SAFETY FEATURES-ANSI/NSPI-5 Article XV (15) 15.1 Handholds: An in-ground residential pool shall be provided with handholds around its perimeter in areas where depths exceed (3’-6”) three feet six inches. Handholds shall be provided no farther apart than (4’) four feet to include but not be limited to, any one (1) or a combination of items listed in Articles 15.1.1 through 15.1.3. Article 15.1.1 Coping, ledge, or deck along the immediate top edge of the pool which provides a slipresisting surface of at least (4”) four inches minimum horizontal width and located at or not more than (12”) twelve inches above the waterline; or 15.1.2 Ladder, stairs, or seat ledges; or, 15.1.3 A secured rope or railing placed at or no more than (12”) twelve inches above the waterline.
Construction standards: The minimum compressive strength of concrete used in pool/spa shell construction shall be 3,500 psi. The minimum shell thickness shall be (4”) four inches for gunite, (5”) five inches for shotcrete, and (6”) six inches for hand-stacked. Foundations for decks which support other structures shall be designed in accordance with 2004 FBC, R Chapter 4 and the minimum width of footings shall be (12”) twelve inches and all exterior footings shall be placed at least (12”) twelve inches below the undisturbed ground surface. The maximum width/ length of pool/spa constructed under these standards shall be (36’) thirty-six feet.
Excavation Chart As applicable, check one box which represents the worst case site condition for minimum required distance away from bottom of existing foundation and the maximum allowable depth of excavation below the existing foundation.
Interpretation between values is acceptable.
The total depth of excavation (dig-out) is determined by adding ('d') depth of foundation below grade, to maximize allowable depth of excavation below bottom of existing foundation taken from chart.
EXAMPLE: If 'd' equals 7' and the distance from the foundation is 60', maximum dig-out would be equal to 79'.
Print Form Compliance with ANSI/APSP-7, & FBC, R4101.6, shall be determined by one (1) of the following Methods: (Select Method and Provide Applicable Information & Completed Form(s).
1. Maximum Pump Flow: Maximum pump flow capacity of the pump(s), which shall be limited by the criteria of ANSI/ APSP-7 4.4 (e.g., based on the manufacturers pump flow curve using the listed maximum GPM/gpm (gallon per minute) determine the pipe sizes per Table-1; and select component(s) based on manufacturers listed flow rate for the component, which are acceptable for use at the maximum pump flow gpm rating. (Use Simplified TDH Form for listing results; and for listing the components/manufacturers information)
2. Simplified TDH Calculation: (Use Simplified TDH Form for Calculation(s); and list results with the selected components/manufacturers information)
3. Complete TDH Calculation: (Attach Complete Calculation(s) and use the Simplified TDH Form for listing results; and for listing components/ manufacturers information) This information is based on each pumping system provided, and the total maximum flow rate possible in the system; if more then one pump is provided in the system the total possible gpm flow rate of the combined pumps must be used in the calculation.
If there is more then one pumping system available, such as two separate isolated pumping systems, one for the pool and the other for a spa, then each separate isolated system would require a calculation for determining compliance.
When the piping system offers multiple operational configurations the TDH calculation shall be based on the lowest TDH produced by any system configuration possible (e.g. if there are features that are intermittently entered into, or removed from, the system flow; the pathway that produces the least TDH shall be used for determining Velocity flow-rate).
I. Selected Pipe Size to be used for: (Nominal size in inches for schedule 40PVC) (a) Branch piping size ____ (Maximum Flow-Rate allowed (in gpm) _____ to maintain the maximum allowable Velocity flow rate in pipe of 6fps from Table-1) (b) Suction piping size ____ (Maximum Flow-Rate allowed (in gpm) _____ to maintain the maximum allowable Velocity flow rate in pipe of 8fps from Table-1) (c) Return piping size ____ (Maximum Flow-Rate allowed (in gpm) _____ to maintain the maximum allowable Velocity flow rate in pipe of 10fps from Table-1) Table-1 Pipe Size Maximum Pump Flow-Rate Allowable (in gpm) to Maintain Maximum Velocity in Pipe (in fps) (inches) 6.0 fps 8.0 fps 10.0 fps 1-½” 37gpm 50gpm 62gpm 2" 62gpm 82gpm 103gpm 2-½” 88gpm 117gpm 146gpm 3" 136gpm 181gpm 227gpm Example: 2" SCHEDULE 40 PVC pipe is acceptable for use with a maximum pump flow rate of 62gpm and still maintain a maximum velocity flow of 6fps.
The maximum pump flow rate is based on the manufacturers flow rate chart @ a specified TDH pressure for Method 2. & 3. (Or the maximum flow rate for Method 1.).
Using Methods 2. & 3. If the TDH pressure is reduced, it changes the pump flow rating, and the pump may not work for the applicable velocity flow rate.
II. TDH (in feet of Head) ___ (Method 1: Enter Zero TDH) (Method 2: Enter Simplified TDH Calculation from Work-Sheet) (Method 3: Enter Complete TDH from Calculations, Provide your calculations and adequate information listed on plans for verification of derived TDH) III. Selected/Maximum Pump Flow Rating (in gpm) _____ (Per Pump Manufacturers pump curve Data; however, pump gpm flow rating can not exceed the maximum flow rating per Table-1 for pipe size selected, or any other components listed maximum design flow-rate; Additionally, your design pump flow rate should be of sufficient capacity for operating all included features in the pumping system; and for maintaining maximum 12hr turn-over rate).
IV. Pool-Water Turn-Over Rate in hours Calculate pool volume in gallons/divided by the System Pump Flow-Rate (in gpm at the specified TDH and divide the answer by 60 = Turn-over Rate in hours (Must not exceed 12hrs); you must maintain a minimum flow rate of 25gpm per skimmer, without exceeding the Velocity flow rate of selected piping size.

Total of (b)+(c) = ____ Simplified TDH for Piping (Add piping TDH to TDH rating of filter and other rated features such as Heater, Automatic Chlorinating system; Etc.; to finish calculating the Simplified TDH for system) Table-2
3) Selected Equipment Make/Model/Flow-Rate/Head-Pressure (Provide Manufacturers Make/Model/Flow-Rating/Head-Pressure rating for items used in TDH calculation; e.g.; Filter, Heater, etc.) Filter _________________________________________________________________________
