texas Water Development Board, proudly mounted on the wall in the living room. We drank wine and talked about grass, rainwater harvesting, and rain gardens. That, my friends, is a good evening (even without the wine).

Anyway, the universe seems to be lining up: THUNDER!!!  TURF!!!

The cool bit of swag I picked up at Texas Water Day was a shower timer from the Texas Commission on Environmental Quality:


I've actually been wondering how long we (ahem...) I spend in the shower. Now I can do some timing! That old-skool grains-of-sand timer above allows five minutes for rub-a-dubbing.

Let the experiments begin!

week 15: the good, the bad, and the ugly


Sorry for the delay in posting: The weekend and the past couple of days have had our free time consumed with house stuff. Truth be told, that's what I should be working on now (but this strikes me as more fun at the moment [and needing to get done...]).

the good

Went out to the house on Sunday after a long but productive 2.5-hour meeting with the cabinet lady. We then spent the next six hours picking up nails, sweeping, and vacuuming the house. It was a full (and hot!) day.

The big news is (drum roll please): The big-ass window in the living room is installed! And it looks quite grand:






The biggish window at the top of the stairs is also in:



as is the storefront frame (no glass yet) for the powder room:



and the side window in the front:



Nice!

Big news on the roof front: We're starting to get a finished (as in there-ain't-no-leaks-no-more) roof! We've been selfishly fortunate that it has been a very dry fall despite predictions of El Nino conditions this fall (El Nino was canceled). In fact, no rain fell in Austin in November, the first time that's happened in over a 100 years.



That white bidness you see here is the roof: thermoplastic olefin, what the cool kids call TPO. Highly reflective (it's white, afterall) and fully sealed (if installed correctly...), it should be a good roof (and better, wethinks, than torchdown).

There's tub in the house:


and there are holes in the LVL beam to run ductwork through:


Those darkish things you see are metal angle irons to compensate for those big 'ole holes in the beam. Helps hold the house up, so that's a good thing. The framer did a great job here: real clean and ready for drywall.

the bad

During week 14 the plumber ran the drain pipes hither and dither about the house. During the past week, he ran the water lines. And it wasn't purdy: There was a herd of stuff that was just plain wrong because he hadn't looked at the spec sheets. The plumbing for the powder room sink was all wrong (including the drain). He plumbed it for a standard sink in a cabinet instead of an in-wall faucet  and wall mounted sink (with the plumbing hidden behind the sink). That's gotta be redone.

Now picture yourself facing the garage. Off on the right side, out of the slab, is a water-supply pipe. Clearly marked on the plans is an outdoor spigot right at that spot where the pipe comes out of the ground. Makes sense: The ground is insulating the pipe, so that helps keep the pipe from freezing (and breaking). What did the plumber do? Ran the pipe up the wall into the attic space, then ran the pipe clear across the front width of the garage, and then back down the opposite wall. Huh? Seems like a freeze hazard to me. Comically (to my eyes) they insulated the pipe. But this is in unconditioned space, so I don't think that insulation is going to do much during an extended freeze. (I say pipe, but technically they run hose these days. It very well may be that the flexibility of the hose is enough to accommodate the expansion of water during a freeze.)

Given how the spigot for the garage was installed, it's good we had a central shut-off valve for the outdoor faucets installed. After discussions with the builder, we decided to install this valve in the pantry. Where did it get installed? In the laundry room. Not fatal. The valve could go in there, but they installed it where the backsplash to the potential bar area is going. Not good.

The plumber ran pipe for the potfiller. Again, he neglected to check the specs and made an assumption that it was a wall mounted pot filler. But it ain't: It's a deck mounted pot filler. Oops. In his defense, I bet 95 percent of America's pot fillers are wall mounted, but still: check the specs, dude. I mentioned to the builder that much of this could have been avoided with a pre-install walk through with me.


Looks like there may be a wee bit of replumbing going on...

the (not so) bad (but prolly for the best)

Our master bedroom door to the outside was installed! But it's the wrong door... After doing so well on the first bid, we upgraded the door to a storefront aluminum and glass door. However, the door we installed is the original one spec'd, not the upgrade. This is prolly for the best since we were having second thoughts on having a glass storefront door in the master. Not that I don't look (fairly) good in my whitey-tighties (especailly after a wax), but (cough-cough) I'm a little shy, so I'm not eager to give the neighbors a show. We'll stick with the door the builder installed and apply the money we save on the change orders.

I have dream of maybe at some point installing an Allandale door made locally (like across-the-street locally) by Crestview Doors, inventors of Door-o-Vision.



the ugly

There be some ugly at the house. I'm learning that some of the practicalities and code requirements result in ugliness. Reality sucks. Some of the issues:

The gas connection to the house has to be toward the front of the house. When the email discussion first when back and forth on this, I was later horrified to realize that I may have agreed to the have the gas connection placed on the front of the house, so I was relieved as heck when I saw that it was just around the corner of the front of the house. Ideally, this would have been pushed farther back, but the builder claims this placement is a code requirement. Regardless, given that it's on the side, it will be easy to hide with either a low (tastefully designed) fence or a shrub. Whew!


Non-centered exhaust vents. This is a view of the powder room looking towards the toilet. That metal box up yonder is the vent. That looks (slightly...) off center. Not the installer's fault 'cause that's what the framing looks like but boo nonetheless. On the other hand, a wee bit of asymmetry may look cool (perhaps balanced by a toiler plunger to the right of the toilet). Why yes, we meant to do that, yes we did.


General infrastructural kookiness. Look at that picture below taken of the ceiling area of the master shower. Holy moly, there's a lot going on up there! That ceiling's got more snakes in it than Samuel L. Jackson's emm-effing plane! Here's a case where the ventilation fan (the square box) could have been centered (ain't no framing to prevent it) but can't because of the need to run the ductwork through the truss. And then there's ventilation ductwork, and water lines and (yet to come) electric wires. Dang. Maybe we need a glass ceiling in here to show this off.


Those aren't the ventilation fans we wanted. Oddly, for whatever reason, the issue that has made me the most angry during the build of the house so far (somewhere between "dang-that-dude's-face-is-really-red" and "smashing sh!t up") are the ventilation fans. I proudly found some swank ventilation fans that had the perfect intersection of price, function, and aesthetics. During the back and forth with the builder and sub on ventilation fans, I asked that they put in the ones we wanted. The builder responded that there wasn't a local supplier for those fans. I responded that they could just order the ones we wanted. And these are not them.

When I first saw these suckers, I coulda eaten a handful of fire ants. Maybe two handfuls. When we got back home, I looked up the emails of what we agreed to on the subcontract. We agreed to "lo sone" fans, and I assumed they were the ones we wanted (we indeed wanted low sone fans [super-duper quiet]). But it turns out "Lo Sone" is a Broan model, so we unwittingly agreed to Broan fans. Irritating, but we don't have much (any?) ground to stand on here (and there are probably more important things to worry about than this [Focus Bubba: Context! Context! Breathe! One. Two. Three. Breathe!).

Nonetheless, I predict we won't have any fire ants for a few years after we move in...

What up, shower wall, what up? The last we left the shower wall, the builder was super nervous about having it only go up eight feet instead of the full nine feet of the ceiling height. We first investigated installing steel posts to support the wall, but the engineer couldn't guarantee the wall would be inflexible. At that point we said "Screw it." and said finish the wall to the ceiling. The architect then suggested that the end of the wall could be carried up to the wall to support it and the rest could be open. Although not as elegant as the original design, we thought this was better than running the full wall up to the ceiling. So that's what we decided. So we were surprised to see plumbing plumbed through the as-yet-unchanged wall. When we mentioned this to the builder, he responded that anything other than a full wall was a bad idea, which is why it's a full wall. Hmmmm... Still thinking about this (and will probably discuss with the architect). While writing this post and looking at the photo, I realized that without that wall, you can't run the water to the tub control and spout very directly because of the big window over the tub. On the other hand, do you need "instant" hot water for a tub?


Where will art thou hang, kitchen pendants? Since electric is coming up next, I methodically walked through the house looking for potential electric problems. And I found them. The most vexing are the pendants for above the kitchen peninsula. The air handler (I think that's what that big silvery box is called) is located in the very place the pendants need to hang. In other words, there ain't no place to put the electric boxes for the lights. Given that that's task lighting, I don't think that lighting is really optional. Not sure what the solution is, although I've read that not having pendants over islands and peninsulas is the new thing. So perhaps we will wind up hipper than we anticipated.


 Closet space? A large part of the infrastructure kookiness is the difficulty in dealing with the HVAC system in the house. As the builder puts it, the HVAC system has been a pain. I had envisioned the ductwork running up the spine of the house defined by the hallway from the front of the house to the master bedroom. Unfortunately, there's something like four solid beams between here and there that make that impractical, so the duct work had to run through the second story attic down to the master bedroom. Only problem: No place to run the ductwork down to the master suite, so we had to give up space in the guest closet (already not very big) for the duct work. Not a problem for how we plan to use the space, but I can already see the House Hunters episode filmed at our house: Hip young couple with 12 children liking the house but then, when opening up this closet, grimacing and making a snarky comment like "Is this where they keep the backup espresso maker?"


Spirited design makes for spirited challenges in installing internal infrastructure.

week 14: MEPing around...


Not much changed on the outside of the house, but there were some subtle changes...


For one, the bride (finally!) has her powder room window:



And the roof lines at the end of the carport have (finally) been fixed:




Much better.

We also now have doors on the garage, although we're hoping that this garage door is here for sizing rather than the final door since we spec'd a fancy-schmancy aluminum and glass door (something we just had a discussion with the builder about).


Most of the work that happened on the house the past week happened on the inside with the MEP: what the cools kids call mechanical, electrical, and plumbing. Actually, nothing on the electrical yet, but the HVAC and plumbing work have started with most of the duct work, vents, and the ERV installed for the HVAC and most of the drain and ventilation pipes installed for the plumbing:






An unintended consequence of having an in-wall drain is the apparent requirement of having a clean-out which, in our case, will protrude out the front wall of the house. :-(  Taller bushes? And lemme tell you, those plumbers aren't delicate when when they work. I bet the stucco guy is going to be irritated when he sees this:


I was hoping that we would be able to avoid the dreaded Medusa's Head of Ductwork, but with all of the solid structural beams criss-crossing the house, it wasn't meant to be... In fact, the difficulties in running the ductwork have led to a $950 change order, a change order that didn't come from something we changed but an unexpected change in the framing required to run the ductwork. Contingency, contingency...



The window (or framing?) guy laid down the base plate for the big honkin' window for the living room. Might there be a big honkin' window in our future this week? We hope so!


We spent a couple hours picking up litter, sweeping the house, picking up nails, trimming the trees, and talking to neighbors. It felt good to do a little "housework". I reckon we'll do some more next week!

week 12: windows, water, wastewater, and whatnot


Three months in: Woo hoo! Every week amazing progress happens (we've been told by folks to not get too used to that as things slow down once work focuses on the interior...).

The big news this week is that the windows arrived! And they look mighty fine. Although aluminum windows from the old days have a bad rep, these are pretty sweet with a thermal break, an Energy Star rating, and nice lines outside as well as inside. And they're recyclable! But hopefully they won't be recycled anytime soon...






In the photo above, you can see the the Hardie board installed on the house where Hardie board is supposed to be installed (stucco will be everywhere else). Also note the black lines on the green panels. The green panels are part of the Zip System, sheathing with built-in moisture barrier on the outside and special tape (that black stuff) to seal the seams.


You can also see from that photo above the face plates on the eaves, also made out of Hardie, installed. They really look sharp.



The garage is fully clad and has its windows installed (we chuckled that the garage windows are double paned...).


And there be Hardie on the south side of the house as well:


The sewer line and water lines are hooked up and waiting for city approval:



Also, the art wall that separate the entry from the dining area is now roughed in:


as is the lowered ceiling above the dining area (done to allow ductwork to jump into the living room):


issues resolved, issues pending, new issues...

We now have the missing window in the kitchen:


The bride is already in love with it. Lets in a little light from the side.

Window X, the window above the powder pooper, is turning out to be a, well, pooper. Unfortunately, it didn't get ordered (the architect uses Window X for window planning purposes [kinda like Planet X: does it exist or not?]; however, it turns out we reach X number of windows in the alphabet, so we really have a Window X). The window only costs about $200 to make, but the one-time fees and shipping add an extra $400 to the cost, and it takes six weeks to get built and on-site). The window is spec'd to open, but we figure that doesn't really make sense with a bathroom window that opens up onto what amounts to the front porch area (Tinkle, Tinkle, Little Star?). Perhaps the architects wanted an opening window because of the thickness of the aluminum on the outside (see second photo in this post). Regardless, we told the builder that we're fine with a (non-opening) storefront window for that location, something that can be gotten locally relatively quickly.


The roofing detail at the end of the carport has not yet been resolved:


Watching this closely since the roof is apparently going on this week. This needs to get fixed cause it looks like ass.

Someone showed up today to start installing weep screed (the metal stuff at the bottom of the outside walls to facilitate drainage from the wall to the exterior):


 and moisture barrier (that black stuff on the lower part of the house):



and herein lies an issue: That don't look right to me. The idea here is that you put two layers of moisture "barrier" up because the top layer is sacrificial (I put barrier in quotes because it's not an absolute barrier; you really don't want an absolute to allow the wall to breathe so it can dry to the outside or to the inside). The stucco bonds to the top layer and compromises the hydrophilic (water repelling) properties of the barrier. As the stucco dries, it retracts a wee bit and creates a drainage plane between the first layer of moisture barrier and the second, thus creating a drainage plane. Ideally one would use a proper drainage plane here (a thin layer of drainable puffy stuff), but a number of folks (including the builder's stucco expert) say using two layers of moisture barrier works (and the Zip System actually constitutes another layer).

All of this is fine, but what I don't like is how the layers are layered. I think that stuff should be layered like this:


with each layer independently shingled upon itself rather than the way it is now (the black lines are the layers of moisture barrier and the orange is the stucco):


which creates truncated drainage planes (not good) and thus, no drainage. This risks compromising both layers. Sure, the Zip underneath is a last chance to move that moisture away from the wall, but then why have two layers in the first place? I ain't no stucco expert, but that sure don't look right. Hopefully this is just a case of a Sunday working not really knowing what he was doing...

coming up:

They still need to install the big ole window in the living room:



as well as a couple of problematic windows, one at the front of the house at the side and the big one at the top of the stairs. In retrospect, these windows probably should have been storefront. The Gerkin windows have flanges at the sides to attach the window to the walls at the sides. For the case at the front of the house and at the top of the stairs, there's nothing to attach to on two to three sides.

We'll also be meeting with the architect, builder, and HVAC sub on Tuesday to discuss duct runs. The architect is calling for 10-inch holes to be cut into the beams, something that's making the builder nervous even though the engineer has signed off on it. Truth be told, it makes us a little nervous too. I suspect that there are several of these cutting-holes issues about the house. Should be an interesting meeting. We're especially looking forward to the architect being there: This will be our first site visit where he's there as well!

moment of bliss:

The dumpster is gone, so now we can get a full shot of the double cantilever. Everybody say "aaahhhhh...."
