4. Rapid cycling
5. Inadequate wiring
1. Contact an electrician
2. Replace or take to motor replare shop
3. Provide a shaded, well-ventilated area for pump
4. See pump starts and stops too often section below
5. Rewire

NOTE:
check to
make sure pump is
primed before looking
for other causes.
Unscrew priming plug
and see if water is in
priming hole.
1. Water level below pump intake
2. Discharge not vented while priming
3. Leak in suction piping
4. Well screen or inlet clogged
5. Clogged nozzle

5. Clear obstruction from nozzle
6. Replace air volume control
7. Clean or replace as needed
8. Continue priming, pausing every 5 minutes to cool pump body. Refill pump
as needed
9. Select applicable pump and/or jet assembly
10. Replace as needed
11. Install baffle on pump intake to prevent gas from entering system
12. Inspect and replace
13. Purchase a jet matched to your system
14. Increase horsepower of pump
15. Increase suction plumbing diameter or decrease pipe friction
16. Contact an electrician
Pump starts and
stops too ofen
1. Water-logged tank (Conventional Tank)
2. Air volume control tubing kinked or clogged
3. Air volume control tubing connected to wrong
opening on pump
4. Incorrect tank pressure (pre-charged tank)
5. Ruptured disphragm/bladder (pre-charged tank)
6. Leak in house piping
7. Foot valve or check valve stuck open
8. Motor overload tripping
9. Improperly adjusted or damage pressure switch

2. Clean or replace as needed
3. Move to correct pump opening
4. Add or release air as needed
5. Replace tank
6. Locate and repair leak
7. Remove and replace
8. See overload trips section

PRÉCAUTIONS ÉLECTRIQUES - Avant tout entretien ou réparation de pompe, TOUJOURS couper le courant au disjoncteur, puis débrancher la pompe.
S'assurer de ne PAS rester debout dans l'eau, et porter des chaussures à semelles de protection isolées. En cas d'inondation, vérifier auprès de la
société locale d'électricité ou d'un électricien agréé qualifié pour couper le service électrique avant le retrait de la pompe.
