Pool House Expansion Project, Day Forty-Six 26/11/15

It's an Elegant Solution.

As the guys were installing the zinc roofing, we had most if not all of the gap-oh-sis taken care of as far as the flat sheets. Where we had a question was with the roof ridge cap. Well, I found the answer to that question on YouTube (natch). Here's the link to a really elegant solution:

Although they cut the flat pieces of the ridge-cap at a 45-degree angle, I don't think you need to do that. Just cut it straight but about an inch-and-a-half in from the edge, leaving the curved part as in the video. Then trim and bend it the way they do in the video and install as you would normally. Problem solved.

More later. They're working on plastering, textures, and coloring the mortar.

Pool House Expansion Project, Day Forty, 20/11/15

All of a sudden, it looks like a house.

Day Forty, 20 November, 2015

Just This morning, the house magically transformed. All it took was the addition of the zinc roofing pieces to actually be up on the roof.

To get to that point took a lot of work, due, in no small part, to Omar's expert leadership and direction. Here, he's taking a final measurement to figure out the desired overhand of the zinc pieces.
Omar Measuring Roofing Panel Spacing
 Early in the morning, well, around 8:00 AM, the crew is still working to finish the eave extensions.
Working On the Eave Extensions
I just stepped out on the porch of our current house, the Mennonite house, and here's what I saw. The first piece of zinc going up on the roof.
First Panel Going Up
 A little adjustment here and there and it's ready to be screwed into the trusses and cross braces.
Checking the Panel
 Once the first one is up and in position, the others follow along rather quickly, as you can see below.
Three Panels Up
 And, just like that, another one is hoisted up into place.
And Another One Gues Up
Here's a view of the roof from the underside. It's amazing that it's already starting to feel cooler under the roof. That was kind of the idea in the first place. It's nice to see our design actually taking shape and beginning to function the way we hoped it would as we were drawing it in the first place.
Looking At Roof From the Underside
Here, Errol is ready to grab the next piece of zinc as it is pushed up to him. Each piece weighs on the order of 75-pounds.
Errol Waiting For the Zinc
Here they're fitting the underneat foam to the underneath side of the zinc. It actually is adhered to the drip rail, so that it fits snuggly and conforms to the shape of the zinc piece directly above.
Fitting the Inside Foam
The indiviual pieces of zinc, heavy as they are, still have to be manhandled on their way up onto the roof. Even though they're 26-gauge, as they're being carried and positioned, care still has to be taken not to bend or crease them.
Another Piece is on the Way
That piece is working its way up the roof. One slip could spell disaster for the workers down below, so concentration to the task at hand is paramount.
Magically Up On the Roof
And a few tugs to get the piece into the correct position, overlapping its neighbor by about two-inches, it's then ready to be screwed down.
Giving It Some Last Minute Tugs
Even up on the roof, care must be taken so as not to damage the pieces. Once they're screwed down, they then become fairly strong and resistant to damage.
Twisting and Turning It'll Get There
From underneath, watching the zinc move up the roof into its final position, also gives a good view of the diagonal bracing. This really helps make the trusses very rigid.
More Diagonal Bracing
 We pretty much have a roof over the house now.
Almost A Complete Roof
From up on our Mennonite house porch, it looks outstanding. A real roof.

Rotoplas Septic Tank Work and Roofing Zinc Arrives

Day Thirty-Nine, 19 November, 2015

Yesterday evening, Dianna and I cut out about a half-hour early to have dinner with Bruce and Colleen. My last conversation with Carl was that they were going to add water to the Rotoplas and let it sit all night. I told Carl, that if they turned on the water, it was ok to leave with it filling the Rotoplas and that I would shut it down when we returned from dinner.

Dianna and I returned about 7:15 PM or so, and we noticed the hose wasn't hooked up. I assumed they had filled the tank and headed for home.

This morning when I got up, after securing the doggies in their pen, and opening the gate for the guys, I toured the work site, as usual. One thing I noticed right away, was the Rotoplas was a little off-kilter. Not much, but enough that you could tell. Uh-oh, something must have happened. Maybe the thing floated before they could fill it with water.

When they arrived, Carl told me they filled the tank and it started to tilt. They thought maybe it had too much water and became top-heavy.

Anyway, they brought Omar's gasoline water pump to de-water the Rotoplas. But, since it had been about six months or so since Omar had used it, naturally, it wouldn't start.
Omar's Pump Won't Start
They tried several times to crank it, to no avail. Then they added some gas to the carburetor, nope. Carl checked to see if there was a spark, yup, but no go still. Some French aimed at the pump didn't help either.
Best Minds In the Business
I got my sparkplug socket wrench and they took out the old plug. It was wet, so they knew fuel was getting to the cylinder.

Carl and I had to go to Lano's to check on the zinc and I needed to find some staples for my electric stapler, so Carl took the plug along. Long story short, the zinc was fine and ready for delivery, no staples of the correct size anywhere, and the spark plug was the problem.

So, back to the Rotoplas. This photo shows the outfall for the sludge - the solids, etc., that don't get consumed by the bacteria in the biodigester. This is the stuff that the pumper truck has to suck up. Notice the concrete around the cone bottom.
Waste Pump-Out Line
Here's a glimpse into the top of the Rotoplas with the cover removed. They've got the pump piping stuck into the bio-digester innards to drain off the water so they can reorient the tank.
Cover Removed Showing Bio-Filter Media
You're probably wondering what is in the bio-digester, right? You can almost see something between the boards. Well, here's what you see. Pieces of plastic water bottles, chopped up into two- to three-inch pieces.
Chopped Plastic Bottles Form Filter Media
What this does, is exactly the same thing that we did in Olympia with our homemade pond filter. No, we didn't dump trash into our filter, and no one did that with the Rotoplas. What it is, is a way of providing a lot of surface area, besides the tank itself for bacteria to adhere to (the more bacteria, the better, ergo, more surface area is good) and as the poop and other effluvia flow over and through the plastic bits, the bacteria eat most of it, digesting it all. Hence, calling it a bio-digester is correct.

While I was explaining the operation of the thing to Omar and the guys, I thought that some smaller material would allow for more bacteria, which is true for a pond, but probably not so true for something like this that's dealing with turds of various sizes and consistencies, toilet paper, and the occasional dead cucaracha that gets flushed down the drain.

Like I said, the spark plug was the problem. Here's the pump, happily spewing water all over the place so the guys can re-orient the tank and then get it properly hooked up and then marl poured around the tank.
Finally Able To Pump out Rotoplas
Here, they're getting the toilet line hooked up. Looks easy, but it's always a chore.
Connecting Toilet Waste Line To Rotoplas
And, the zinc arrives. It's the right color and everything.
Roofing Zinc Has Arrived
Off-loading the zinc begins. It's heavy (26 gauge), long, and very awkward to deal with.
Beginning Offload of 24-Sections
They have to move it from the trailer over to some pallets to lay it gently down, without scratching it or bending it either.
Set Them Down Gently
After this, there's only one more piece to go. There were twenty-four in total. A real chore.
Nearing the End of the Offload Process
And, there it is all nice and pristine looking. Next to it is the roof flashing pieces and the drip guard pieces. that other pile is the ridge cap pieces.
Nicely Stacked on Pallets
Something else that came along with it, the foam inserts. There's 'inside' and 'outside' pieces. The inside pieces go under the zinc sheets near the bottom of each sheet, while the outside pieces go on top of the zinc up by the ridge caps. They actually go under the ridge caps, but outside the zinc sheets. The whole purpose of each is to keep bugs, vermin, and other critters, like bats, etc., from moving in under the zinc.
Inside and Outside Foam Inserts for Zinc
One thing the guys almost forgot to do, was to count each of the zinc pieces, to make sure we got everything that was on the invoice. It came out right.
Counting the Number of Pieces
Ok. That's it for this episode. Stay tuned for more.
