PORTABLE ELECTRICAL EQUIPMENT TO APPROVED PERMANENTLY INSTALLED RECEPTACLES.
WORK EXEMPT FROM PERMIT
• PLUMBING:• 1. THE STOPPING OF LEAKS IN DRAINS, WATER, SOIL, WASTE OR VENT PIPE; PROVIDED IF ANY CONCEALED TRAP,

WORKING TOGETHER
• NEED TO WORK WITH BOTH THE HEALTH DEPARTMENT AND BUILDING DEPARTMENT. THE BUILDING OFFICIAL SHOULD BE NOTIFIED WHEN WELL PERMITS ARE APPLIED FOR.
INSPECTIONS
TRENCHING
• THE LOCAL BUILDING INSPECTOR SHOULD BE INSPECTING THE TRENCHES.
• IRC SECTION P2603.5 REQUIRES WATER SERVICE PIPE TO BE INSTALLED NOT LESS THAN 6 INCHES BELOW THE FROST LINE. THAT WOULD BE 48 INCHES TO THE TOP OF THE PIPE IN CT.
• IRC SECTION P2603.4 REQUIRES THE SLEEVE THROUGH A FOUNDATION WALL TO BE TWO PIPE SIZES GREATER THAN THE PIPE PASSING THROUGH THE WALL.
TRENCHING (CONT.)
• IRC SECTION 2604.1 – BOTTOM OF THE TRENCH SHALL FORM THE BED OF THE PIPE AND SHALL PROVIDE A SOLID AND CONTINUOUS SUPPORT.
• NO ROCKS IN CONTACT WITH THE PIPING.• ROCKY SOILS SHALL BE OVER-EXCAVATED BY
TWO PIPE DIAMTERES AND BROUGH UPWITH SUITABLE MATERIAL (SAND, FINEGRAVEL, COMPACTED EARTH, ETC.)
• IRC SECTION P2604.3 – BACKFILLING SHALL BE FREE FROM DISCARDED CONSTRUCTION MATERIAL AND DEBRIS.
• IRC SECTION P2606.1 – SEALING OF ANNULAR SPACES – BOTH SIDES OF THE FOUNDATION WALL SHALL BE SEALED
WATER SUPPLY SYSTEMS
IRC SECTION 2903.3 MINIMUM PRESSURE – THE STATIC WATER PRESSURE AT THE BUILDING ENTRANCE SHALL NOT BE LESS THAN 40 PSI
•PRESSURES IN EXCESS OF 80 PSI REQUIRE THE INSTALLATION OF A RPD
P2903.7 WATER-SERVICE MAINS SHALL NOT BE LESS THAN ¾ INCH DIAMETER.
ELECTRICAL REQUIREMENTS
VOLTAGE DROP
NEC 210.19(A) INFORMATION NOTE #4 CONDUCTORS FOR BRANCH CIRCUITS SHOULD BE SIZED TO PREVENT A VOLTAGE DROP 3% AND THE MAXIMUM VOLTAGE DROP ON BOTH FEEDERS AND BRANCH CIRCUITS DOES NOT EXCEED 5%.
(THE LENGTH OF THE CONDUCTORS SHALL BE FROM THE WELL PUMP ALL THE WAY BACK TO THE OCPD)
THE CONDUCTORS FROM THE PUMP CONTROLER SHALL ALSO BE THE SAME SIZE AS FROM THE WELL PUMP TO CONTROLER.
BE AWARE OF THE TYPE OF CB, EACH TYPE AND MANUFACTURE WILL HAVE INFORMATION ON THE MAXIMUM SIZE WIRE PERMITTED TO BE INSTALLED UNDER THE TERMINAL.
GROUNDING ELECTRODES
NEC 250.52(A)(1) – METAL UNDERGROUND WATER PIPE.
A METAL UNDERGROUND WATER PIPE IN DIRECT CONTACT WITH THE EARTH FOR 10 FT. OR MORE (INCLUDING ANY METAL WELL CASING BONDED TO THE PIPE SHALL BE BONDED
NEC 250.112(M) – METAL WELL CASINGSWHERE A SUBMERSIBLE PUMP IS USED IN A METAL WELL CASING, THE WELL CASING SHALL BE CONNECTED TO THE PUMP CIRCUIT EQUIPMENT GROUNDING CONDUCTOR
THE INSTALLATION INSTRUCTIONS FOR SUBMERSIBLE PUMPS ALSO REQUIRE GROUNDING TO THE WELL CASING AS PART OF THEIR LISTING.
WIRE SIZING
WHAT INFORMATION DOES THE BUILDING OFFICIAL NEED?
• HP OF THE WELL PUMP
• VOLTAGE OF THE WELL PUMP
• DEPTH THE WELL PUMP IS SET
• LENGTH OF WIRE FROM THE PUMP TO THE OCPD
• WIRING TYPE• SHALL BE LISTED FOR WET LOCATIONS (NEC
310.10(C))
• DIRECT-BURIAL CONDUCTORS SHALL BE EITHER UFTYPE OR USE TYPE, LISTED FOR DIRECT-BURIAL
• OTHER TYPES OF WIRING SHALL BE RUN IN A LISTED RACEWAY (WELL PIPE IS NOT A LISTED RACEWAY)
PROPER INSTALLATION?
UF Cable used from well casing into the building
Wiring method is protected from physical damage
PROPER INSTALLATION?
Wiring is type THW, which shall be run within a listed raceway, (well pipe is not a listed raceway)
NEC 300.5(G) Raceway seal. The end shall be sealed with an identified compound so as to prevent the entrance of moisture and gases
Water service pipe shall conform to NSF 61 with a working pressure of not less than 160 psi @ 73ºF (IRC P2905.4)
PROPER INSTALLATION?
WHAT IF A GENERATOR IS PRESENT?
IF THE PUMP IS BEING LOWERED AND/OR A LARGE PUMP IS BEING INSTALLED AND THE STRUCTURE HAS AN AUTOMATIC TRANSFER SWITCH ELECTRICAL LOAD CALCULATIONS WILL NEED TO BE PERFORMED PER NEC 702.4(B) FOR THE GENERATOR AND SUBMITTED WITH THE APPLICATION.
ISSUANCE OF A CERTIFICATE OF OCCUPANCY
IRC SECTION P2901.1 – DWELLING UNITS SHALL BE SUPPLIED WITH POTABLE WATER IN THE AMOUNTS ANDPRESSURES SPECIFIED IN THIS CHAPTER.
WHO DETERMINES WATER POTABILITY?SANITARIAN AND NOT THE BUILDING OFFICIAL
GEOTHERMAL WELLS
GROUND SOURCE HEAT PUMP SYSTEM LOOP PIPING
IRC M2105.1 - THE ASSEMBLED LOOP SYSTEM SHALL BE PRESSURE TESTED WITH WATER AT 100 PSI FOR 30MINUTES WITH NO OBSERVED LEAKS BEFORE CONNECTION (HEADER) TRENCHES ARE BACKFILLED. FLOWRATES AND PRESSURE DROPS SHALL BE COMPARED TO CALCULATED VALUES. IF ACTUAL FLOW RATE ORPRESSURE DROP FIGURES DIFFER FROM CALCULATED VALUES BY MORE THAN 10%, THE PROBLEM SHALL BEIDENTIFIED AND CORRECTED.
2018 STATE BUILDING CODE
2018 STATE BUILDING CODE
RESIDENTIAL SPRINKLERS MAY BECOME PART OF THE 2018 STATE BUILDING CODE, WHICH ISCURRENTLY BEING REVIEWED FOR ADOPTION IN THE FIRST HALF OF 2018.
HOW WILL THIS AFFECT YOU?
WATER SUPPLY
IRC P2904.5 WATER SUPPLY• 1 STORY DWELLINGS <2,000 SQ FT = 7
MINUTE WATER SUPPLY• ALL OTHERS REQUIRE 10 MINUTE WATER
SUPPLY• WHERE A WELL SYSTEM, A WATER SUPPLY
TANK SYSTEM OR A COMBINATION THEREOF SHALL BE PERMITTED TO MEET THE CAPACITY REQUIREMENTS
WHAT DOES THIS MEAN?• RESIDENTIAL SPRINKLER HEADS REQUIRE 8-31
GPM• MOST RESIDENTIAL SYSTEMS WILL HAVE
HEADS REQUIRING NO MORE THAN 22 GPM
WATER SUPPLY (CONT.)
• IF A ROOM HAS TWO OR MORE HEADS, THE DESIGN FLOW RATE SHALL BE BASED ON THE HIGHEST FLOW RATE FOR TWO HEADS
• ROOMS WITH ONE HEAD SHALL BE BASED ON THAT ONE HEAD
EXAMPLE CALC.(2 HEADS)(22 GPM EACH)(10 MINUTES) = 440
GALLONS REQUIRED CAPACITY.6” WELL CASING = 1.469 GALLONS PER FOOT.(440 GALLONS)/(1.469 GAL/FT) = 299.5 FT > 300
FTIF THE DIFFERENCE IN ELEVATION BETWEEN THE
STATIC WATER LEVEL AND THE PUMP IS < 300 FTA STORAGE TANK IS REQUIRED
WATER SUPPLY (CONT.)
THE LOCAL BUILDING OFFICIAL WILL NEED A COPY OF THE WELL COMPLETION REPORT ALONG WITHINFORMATION ON THE WELL PUMP AND THE DEPTH OF THE WELL PUMP.
FINAL POINTLET US ALL WORK TOGETHER
