| | DENIED BY PLUMBING |
| | |
| | 1) THE PLANS SPECIFY A 1.5 HP JANDY STEALTH SERIES |
| | VARIABLE SPEED PUMP WHICH REQUIRES THE MAXIMUM FLOW |
| | RATE OF THE PUMP TO BE USED IN CALCULATIONS. THE PIPING |
| | SCHEMATIC SHOWS 2.5" PIPE ON THE SPA SUCTION LINES AND |
| | THE MAIN DRAIN DETAIL SPECIFIES 2.5 " BRANCH PIPING |
| | BETWEEN THE TWO MAIN DRAINS. PLEASE CLARIFY. THE SPA |
| | MAIN DRAIN BRANCH PIPING BETWEEN THE TWO MAIN DRAINS IS |
| | LIMITED TO A MAXIMUM OF 6 FEET PER SECOND WHEN ONE OF |
| | THE PAIR IS BLOCKED PER ANSI/APSP-7. MAXIMUM OUTLET |
| | SIZE ON THE MANUFACTURED MAIN DRAIN SUMPS IS TYPICALLY |
| | 2-1/2" AND IS CONSIDERED PART OF THE MAIN DRAIN BRANCH |
| | PIPING PER DEFINITION 3.5 OF ANSI/APSP-7 2006. |
| | THEREFORE, THE MAXIMUM BRANCH PIPING SIZE IS 2-1/2". |
| | UNLESS TDH CALCULATIONS ARE SUBMITTED THE MAXIMUM FLOW |
| | RATE OF THE PUMP WILL BE USED TO DETERMINE THE WATER |
| | VELOCITY. PLEASE SHOW HOW THE POOL PIPING WILL COMPLY |
| | WITH ANSI/APSP-7 SECTION 4.4 AND FBC R4101.6.3. |
| | |
| | 2) THE SIZE OF THE BRANCH PIPING AT THE TWO SIDE DRAINS |
| | FOR THE SHEER DESCENT FEATURE IS NOT SPECIFIED. PROVIDE |
| | THE PUMP SPECS. WITH THE PUMP CURVE AND TDH |
| | CALCULATIONS TO SHOW COMPLIANCE FOR THIS SYSTEM AS |
| | WELL. |
| | |
| | 3) SUBMIT 2 COPIES OF THE SPECIFICATIONS FOR THE POOL |
| | PUMP INCLUDING THE PUMP CURVE. |
| | |
| | 4) SUBMIT 2 COPIES OF TOTAL DYNAMIC HEAD (TDH) |
| | CALCULATIONS FOR THE SYSTEM OR DESIGN THE SYSTEM FOR |
| | THE MAXIMUM FLOW RATE OF THE PUMP. |
