Summer Rain

Yes, we did get the sprinklers installed today, miracle of miracles. The trenches need filling in, but Noel can do that during the week.

We started the day with Noel repairing the dirt sieve, which has seen heavy use of late (every time we dig we sieve the dirt for rocks) and was much the worse for wear. He replaced the mesh, strapped the whole thing together for strength, and we were good to go.

New mesh for the dirt sieve

I tested out my water connection, which worked admirably well, though I did get leaks in almost all my capped ends. I've got very poor grip strength, so I usually avoid fastening plumbing by hand.

Attaching to the manifold

The connection to the manifold is remarkably simple. Plumbing in general is like that: you draw a line between the supply and the outlet and that is where your pipe goes.

How the sprinklers get into the manifold

While I made the manifold connections, Noel worked his butt off digging the trenches out, and soon we were able to set the pipes in place and see how it all went together.

Pipe in the trenches

I let the PVC glue set up for an hour, then flushed the pipes to get all the sand and other debris that had gotten into them out before we attached the sprinkler heads. You can skip this step, but then your sprinkler heads will be full of all the random stuff that got in your pipes. I knew we'd gotten lots of sand in more than one pipe, so I flushed the system for a nice long time to work it all out.

Flushing

Then I attached the sprinkler heads and packed them into place with some dirt.

Attaching the sprinkler heads

The heads all needed to be adjusted for spray arc (some 90 degrees, some 360, some 180), and to get the arc pointing in the right direction. Then I just stood there and watched them go for a while.

Adjusted and running!

We still need to make some sort of support system for the manifold, and it's dripping terribly so I need Noel to go through and tighten things up for me or even redo my wraps, but we have sprinklers!

The trenches look like little canals in the photos. It's something amazing to stand and watch the landscape receive water with no more work than turning on the sprinklers.

Will you build a box for the manifold or just a simple frame?

The flushing really filled those trenches up. I should have floated a little boat on there for the photo.

I think the manifold will just end up with a support frame and nothing more, because we plan to put on a deck on the back of the house and that will cover everything up.

what exactly are those manifolds doing?

You mean all the stubbed out connections? They're going to zones in the irrigation system. I just attached the back lawn sprinklers for now because we're doing everything on weekends by ourselves, and I didn't want to make a holy mess of the place.

There are lots of valves and zones because we're dealing with a slow, constant water supply and a relatively large, complicated garden.

The manifold's function is just to distribute water; each zone has a valve controlled by a computer system.
