Cleaning Shallow Well Jet To remove debris from venturi or nozzle, proceed as follows: 1. Disassemble pump per instructions on Page 8. 2. Turn venturi counterclockwise and remove it. The nozzle is now exposed. Remove it using a 5/8" hex socket wrench with extension. Turn counterclockwise. If socket wrench is not available, insert an ice pick or similar pointed tool carefully into the nozzle. This will dislodge debris. 3. Flush out the debris by running water through the nozzle in the same direction as the dislodging tool was inserted. 4. Reinstall nozzle and venturi. Do not ove.rtighten_ 5. Reassemble pump per instructions on Pages 8 and 9. 9 HELPFUL HINTS How to Handle a Gaseous Well In some areas well water contains gases which must be allowed to escape before the water is used. This can be done as shown in Figure 9. A good way of delivering gas-free water is to suspend a pipe, closed at the bottom and open at the top, surrounding the suction pipe. Since the gases rise in the well casing, the water sucked down through the pipe and into the suction pipe is free of gas, This type of wen must be vented to the outside of any enclosure. Gases rise to suflace pipes_eeve Not pipe to Scale 2_03_ valve sleeve cap Figure 9 lO TROUBLE Motor will not run Motor runs hot and overload kicks off Motor runs but no water is delivered (*Note: Check prime before looking for other z:auses. Unscrew priming plug and see if there is water in priming hole) Pump does not deliver water to full capacity (also check point 3 immediately above) Pump pumps water but does not shut off Pump cycles too frequently Air spurts from faucets Leaks at the metal clamp [J_WARNING] Release all pressure in system before working on clamp! TROUBLESHOOTING POSSIBLE CAUSES 1. Disconnect switch is off 2. Fuse is blown 3. Starting switch is defective 4, Wires at motor are loose, disconnected, or wired incorrectly *5. Motor is wired incorrectly 6. Pressure switch contacts are dirty "1. Motor is wired incorrectly 2. Voltage is too low 3. Pump cycles too frequently "1. Pump in a new installation did not pick up prime through: a. Improper priming b. Air leaks c. Leaking foot valve *2. Pump has lost its prime through: a. Air leaks b. Water level below suction of pump 3. Jet or impeller is plugged 4. Check valve or foot valve is stuck in closed position 5. Pipes are frozen 6. Foot valve and/or strainer are buried in sand or mud 1. Water level in well is lower than estimated 2. Steel piping (if used) is corroded or limed, causing excess friction 3, Offset piping is too small in size 1. Pressure switch is out of adjustment or contacts are "frozen" 2. Faucets have been leftopen 3. Jet or impeller is clogged 4. Motor is wired incorrectly 5. Water level in well is lower than estimated 1. Pipes leak 2. Faucets or valves are open 3. Foot valve leaks 4. Pressure switch is out of adjustment 5. Air charge too low in Captive Air_ Tank 1. Pump is picking up prime 2. Leak in suction side of pump 3. Well is gaseous 4. Intermittent over-pumping of well 1. Loose clamps or "O" ring not sealed ]] GUIDE REMEDIES 1. Be sure switch is on 2. Replace fuse 3. Replace starting switch 4. Refer to instructions on wiring 5. Refer to instructions on wiring 6. Clean by sliding piece of plain paper between contacts 1, Refer to instructions on wiring 2. Check with power company. Install heavier wiring ifwire size istoo small. See wiringinstructions 3. See section below on too frequent cycling 1. In new installation: a. Re-prime according to instructions b. Check all connections on suction line and jet c. Replace foot valve 2. In installation already in use: a. Check all connections on suction line, jet and shaft seal b. Lower suction line into water and re-prime. If receding water level in a shallow well operation exceeds suction lift, a deep well pump is needed 3. Clean jet or impeller according to instructions 4. Replace check valve or foot valve 5. Thaw pipes. Bury pipes below frost line. Heat pit or pump house 6. Raise foot valve and/or strainer above well bottom 1. A deep well jet pump may be needed (over 20 ft. to water 2. Replace with Plastic Pipe where possible, otherwise with new steel pipe 3. Use larger offset piping 1. Adjust or replace pressure switch 2. Close faucets 3. Clean jet or impeller 4. Refer to instructions on wiring 5. Check possibility of using a deep well jet pump 1. Check connections, replace pipe fittings 2. Close faucets or valves 3. Replace foot valve 4. Adjust or replace pressure switch 5. Disconnect electrical power and open faucets until all pressure is relieved. Using automobile tire pressure gauge, check air pressure in tank at the valve stem located at top of tank. If less than 40 pounds, pump air into tank from outside source, until 40 pounds pressure is reached. Check air valve for leaks, using soapy solution, and replace core if necessary 1. As soon as pump picks up prime, all air will be ejected 2. Check suction piping, make sure joints are not sucking a...
