This video demonstrates a complete dry-fit installation of a one-tier AWS waterfall system in its two-piece (bottom-and-top) configuration. The instructor walks through marking the center point, setting the base panel first, then lowering the top piece which keys into the base like a puzzle and only fits one way. Critical steps include maintaining a cement gap between the two pieces to protect back veneer, reading the letter-number-alignment marking system on every panel, connecting bonding wire to the pool bonding system, and pre-positioning the plumbing coupling before setting the top piece.
What You'll Learn
- Mark the center point of the feature length before setting the first panel; the base (bottom) piece is set first in cement, centered on the footing.
- The top piece keys into the curved seat of the base piece and only fits one way — it was formed and poured together with the base in the factory.
- A gap must be maintained between the back of the top and bottom pieces; in a real installation cement acts as the spacer — in a dry fit, wood spacers substitute to protect the back veneer from chipping.
- Every panel carries a letter (location), a number (orientation), and alignment marks in red crayon — matching all three eliminates placement errors across the full system.
- Each panel includes a built-in bonding wire that must be tied into the pool bonding wire; it is routed through a joint and covered with cement to remain hidden.
- The plumbing coupling at the top of the base piece should be dry-fit onto the pipe before lowering the top piece, using the pipe as a guide for alignment.
Frequently Asked Questions
What is a two-piece AWS one-tier system and how does it differ from a single-piece system?
A two-piece one-tier system has a separate bottom panel and a top waterfall panel for each section, rather than one combined unit. The two pieces are fabricated together at the factory so they form perfectly and only fit together one way. This configuration handles wider or taller systems where a single unit would be too heavy or large to maneuver.
Why must there be a gap between the bottom and top pieces of the AWS two-piece system?
A cement gap on the back side of the joint prevents the veneer on the back of the top piece from contacting and chipping the veneer on the bottom piece during setting. In a real installation the mortar bed creates this gap naturally. In a dry-fit demo, wood spacers substitute for the cement to demonstrate proper clearance.
How do the letters, numbers, and alignment marks on AWS panels work?
Every panel has a letter indicating which location in the system it occupies (A, B, C, D, etc.), a number indicating its orientation, and alignment marks in red crayon that must line up with the adjacent panel. Matching all three on every piece eliminates guesswork and ensures the system assembles exactly as designed.
How is the bonding wire handled during a two-piece AWS installation?
Each panel has a bonding wire built into its rebar cage. During installation the wire is run through a joint, tied into the pool bonding wire that runs around the pool perimeter, and then covered with cement so it is hidden under the landscape rock. Both the bottom and top pieces carry bonding wires.
What is the correct order of steps when installing an AWS two-piece one-tier system?
Mark the center point, set the bottom base piece in cement on the prepared footing, dry-fit the plumbing coupling onto the pipe stub, then lower the top piece into the base seat using the pipe as a guide. Once all panels are set, point all joints at the same time for a uniform appearance, connect bonding wire, and flow-test before finishing the landscape.
Video transcript
Today, this is gonna be used to just dry we're gonna do an instructional video of a dry fit installation of a two of a one tiered, AWS system that is, two part. Okay? As a bottom and top, and it's got, I think, four four panels on the right and four panels on the left, a total of 10. So it's three and a half foot high, and it's, 30 foot wide. So we're gonna show you step by step.
Right? So the first step is we're gonna set this base piece right here. Now, obviously, on a real pool installation, you're not you don't need this big concrete pad. You just need the proper footing to accommodate the system, and that will all be also be included in your AWS packet, the footing detail. Alright?
So we're gonna get rocking and rolling. Alright. So we set this first piece, and the first thing you wanna do is you wanna mark your center point. You wanna know the length of the feature, mark your location, mark a center point, mark the center of that, and this way you have the proper location of where to set the first piece. Okay?
That's the first thing. Now we set that here. Now this is all Gen Drylade because it's a demonstration, but it was a real install. You would put cement down and then set the piece. Okay?
And then point everything. Alright? And then you have a little bit of discretion as far as how far over the edge you set it. You can set it back a little bit, forward a little bit. That's fine because the top piece has a cantilever on a foot, so you're okay.
If you have a tile line there, you wanna be careful. You know what I mean? Not to damage the tile. Take your time and install it and just delicately set it down. Alright.
So now the next you're gonna see our guys move it if they're gonna put the top piece of the, waterfall paddle. Okay? And they're gonna set it right here, and you're gonna see it's gonna sit inside here. It's like a key, right, where it kinda fits right inside. Alright?
So that's the next step. You saw the lifting points here that they used. They disconnected them. Everything was good. So now we're gonna set the next piece.
Alright. So the next step is we're gonna bring this piece in and set it. Now when we fabricated this, you saw in the shop. This bottom and top were built together, so they form together, so they fit perfect. Now the goal is you wanna have a gap between the bottom one and the top one.
So the idea is you would put cement down. You put cement down all the way across here, and then when the top piece goes in, that cement acts as a little bit of a buffer. Okay? So it keeps a little gap on the back side. If you put this in dry with nothing, then the veneer on the back, on the top, and the bottom might hit, and they might get knocked off.
Alright? So we're dry fitting this. We're not installing this with cement because it's a demonstration. So what we are gonna do though is we put these in. These act as spacers, these little pieces of wood.
They replace what the cement would do if you were doing a full install. Full install, you'd have cement here and the cement would act as a spacer. Therefore, when you get done the cement install, there's a gap on the back, and they just fill that out with cement. Alright? So that's what we're doing here.
We're putting these wood in to show you get dry laid to maintain a gap so the veneer don't get knocked off. But in a real installation, you wouldn't have this wood. So as you can see, we set the set the top piece right on top of the bottom piece, and it's set inside. There's a curve on the bottom. This top piece sits inside, and it only goes one way.
This is all built together. We formed and poured this all together, so it only goes in one way. Alright? So you can't make a mistake. You could see.
It fit in real nice. You have a level concrete pad. These two pieces were built on a level surface, so there's a pitch built into this front of this waterfall. Slightly pitch forward to create a nice flow. That's built into the build.
Okay? So now you can see now when we get done, there'll be some cement work to do. Right? You do some cement work all along here and point it. Now we didn't point the front of these rocks, because the idea is when you point in the joint, you point it all together.
Okay? Now what we did do, we pointed the top, okay, with cement so that we could test it. Right? We wanted to fill that all in real nice so we could test it. Right?
So when we run it, we know it'll it'll flow properly. So we we pointed the top and the back, but the front, we did not. So when the installer installs it, they'll point everything all at the same time so it'll look nice and uniform. Alright. So every one of these panels has a bonding wire built into tied into the cage.
Right? So you got one on the top, one on the bottom. So the idea here would be this. Right? There's a stool joint here.
So you would take this bonding wire, you'd put it in this joint right here, and you'd run it down, and you would tie it into the bonding wire around the pool. Right? So this goes in here, gets put in there, and then you cement over top of it so you don't see it. Right? Same thing here.
This bonding wire will get tied into the cage, and there'd be a wire going around the cage. So these would tie in, and then ultimately, there's gonna be a boulder here, so you wouldn't see the bonding wire. That's the idea. Right? You have it on each side, but you won't see it because this will be all boulders going across.
Fit this in, put it down, cement that over, set your rocks, tie the wire to the cage or excuse me, to the bonding wire, and you're properly bonded, and you don't see it. Alright. So you could see the plumbing is building here. You see the the couple here. This goes into the waterfall.
So the idea is that your plumbing line would run to here, and, obviously, there wouldn't be a concrete patio. You would run your plumbing line up here and glue it into here, and then you fill this whole thing with cement, and the AWS system comes with four or five pieces of veneer that are already custom fit and numbered. One to five. Right? One, two, three, four, five.
So you just put some cement in there, and you put each piece of stone, do a little bit of pointing, and then do all this pointing along here, and then you're good. Across the board, everything would be nice and uniform. Alright. So one thing you might wanna keep in mind, when you set this top piece on top of the bottom one, make sure it's snug up against the curve as much as possible. If it's too far forward, you're not gonna be able to get your pipe because the pipe will be over top of the bottom piece.
You won't be able to fit the pipe, and that's kinda what happened to us. You could do one or two things. Number one is you can make sure that it's cinched up to the back, or before you set this, put this pipe in. Dry fit it when it's still in the air. Dry fit this pipe into the hole.
Boom. And let it sit dry. And then when you put this thing down, use the pipe as a guide, you know, then you guide the pipe down into the hole. This way you know when you set the top piece, it's gonna you're gonna retire plumbing in real easy. Alright.
So as you can see, they set this, letter d panel. Right? So everything is lettered. Every panel's lettered, and everything's numbered too. Right?
So two goes next to two, so you know what goes where. This little filler piece was part of it, so it's all clear. Okay. You can saw we set this in place. No problem.
And then we unscrewed our lifting points. Now this is pinned because we're gonna have another rock that's number 18. It's gonna go right here, and it's gonna sit on top of this pin, and that'll get mortared in too so that can't go anywhere. Alright? So if you look close, so you've got the letter telling you where where it goes.
You've got the number telling you the orientation. Now we have a lift, we have a, alignment mark which is in, in this case is in red red crayon. If you look real close right here, right there, there's two alignment marks. So if you align the red marks and you get the right letter and the right number, can't go wrong. And that's the way the entire system is designed.
Alignment marks, letters, and numbers to know exactly how it's put together. So as you could see, the guy's got this whole one-sided in in half hour or so, something like that. Like I say, everything is numbered in letter. Right? Let letters are where the pieces go.
See? A b c d e. Right? So then it's, you know, continuing letters all the way down. On your, the documentation you get with the system, it shows those letters, and then everything's labeled.
And then right here, like we say, this shows orientation. Right? One one one. Right? 888.
So it shows you where the filler stones go. And if you look a little close, every one of these has alignment marks. So you know how it's oriented. Right? So now granted, this is crushed stone because I said this is a a demonstration of how to install it.
But in a real pool, that would be all concrete. But this was built on a level concrete surface. So when you install it, if it's on a flat level concrete surface, it's gonna lay out the same exact well, the pitch, the level, all that good stuff. Alright. So this is coming along nice, and now the boys are gonna work on the other side.
Alright. So you can see this one of the lifting points. Now what could happen? This might happen throughout the project. Something might crack.
Right? Either something might get whacked, a guy might whack a piece with a stone, but all this stuff's pinned in. But you might have a situation where something gets during travel, transportation, installation, some of the mortar gets beat up or cracked. Right? Like, for example, right here, when we were setting this, this anchor point either hit here or something happened where it whacked this rock and a little bit of the mortar cracked.
Right? So the mortar cracked. Okay. Not the big deal. You just chisel it, plus this mortar's fresh because we just did this.
Right? Normally, would wait. Right? So if that happens, you just chisel all this out in here, chisel it out, and point it just like you would point the rest of it. So it's an easy repair.
You got plenty of cement or or dye with you, and and if it's if you do that, that could happen. If a spot got missed or a spot got cracked, chisel it out, repoint it, good as no. This is pinned. This is secured, this pinned, and this rock has a hole in it. So this is designed.
You pick this rock and you slide it on, and then you put a little cement in here and you set it. So this rock is designed to be in this space except it is pinned. Okay? So it isn't gonna go anywhere. So we'll we'll we'll show you guys how to set it, but again, you would dry fit it, put some cement around it, reset it, and then point it, and the same thing with this one over here.
That's what we did over here. Okay? So anytime we have rocks that are off the ground that are filler rocks like this, they will be pinned so they can't go anywhere. Alright? So you can watch our guy doing it.
Alright. So we're kinda done dry fitting this, this, US system. Now, obviously, when you're doing on a real install, you're setting everyone in cement, and now you would start to point it, right, between all the rocks. Take your time. Do a nice clean job.
Right? It took us about two hours to dry fit this whole thing all the way across the board. You know what mean? You might have another couple hours to, point it. So this is kind of dry fit.
Now the next step is we're going to test it, and we're gonna turn it on, make sure the flow is perfect, confirm that it's not leaking, take some photos of it running, and then the next step is to palletize it and, build some custom pallets, palletize everything, secure them, and then it gets shipped to the job site for another beautiful install.
