| | 1) THE SUBMIT TWO COPIES OF THE MANUFACTURER'S |
| | SPECIFICATIONS INCLUDING THE PUMP CURVE FOR THE 2.5 HP |
| | SWIMMING POOL PUMP THAT WILL BE INSTALLED. CITY |
| | AMENDMENTS 107.2.1.3 |
| | THE PUMP CURVE THAT WAS SUBMITTED HAS BOTH THE 2 HP AND |
| | 2.5 HP PUMP CURVES MARKED. THE 2.5 HP SUPERFLO PUMP |
| | APPEARS TO BE A SINGLE SPEED MODEL BECAUSE A LOW SPEED |
| | PUMP CURVE IS NOT SHOWN ON THE CHART FOR IT. PLEASE |
| | CORRECT. |
| | |
| | 2) SHOW COMPLIANCE WITH ANSI/APSP-7 2006 SECTION 4.4 |
| | WHICH LIMITS WATER VELOCITY TO A MAXIMUM OF 6 FT/SEC IN |
| | THE BRANCH SUCTION PIPING WHEN ONE OF A PAIR IS |
| | BLOCKED. |
| | THE CALCULATIONS ARE BASED ON A THE TWO SPEED PENTAIR |
| | SUPERFLO 2HP POOL PUMP AND THE PLANS SPECIFY A 2.5 HP |
| | PUMP. THE 2.5 HP SUPERFLO PUMP APPEARS TO BE A SINGLE |
| | SPEED MODEL BECAUSE A LOW SPEED PUMP CURVE IS NOT SHOWN |
| | ON THE CHART FOR IT. PLEASE CORRECT. |
| | |
| | 3) SUBMIT TWO SETS OF TDH CALCULATIONS, WATER VELOCITY |
| | CALCULATIONS AND TURNOVER RATE CALCULATIONS. CITY |
| | AMENDMENTS 107.2.1.3, FBC R4101.6.3 AND R4101.20 |
| | THE SIMPLIFIED TDH CALCULATION HAS OTHER LOSSES LISTED |

| | CAN NOT BE JUSTIFIED THE TDH IS 22. THE TDH YOU SHOW AS |
| | 41.5 FEET WHICH INCLUDES THE 19.5 FEET. ON THE PUMP |
| | CHART USING 41.5 FEET, THE FLOW RATE FOR THE 2 HP AT |
| | HIGH SPEED IS 88 GPM. AT 88 GPM FLOW RATE, TO COMPLY |
| | WITH WATER VELOCITY REQUIREMENTS THE BRANCH PIPING FOR |
| | THE MAIN DRAIN SHOULD BE 2.5 " TO COMPLY WITH 6 FT/SEC |
| | AND THE REST OF THE SUCTION PIPING SHOULD BE 2.5" TO |
| | COMPLY WITH 8 FT/SEC. THE SUPPLY PIPING SHOULD BE 2" TO |

| | PLANS SPECIFY A 2.5 HP POOL PUMP WITH A FLOW RATE OF |
| | 130 GPM AT 60 FEET TDH. THE VELOCITY IN THE SUCTION AND |
| | RETURN LINES SHOWN ON THE PLANS DO NOT COMPLY WITH THE |
| | MAXIMUM VELOCITIES ALLOWED BY FBC R4101.6.3 & |
| | ANSI/APSP-7 2006 SECTION 4.4. PLEASE CORRECT. |
