Middle of the Manifold

This is going to be the most boring post ever, beating out even the endless photos of plants.

PVC work is like that. You spend an entire afternoon cutting large things apart then gluing them back together again in a cloud of toxic fumes. There's no excitement.

I got back from the hardware store and finished gluing the two beginnings of the manifold together like so:

First part of the manifold done

Then I began laying out the plumbing that comes after the valves in the manifold. You may recall that the inside version of the manifold uses the same pieces as the outside version, but in a different configuration, so I laid out two parallel rows like I had for the two beginning parts. Lots of little bits.

Post-valve plumbing

The only really satisfying thing about PVC gluing is that the layout gets smaller as you work, so a large loose arrangement of pieces tightens up to a neat, tidy array.

Beginning gluing

Noel came home partway through this and helped me with the last bit of gluing, when I was ready to give up for boredom and too much fuminess. So now all I need to do is figure out where I want the two manifolds to go, and set them in place. That will happen tomorrow.

Done for the night

PS: greetings to everybody who is coming here from the little mention in the Christian Science Monitor. We're not spackling at the moment, but I'm sure PVC work is right up there on things it is better to watch people do than do yourself.

That's some serious PVC joining. Are there any pressure issues with so many in a line?

That's just a lot of piping. I'm trying to imagine the amount of pipes running around your yard.

No real pressure issues because at any given time, no more than two or three of the valves are open. If we ran them all at once, um, yeah, we would have issues.

Surprisingly, not much pipe running all over the garden. A few trenches, the first of which we've just begun, but much of the pipe goes under the house and then switches to drip mainline when it gets through the wall. The thing is, the yard is a lot larger than it seems, so when you have two zones on each side plus a few extras in the back, you're up to twelve zones really fast.

(Many of the tees in that manifold are going to be capped off in case we need them later.)
