TROUBLESHOOTING
PUMPS installed on a well or drop/suction pipe, water or other liquid source,
may be a well, tank, spring, cistern barrel, etc. Where maximum lift, pumping
level and distance to water does not exceed 25-30 feet unless using deep well model. (9 meters)
These pumps may also be used as a hand held bilge pump, barrel/drum pump or for initial priming a jet or centrifugal pump.
INSTALL pump on well pipe, or suction/drop pipe. Teflon tape or a good quality thread, sealant should be used on all threads. Make up threads on pump hand tight or enough to prevent leaks.
PRIME pump by water into the discharge and pumping handle until
all air is eliminated an pump is primed. If handle continues to pump easy with little or no resistance (pumps air) and does not prime, the problem is a hole or leak (bad connection) in the suction pipe, above the water level. Be sure suction pipe is submerged. If handle pumps hard (back-pressure) and delivers little or no volume, the problem is the suction or intake is obstructed (well point or screen plugged/stopped-up) or lift exceeds 25-30 ft.
A common problem with small diameter driven or screened wells, is a plugged well
point or screen. For example, let us say we have a 2 in. driven well 30 ft. in depth with what appears to be a static water level of 10 ft. This would indicate we have plenty of water. But if we have a plugged point/screen, this condition may prevent the water reaching true static level which we will say in this example, is 18 ft. A good way to check this is to pour water in the well pipe to the surface. If it stands full or goes down very slowly, the well point is plugged (stopped up or sealed off) If the water goes down
rapidly or you cannot fill the pipe, the well point is open and should produce
water. To correct this condition, (plugged well point/screen) pull the pipe
and replace point/screen or acid treat the well. If you are unfamiliar with this
procedure, contact us for details.
Note: On many applications it is desirable to use a foot valve with an intake strainer on the drop pipe. This creates positive prime and prevents undesirable material from entering the suction pipe. Performance and ease of prime will be improved if the internal check valve assembly in the pump is removed when using a foot valve. When pumps are to be used in this manner, they may be ordered without the internal check valve.
