Zero Edge

Water Meniscus

The water meniscus is the curved surface of water in a container caused by adhesive forces. Let's apply this to a pool. The water level at the edge of the pool will be higher due to these adhesive forces, creating a meniscus.

Wind speeds will affect the amount of meniscus required. The meniscus protects the zero edge or the exotic edge from blowing dry. It’s important to set the customer expectation on how the zero edge will hold up under certain wind conditions for their project. For example, it will increase the budget to design the system to operate in 12 mph wind.
under 6 mph winds: 1/8” meniscus
6-8 mph winds: 1/4” meniscus
Rule of Thumb: 1/4” meniscus requires 7 gpm per linear foot
10-12 mph winds: 3/8” meniscus
Rule of Thumb: 3/8” meniscus requires 13 gpm per linear foot

Notes on 2/29/24 w/ Chris Walton, Jack Spellman, Adam P, and Lee Russell
Lee Russell ​
Friction Loss PVC Charts
8” PVC
5.94 feet per second @ 950 GPM
Since it is under 6 feet per second, this means that we can use it for both the suction and discharge side of the feature
Waterproofing
Does not recommend basecrete currently as they are having some bonding to itself and temperature
Wait about 2 or 3 months until you get it
He would recommend doing Permacoat
Color of interior finish
Chris recommends Caribbean Blue
Perimeter Zero Edge Material
Dekton
2CM
Or
Granite
3CM
Misc Edits to Existing Drawing
8” beam for zero edge behind trough
Redo trough around spa to work with champagne spa
Prestige project, show this detail - Harrington PDF, he said would send this to Jack at 2:32:00 via Pratt guys email to Jack
Misc
Make the gap larger, 5/8” (On a customers pool, make it narrower)
Want to know the total gallons in the top 1” and top 4” of the pool
Autofill on Surge tank, bottom draw of that freeboard. Jandy LevolorK1100 electronic auto fill
Always operate as approximately 6-8 ft per second for plumbing, refer to Friction Loss PVC Charts
Autofill
Jandy LevolorK1100 electronic auto fill
Freeboard (Drawdown)
Total Gallons of Freeboard
Water in Transit and Displacement
Those 2 things above are what you take into consideration to calculate freeboard
To calculate Freeboard, you are taking (2) things into consideration
We will need to determine what our minimum depth is and maximum depth is inside of the cistern tank in order to properly install the Jandy LevolorK1100 electronic auto fill which this will be taking the freeboard (Water in Transit and Displacement) into consideration
Pumps
Spec Pumps
Titan 95 Pump, single speed (We do not need a variable speed)
4” in and 4” out
300-500 GPM with approx. a 5-7hp pump
Need a pump that does approx. 450 GPM each, will put us at about 900 GPM total
Meniscus
3/8”
12-15 MPH Winds
13 gallons per linear ft
1/4”
6-8 MPH Winds
7 gallons per linear ft
1/8”
3-5 MPH Winds
3 gallons per linear ft
Zero Edge Beam
16” thick from the waters edge
16” beam
Pool
Linear Ft of Perimeter (Weir Edge)
119’4”
Meniscus: 1/4”
Gallons Per Minute
835 GPM @ 1/4” Meniscus @ 119.33’ linear ft
Pumps
(2) Pumps
Titan 95, single speed (We do not need a variable speed)
Install 2-Way Butterfly Valves
Install them on the discharge side (we can cam it down so it doesn’t operate at 100%)
Chris Walton is saying this is better for the pump to actually give it a little bit of resistance
Creating artificial head pressure
Spa
Linear Ft of Perimeter (Weir Edge)
Inside: 28’
Outside: 36’
Meniscus: 1/8”
Gallons Per Minute for Perimeter Overflow (This has nothing to do with the GPM for the therapeutic jets)
Base this on the exterior perimeter, not the interior dimension
108 GPM @ 1/8” Meniscus @ 36’ linear ft
8 Jets Total
20 gallons per minute per jet
160 GPM for spa jets
Heat Source
Electric Heat Pump
(2) Pumps
Way more efficient for our clients
(2) Main Drains (Maybe we use the Pul Drains)
(1) For Therapy Jets (Non heated as this will not pass through the gas heater)
(1) For the Heated Footwell Return (Heated as this WILL be passing through the gas heater)
Spa Mode
When the Spa is in the normal Spa/Recirc Mode
Water will Pull from Spa Main Drains and Return to Heated footwell return
Heating the spa from the bottom up is more efficient. Heat radiates & rises, so installing the returns in the footwell of the spa makes the most sense as this is the most efficient.
Pool Mode
Spa Jet Pump will be DUAL PURPOSED to be the Zero Edge/Champagne overflow pump on the spa while it is in “Pool Mode”
Suction Side
Switches from the main drains in the spa to the main drains in the Cistern Tank
Returning Cistern Tank Water to the Spa via Floor Return for the Champagne spa, thus adding to the overflow of the pool as well (Really this would be adding 108 GPM to the Zero Edge of the Pool)
Maybe we use a 3rd PUL Drain as the Return line for the 108 GPM
Discharge/Return
Actuator Valve on the Discharge/Return Side of the Spa Jet Pump
So now, instead of returning to the spa jets, it is returning to the footwell returns that your circulation pump heats the water
Pumps - (4) Total
(2) Zero Edge Pumps
5-7 HP Pumps from Spec, approx. 500 GPM
Chris Walton said he would love to be in the meeting with Spec Pumps and would absolutely love to join in on it once we get something set up with Spec
(1) Recirculation Pump w/ Filter
This is the Pool recirc Pump. However, this will also be the pump to provide the heat (gas heater) when the spa is in Spa Mode (This will not be returning through the spa jets, this will be providing heat through floor returns)
This will also provide the water source for the Laminar Deck Jets
(1) Spa Jet Pump
This will be utilized for the (8) therapy jets only, this will not be passing through the cartridge filter or the gas heater.
(8) Therapy Jets @ 20 GPM per jet = 160 GPM
This will also be DUAL PURPOSED to be the Zero Edge overflow pump on the spa while it is in “Pool Mode”
Refer to the following Drawings
Rewa Plans (Pool Spa Combo, Just the spa has the zero edge, but the set up for the dual pump system shows us the thought process)
Suction Side
Switches from the main drains in the spa to the main drains in the Cistern Tank
Returning Cistern Tank Water to the Spa via Floor Return for the Champagne spa, thus adding to the overflow of the pool as well (Really this would be adding 108 GPM to the Zero Edge of the Pool)
Pool & Spa Plumbing
Blow up Detail of the Spa
Plumbing in the Spa
This will help us understand how we want the plumbing ran so the guys in the field understand how we want the plumbing ran
Add (2) Cleaner/Vacuum/Suction Lines TOTAL, (1) in the Cistern Tank and (1) in the Main Pool
Plumbing Returns (To main Pool from Equipment)
Need to Supply the Pool now with 950 GPM
Returns to be located on the lower portion of the walls (Not on the floor or else you will see the turbulence on the surface of the pool
Pul Products
Use their main drain as it has a 4” inlet (34” x 1”)
16” depth main drain
Just increase the thickness of the shell to 16”
See Diagram picture that Chris originally texted Jack back on 2/29/24 and Jack then sent via text to Adam on 3/4/24
Out the (2) Pumps, discharge size with 4” lines
As soon as these (2) pumps discharge out, ’T’ the (2) 4” lines into (1) 8” line
8” Return
Run to and Joint/Split to back Center of Spa
Split off to (2) 6” Lines to run on either side of Pool
Split off the 6” to (2) 4” Lines (One 4” line for each Return which we will be using the PUL Pulcollekt LD1
Zero Edge Plumbing (Returns to Cistern Tank)
Zero Edge GPM
835 GPM Pool
108 GPM Spa
943 GPM Total
Round up to 950 GPM
58 GPM MAX per 3” Drop Down Pipe
16.4 3” Drop Downs = 17 Drop Downs
However, we are going to split equally on each side, so we need a even number = (18) 3” Drop Downs
Add (1) Extra 3” Drop down on either side to serve as a ‘Studor Vent’, however, it will install no differently as all the other 3” Drop Downs as technically each 3” drop is also the studor vent.
(20) 3” Drop Downs total
(10) 3” Drops on each side of the Pool
6” & 8” Balance Line
3” drop downs will tie into the balance lines
Tie (5) of 3” drop downs on 6”, the last (5) of 3” drop downs to be on the 8” and the 8” line will return all the water back to the cistern tank.
All 3” drop downs will be on the (2) main straight sides of each pool. We do not need the 3” drop downs where the spa is
Min. 24” Spacing between 3” drop downs
Install the Suction/Main Drain within cistern tank approx. 6” - 12” off of the floor to help prevent debris from sucking through the main drain
Main Drain Plumbing (In Cistern Tank)
Code
A Cistern Tank is a Non Swimmable Body of Water, therefore the Code of the main drains do not come/play into effect as it is not mean to swim in
Now if it were designed as something like Davidoff where it is meant for you to swim in, the following would come into effect
Then we would need the (2) main drains or 2 Devices in addition to less than 1.5ft per second
2 Devices below
anti entrapment pool drain cover (anti vortex cover)
Anti vacuum breaker line (Vent Line)
We need to only have (1) Main Drain Line (Home-Run) to pool equipment, 8” Line (Suction)
Create a Manifold back at the Pool Equipment, increase pipe size to 10” for the last 6’ - 8’ as (3) Pumps will be pulling from this
(2) Spec Titan 95 Pumps for the Zero Age
(1) Spa Zero Edge / Champagne Spa Pump @ 108 GPM
Adam has a theory that the size of the cistern is the cubic inches equal to the number of gallons overflow per minute
Paver Deck
Chris Walton thinks it would be beneficial to actually slope the deck back to the Pool to help save and conserve water. (This is like against the common pool practice)
Chris is saying with todays sanitation systems, we are perfectly fine with doing this
This will help save and conserve water
