Pl ·_p; NIPPLE INSTALLATION During manhole installation, a one-half inch diameter threaded pipe nipple shall be installed through the manhole wall directly on top of one of the sewer pipes entering the manhole. The threaded end of the nipple shall extend no more than two inches on.the inside of the manhole. The total length of the nipple shall exceed the manhole wall thickness by no less than four inches. The pipe nipple shall be non-corrosive and resistant to chemicals common in domestic sewage. Special attention shall be given to providing a permanent, water-tight seal around the pipe nipple at the manhole wall. 'rhe pipe nipple shall be sealed with a threaded one-half inch cap. Every manhole need not have a pipe nipple, A few key manhcle locations should be sufficient to establish a groundwater profile for the test area. The Engineer shall assist the Contractor in selecting appropriate manholes for pipe nipple installation. 2. GROUND WATER ELEVATION Im.mediately before air testing, the groundwater level shall be determinedby removing the threaded cap(s) from the nipple(s) nearest the section to be tested, blowing air through the pipe nipple(s) to remove any obstructions, and then connecting clear plastic tube(s) to the pipe nipple(s). Each plastic tube shall be held vertically to allow groundwater to rise in it. After the water level in the tube has stopped rising, a measurement of the height in feet of water over the invert of the sewer pipe shall be taken. If the section to be tested is not immediately adjacent to an installed pipe nipple, the groundwater height shall be estimated based upon nearby height readings and the pipe's invert elevation. 3, AIR PRESSURE ADJUSTMENT The air pressure correction, which must be add.ed to the 3. 5 psig normal test starting pre.ssure, shall be calculated by dividing the average vertical height, in feet of groundwater above the invert of the sewer pipe to be tested, by 2 •. 3 l. The result gives the air pressure correction in pounds.per square inch to be added. (For example, if the average vertical height of groundwater above the pipe invert is 2. 8 feet, the-additional air pressure required would equal 2,8 divided by 2.31 or 1.2 psig. This would require a 111inimum starting pressure of 3.5 plus 1. 2 or 4. 7 .Psig. ) The allowable pressure drop and the timing are not affected and shall remain the same. 4 • MAXIMUM TEST PRESSURE In no case should the starting test pressure exceed 6. O psig. If the average vertical height of groundwater above the pipe invert is more than 5. a feet, the section so submerged may ba tested using 6.0 psig as the starting test pressure. The 6.0 psig limit is intended to further ensure workman safety and falls within the range of the pressure monitoring gauges normally used. 5. RESEALING OF PIPE NIPPLES After the groundwater height has been determined, each pipe nipple shall be recapped and sealed to prevent any future infiltration. APPROVED SCALI:: •. �Q�� ...... •.
