So this is our suction side of the settlement tank and
if you'll notice I put a little 45 down here to give
me a little kick up toward my trench and I'm using this
black pvc pipe here cuz it gives me a nice sweeping connection so
my water can flow nice and easy in this upward curve.
Hold that for a second.
Now I can set it down.
We're just gonna back fill a little bit around here to stabilize
the settlement tank so we can.
Start plumbing the bottom drain.
When you're doing some backfill, it's always good to add a little bit
of water to help with the compaction.
Hand me that tamper, please.
I got the level still on here so if it gets knocked out of balance,
I can take a look at it and make quick adjustments.
Okay, hold on, hold on.
I'm going to take that around.
As you work your way up, you want to add a few inches of soil,
add a little water, do some compaction.
Our main objective at the moment is to stabilize the unit,
which we've done.
Now we can start the bottom drain plumbing right now.
Wanna take that?
Okay, as you see, I'm just gonna scrape these burrs off of here so
when I go to glue this together I don't have anything holding me back.
We don't want a simple burr like this messing up your glue
connection this far underground if you know what I mean.
All right, let me give you a little explanation about how I got to
be exactly where I am right now.
When you go to do the bottom drain circuit,
you want to get everything in place.
My settlement tank is stationary so I can't move it and
I don't have any play right there.
But I have play back where the bottom drain at.
So what I did is, I put a piece of pipe from the bottom drain,
tunnelled into the wall.
I have an elbow coming upwards and
then I have this pipe that you just saw me cut.
Now I lined it up, I have everything roughed in,
which means I cut all the fittings that I needed and
I kind of just barely pushed them together to get everything aligned.
So now that I've made this cut and cleaned up the edges,
you'll notice that I'll put this sweeping elbow on there, and
I'm right in line with this guy.
And I’ll be able to lift up my bottom drain, and
glue it together just like that.
And I can push everything towards the settlement tank
cuz that’s my stationary piece.
So it’s kind of important.
If you glue this part,
it’d be hard to get this fitting to glue into here.
So that’s the process of which we did it.
Well let me climb out of the hole and
I'm gonna explain to you this assembly that I have up here and
why it's important.
Okay, I want to give you some pointers on this before we glue it
all together because this can go easy or it can go really hard.
And so I want it to go smooth for you.
To give you some explanation,
our four inch bottom drain line is coming up.
Before it connects into the settlement tank,
we're going to have what we call a knife valve.
You can see how we closed it like so, thats the knife valve.
Now what this does is, when we want to service the settlement tank,
we can shut the system down, turn the pond off from the settlement
tank and we can do our cleaning in there.
When it's time to be running we would open the system back up so
we can fill through there.
So this valve's critical to making this easy to clean.
Now I mentioned before, I kinda roughed these fittings in.
I kinda knew what size I needed and so I cut these fittings.
Then I formulated them all together.
And I went down in that deep hole and then I made all my cuts, okay?
So I have a rag to knock down some of the dust.
Typically plumbing on all your PC fittings here.
Give it a little twist as you put it in.
And you want to hold it for a second.
Okay, so,
I can glue this directly into the settlement tank at this point.
And that's gonna be my next step.
