PRIMING THE PUMP

Priming refers to the pump expelling all air in the system and
beginning to move water from its source out into the system.
It does not refer only to pouring water into the pump (although
pouring water in is usually the first step).
1. Make sure suction and discharge valves and any hoses on
discharge side of pump are open.
2. Remove priming plug. Fill pump and suction pipe with
water (Figure 10). NEVER run pump dry. Running pump
without water in it will damage seals and can melt impeller
and diffuser. Be sure discharge (valve, pistol grip hose
nozzle, etc.) is open whenever pump is running.
• If a priming tee and plug have been provided for a long
horizontal run, be sure to fill suction pipe through this
tee and replace plug. Remember to tape the plug.
• Replacing the existing priming plug with one that has a
pressure gauge and reducer bushing mounted in it will
make troubleshooting pump performance easier.
3. Start pump. Water should be produced in 10 minutes or
less. The time depends on the well's depth to water and
the length of horizontal run. If no water is produced within
10 mins., stop pump, release all pressure, remove priming
plug, refill, and try again.
WARNING Hazardous pressure and risk of ex plo sion and
scalding. If pump is run con ti nu ously at no flow (that is, with
discharge shut off or without priming), water may boil in pump
and piping system. Under steam pressure, pipes may rupture,
blow off of fittings or blow out of pump ports and scald anyone
near.
