Troubleshooting Chart

PROBLEM	POSSIBLE			CAUSES
Motor will not run.	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.	Pressure		switch	contacts		are dirty.

REMEDIES

1.Be sure switch is on.

2.Replace fuse.

3.Replace starting switch.

4.Refer to instructions on wiring.

. Check and tighten all wiring.

5.Clean by sliding piece of plain paper between contacts.

Motor runs hot and overload kicks off.

Motor runs but no water is delivered.

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.

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 orimpeller is plugged.

4.Check valve or foot valve is stuck in closedposition.

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, caus'mg 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 left open.

3.Jet or impeller is clogged.

4.Water level in well is lower than estimated.

5.Motor is wired incorrectly.

I. Standard pressure tank is water- logged and has no air cushion.

2.Pipes leak.

3.Faucets or valves are open.

4.Foot valve leaks.

5.Pressure switch is out of adjustment.

6.Air charge too low in Captive Tank. Model 390.251483

and Model 390.251883 require 40 pounds for proper operation.

1.Pump is picking up prime.

2.Leak in suction side of pump.

3.Well is gaseous.

4.Intermittent over-pumping of well.

1.Refer to instructions on wiring.

2.Check with power company. Install heavier wiring if wire size is too small. See wiring instructions.

3.See secUon below on too frequent cycling.

1.In new installation:

a.Re-prime according to instructions.

b.Check all connections on suction line, air volume

conrail, and jet.

c.Replace foot valve.

2.In installation already in use:

a.Check all connections on suction line, air volume

control, 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 fm)t 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 steed pipe.

3.Use larger offset piping.

1.Adjust or replace pressure switch.

2.Close faucets.

3.Clean jet or impeller.

4.Check for possibility of using a deep well jet pump.

5.Refer to instructions on wiring..

1.Drain talxk to air volume control tapping. Check air

volume control for defects. Check for air leaks at any

connection.

2. Check cotmections.

3.Close faucets or valves.

4.Replace foot valve.

5.Adjust or replace pressure switch.

6.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. ff air pressure is lower, pump air into tank from

outside source, until proper air pressure is reached.

Check air valve for leaks, using soapy solution, and replace core if necessary.

1.As soon :ks pump picks up prime, all air will he ejected.

2. Check suction piping.

3.	Change	:installation	as described	in manual.
4.	Lower	foot valve	if possible, otherwise		restrict discharge
	side of	pump.

Leaks at the metal	1. Loose clamps or O-Ring
clamps,	not sealed.

_ WARNING I

Re{_a._ all pressurein system before working on clamp.

1. Release all system pressure

before working

on clamp.

2.Check that clamp is tight.

3.Tap arotmd clamp with hammer on a wooden block.

Retighten clamp screw.

4.Check ()-Ring for proper seating and/or dirt on

O-Ring or seat.
