Centrifugal Bore Pump
Centrifugal Bore Pump

The following diagnostic guide applies when your centrifugal pump motor is running but water problems exist.

For any bore pump problems call us on 9246 0111 seven days a week for telephone advice or to book a service  Perth metro-wide. You can also visit our main website here.

(If pump is not starting at all then an electrical problem exists not covered in this guide. Call to book  a visit from one of our water bore / pump specialist electricians who have all the necessary tools for diagnosis or repair of pump electrical problems. More info covered here .)

Pump runs but no water?

  • Priming –  suction pipe not completely filled with water.
  • The check valve has failed
  • Discharge head too much – depth to water beyond pump range.
  • Suction lift too high.  Suction pipe may be too small or long, causing excessive friction loss.
  • The Impeller is blocked.
  • Suction pipe/screen/strainer completely blocked.
  • Pump motor running in reverse (check direction).
  • Air pocket in suction line.
  • Air leaks in suction line and/or shaft seal, gland packing.
  • Discharge line closed off, solenoid valve not opening or gate valve closed.

Poor flow?

  • Priming – casing and suction pipe not completely filled with liquid.
  • Discharge head higher than anticipated.  Check friction loss in piping.
  • Suction lift too high.  Suction pipe may be too small or long and causing excessive friction loss.
  • Impeller partially plugged.
  • Suction pipe/screen /strainer partially blocked.
  • Pump motor running in reverse (check direction).
  • Air pocket in suction line.
  • Air leaks in suction line and/or shaft seal, gland packing.
  • Foot valve too small.
  • Suction pipe not into the  water enough after draw-down.
  • Mechanical faults such as the Impeller damaged, gland-packing of shaft seal damaged or wear rings worn.

Water pumps OK then stops?

  • Leak in suction line.
  • Leakage of air into pump casing.
  • Air pocket in suction line.
  • Suction lift too high.
  • Insufficient groundwater.

Not Enough Pressure?

  • Speed to low.
  • Air in water.
  • Wrong impeller diameter.
  • Mechanical fault – Wear rings worn. Impeller damaged. Shaft seal or gland-packing damaged.
  • Wrong direction of rotation.

Water pumps OK then stops but pump still running

  • Leak in suction line.
  • Leakage of air into pump casing.
  • Air pocket in suction line.
  • Suction lift too high.

Pump is noisy.

  • Hydraulic noise – cavitation,  too much suction head.
  • Mechanical Faults including  – pump and drive unit out of alignment ,rotating elements binding, shaft bent, bearings worn.

Pump leaks .

  • Gland Packing worn/loose. Shaft seal damaged.
  • Packing incorrectly inserted or not properly run in.

Pulling up a submersible water bore.

If your modern submersible water bore is not working call us on 9246 0111 and we can talk through over the phone what the problem may be.

In some circumstances a submersible pump and motor will need to be pulled up to the surface by one of our water bore repair teams with a winch designed for the task.

The torpedo like submersible water bore pump is usually suspended at the bottom of the borehole by a stainless steel cable used to retrieve the pump. Also coming to the surface from the pump will be a flexible poly pipe that delivers the water and an electrical cable that powers the motor.

Our service teams connect the stainless draw wire to one of our purpose built portable electric winches and simply winch the pump to the surface. Simultaneously though it is important that we also manually gently pull up the electrical cable to prevent jamming and damage to the heat shrink joint.

If your water bore needs fixing call us on 9246 0111 and we will assess what we think is the problem over the phone and send the correct member of our team to fix your water bore. If you submersible pump needs to be pulled to the surface call 9246 0111 or get some detailed information on your submersible pump HERE

Water bore faulty Perth

The sprinkler bans in Perth end at the end of August. We encourage you to only start using your Perth sprinklers when the garden needs it.

Perth bore owners have been out testing their water bores for the first time this spring. Some are faulty!

Electrical fault water bore

We are hearing similar stories like  “I’m starting my bore and the circuit breaker is tripping or fuse is blowing, what should I do?”. We would send our specialist bore electrician Dave who has been doing this for years and is expert and experienced with water bores. He has special equipment to test the circuits & windings of the motor. We can do this without winching the pump up.

We remind our customers that if it is a fused bore pump motor it may be covered under household insurance. Also if the fault is storm related even damage from lightning induction that then this too may be subject to an insurance claim.

To have the matter attended to first by specialist bore repairers who can correctly diagnose the fault and possible cause call the team on 9246 0111 or book an online service and read more about faulty water bores HERE

Thanks Bore Electrician Kewdale and Pump Replacement Carine

It is great to hear from happy customers and hear good reviews. Thank you! 9246 0111

Thanks for sending our specialist bore electrician to Kewdale

Our experienced bore electrician Dave attended Russell’s Kewdale property, checked his system and supplied and fitted a new reticulation controller.

We also attended Philip’s Carine property where we replaced his .75 kw 2 wire submersible motor / pump and tested that everything was OK.

“Thank you for your teams excellent work just prior to Christmas. Having the bore operational again has been fantastic. Once again thank you and I am happy to recommend your services to anyone. Regards Phillip.”

If we can assist you with specialist bore electrical advise or pump replacement visit our website  HERE or phone Troy (ask him how his fishing is going) on 9246 0111

Joondalup Bore Service and Repair

Today our bore repair team attended a quite deep submersible bore just off Joondalup Drive after a call from a customer about a bore repair problem on 9246 0111.

Our specialist bore electrician tested the submersible pump motor from the surface at the control equipment and unfortunately it has tested both fused and down to earth.

Another problem is no-one knows where the bore is located under the driveway. It is important for the home-owner to note the location of the bore when drilling a new bore or if buying a home with a bore. It saves money and time locating it.

We know the depth to water at this location is about 50 metres so the bore will be over 60 metres total depth.  We will need to winch it to the surface and confirm the tests. If necessary we will then replace the 3 phase motor. If we can confirm the motor is fused then our electrician will write it up as fused which may well be an “insured event” under the homeowners insurance policy.

Pump electrical faults should always be tested and recorded by a licensed electrician. Call us any time if you have any problem with your water bore or reticulation system in Joondalup or surrounds on 9246 0111.

We also drill new water bores and repair water bores in Joondalup and the surrounding suburbs of  Edgewater, Heathridge and Connolly. Check us out on our website HERE

Insurance Claim on Fused Submersible Pump

If your submersible pump is fused it may be covered by your household insurance. Call us on 9246 0111.

We were happy to receive a handwritten note on Friday from a customer in Kardinya. We replaced his fused submersible pump motor and steered him in the right direction with his fusion insurance claim.

He said, “Thanks for fixing my submersible bore pump so promptly. I didn’t even know fusion might be covered under insurance“. Our electrician tested the motor and wrote it up as fusion.

Water Bore Fusion Insurance Claims

With the ending of Perth metro sprinkler bans for 2013  Perth bore owners are testing their water bores for the first time this season……and some aren’t working! We have had calls today all with similar stories. “I’m starting my bore and the circuit breaker is tripping ( or fuse is blowing), what do I do?”. First thing is we send a bore electrician ( one who is experienced in pumps and bores ) with special equipment to test the circuits and windings of the motor. With submersible motors this can be done without winching the pump up. Remember if it is a fused bore pump motor it may be covered under household insurance. Also if the fault can be traced back to one of winters electrical storms it may be related, even damage from lightning induction, and this too may be subject to an insurance claim. This is a very good reason to have the matter attended to first by specialist bore repairers who can correctly diagnose the fault and possible cause. 1300 734 300 will reach us 24/7

Water Bore Troubleshooting Guide – pump not starting – Perth

If the pump is not starting at all

  • check the fuse or circuitbreaker that should be in your meter box and labelled “bore” or “pump”
    Single phase bore circuit breaker

    Submersible pump start box
    Single phase pump start box
  • if it is 3 phase reset the  415-440v D.O.L ( Direct Online Starter)
  • if it is single phase there is most likely a separate 240v start box with a reset/over-ride switch. You should check that
  • does the 240 V start box have a burnt smell?

    3 phase DOL bore starter
  • if it is operated from a reticulation controller check that that has 240v power going to it. Just because the reticulation controller has a display does not mean it has 240v power. Remove the 9v back up battery and confirm there is still a display.
  • can you hear the 24 v relay clicking in or the contacter make a clunk sound when you start the retic contoller? Starting the reic controller sends a 24v signal to a relay or contactor which turns on the “mains” power to the bore pump.
  • if all the above seems OK and it is a submersible pump, perhaps the motor is starting and you can’t hear it but another related water delivery problem exists. Does your electricity meter speed up when you start the pump?
  •  if it is a centrifugal pump in a well have you checked the isolation switch?
  • have you recently had electrical work done to any of the wiring on your house?

Call  us on Perth 1300 734 300 if none of the above helped. We may be able to help further on the phone or we will send our mobile bore service teams to any Perth suburb. Further info is on our main website.
