| | DENIED BY PLUMBING |
| | |
| | 1) SHOW COMPLIANCE WITH 2010 FBC ENERGY CONSERVATION |
| | SECTION 403.9.4 (3) AND HOUSE BILL 849 WHICH REQUIRE |
| | FILTRATION POOL PUMPS 1 HP AND GREATER TO HAVE A |
| | DEFAULT CIRCULATION SPEED THAT RESULTS IN A FLOW RATE |
| | THAT WILL NOT TURN THE POOL OVER IN LESS THAN SIX HOURS |
| | OR 36 GPM WHICHEVER IS GREATER WITH A HIGHER SPEED |
| | OVERRIDE CAPABILITY FOR A TEMPORARY PERIOD NOT TO |
| | EXCEED ONE NORMAL CYCLE OR 24 HOURS, WHICHEVER IS LESS. |
| | THE PLANS SPECIFY A 3.68 HR TURNOVER RATE AT 60 GPM. |
| | |
| | 2) SUBMIT THE MANUFACTURER'S SPECIFICATIONS WITH PUMP |
| | CURVES FOR THE SPA AND POOL FILTRATION PUMP. THE |
| | MAXIMUM FLOW RATES FOR TWO SPEED OR VARIABLE SPEED |
| | PUMPS ARE REQUIRED TO BE USED TO DETERMINE THE WATER |
| | VELOCITY IN THE POOL PIPING. BASED ON THE INFORMATION |
| | ON PENTAIR'S WEBSITE, THE MAXIMUM FLOW RATE FOR THE 3 |
| | HP PENTAIR VS-3050 IS 145 GPM AT 56 FT TDH. AT THIS |
| | RATE THE WATER VELOCITY IN THE 3" BRANCH PIPING IS 6.58 |
| | FT/SEC WHICH EXCEEDS THE 6 FT/SEC WHEN ONE OF THE PAIR |
| | IS BLOCKED THAT IS ALLOWED BY ANSI / APSP- 7 2006 |
| | SECTION 4.4. THE MAXIMUM FLOW RATE FOR THE 2 HP PENTAIR |
| | WHISPERFLO IS 140 GPM AT 39 FT TDH, WHICH RELATES TO A |
| | WATER VELOCITY OF 6.36 FT/SEC IN THE 3" PIPE. THIS |
| | EXCEEDS THE 6 FT/SEC ALLOWED IN THE BRANCH PIPING. |
| | PLEASE CORRECT. NOTE: ONLY THE BRANCH PIPING AT THE |
| | MAIN DRAINS DOES NOT COMPLY, THE REST OF THE SUCTION |
| | PIPING WILL COMPLY. IF CHANNEL DRAINS ARE USED IN LIEU |
| | OF THE TWO MAIN DRAINS, THERE IS NO BRANCH PIPING |
| | REQUIREMENT. |
