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.

  • 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.

Bore Automation Old Well

Bore automation Bull Creek
Manual gate valve feeding front station from bore

Today we are visiting a client in Bull Creek about automating his old well.

At the moment he turns on the old well manually from the DOL starter near the metre box. He then turns on two manual gate valves near the old well to send water to the front and back of his Bull Creek home.

We will send our specialist bore election to fully automate the system. He will install a new reticulation controller to interface with the bore. He will also run cables to the gate valves and we will replace with automatic 24 volt solenoid valves turned on and off by the reticulation controller.

We are expert at the automation of water bores. For more information check out our website HERE or call Troy on 9246 011

coastal water bores

Water bore Meadow Springs

Recently we drilled a relatively shallow 16 metre water bore in Meadow Springs, south of Perth. Meadow Springs is a suburb of Mandurah, immediately northeast of central Mandurah.

Water bore coastal
New water bore Meadow Springs

The bores drilled in the Meadow Springs area are relatively shallow as there are some salt concerns further down. This bore was drilled through mainly limestone and sand using a trailer mounted rotary mud drilling rig. This is an excellent drilling rig to use when there is not much space and it is perfect for bores up to 40 metres in most Perth suburbs.

This Meadow Springs bore has a 1.1 kw stainless steel submersible pump that was connected to the client’s existing reticulation system.

We have drilled many water bores in the Meadow Springs and Mandurah area. Call us on 9246 0111 or to research your submersible water bore in the Mandurah area check out our main website

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.

Portable winch used to pull up submersible pumps
Portable winch used to pull up submersible pumps

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 start capacitor problem

We often get water bore repair calls where the problem turns out to be the start capacitor. Call on 9246 0111. 

Water bore start box and capacitor
Start capacitor and start box
Start capacitor in start box
Start capacitor in start box

In a single phase submersible bore pump the start capacitor is ordinarily in the 240 volt start box. Three phase submersible pumps do not have start capacitors. In some centrifugal pumps the capacitor can be mounted externally on the pump motor housing. It is surprising how often a faulty capacitor is missed as the cause of a bore pump problem particularly when tests are carried out by someone who is not specifically experienced in bore pump service work. Even trained general electricians can misdiagnose this simple problem.

Often a capacitor problem can spotted visually as it will commonly swell or rupture. A start capacitor should be perfectly cylindrical. Sometimes though a faulty capacitor can only be diagnosed by the serviceman actually testing it when disconnected. As the start box is mains powered it does need a licensed electrician or certified electrical worker to test and replace the start capacitor. Our specialist bore electrician Dave is expert at this.

One of our clients from Baldivis sent us these pics of inside his submersible water bore start box.

This is a single phase start box and is a particularly dramatic example of a blown start capacitor.

Bore electrician, Electrical Problems

Electrical bore problem Beechboro

Leave a comment

Our specialist bore electrician recently fixed a circuit breaker that was tripping in Beechboro. Call 9246 0111.

Dave, our electrician, tested the single phase submersible pump and all the electrical tests were OK but were marginal on this Beechboro water bore.

There was an old metal start-box which was rusted out and dangerous. He replaced and rewired the start box with a new 1.5 kw rated box with matching start capacitor. Dave replaced some dangerous connections at the bore head and retested everything. Given the apparent age of the submersible pump it will likely need replacing in the next few years. We have recommended that at that time the down hole electrical cable and stainless steel draw wire is also replaced.

Dave is an excellent bore electrician and ask him why one of our customers called him a “little treasure”

We have a wealth of experiencing servicing bores and pumps throughout Perth. Give us a call on 9246 0111 or visit HERE  for more information or if we can help you.

Ray from Carine was grateful for the work done on his retic by our reticulation repair team. He had phoned us on 9246 0111.

It was great he bothered to say thanks. Our specialist electrician tested circuits and found issues with solenoids which were replaced. He also tested the submersible motor. Our pump electricians have done thousands of jobs like this one all over Perth.
If you have issues with your solenoids or bore pump call Troy on 9246 0111 or check out our website

New Water Bores

New water bore Nedlands

New water bore Nedlands
New water bore Nedlands

Our new installation arm Virgin Bores are drilling a new Water Bore in Nedlands tomorrow. The depth to water here in Florence Road is about 36 metres so we will drill to a total depth of 38 metres for plenty of water.
The garden bore will be equipped with a of 1.1 kilowatt submersible pump. Pretty standard for most Water Bores in Nedlands and Dalkeith. This will deliver about 90 litres per minute to the surface. Perfect for a typical Nedlands garden retic system. The small white vertical stake indicates where we will be drilling the bore. Alongside the brick wall is the 100mm PVC borecasing that will be installed permanently in the borehole. The bottom 6 metres of the casing is finely slotted to allow the water in. Around this we pack a fine layer of screened drillers gravel to act a s a permanent filter.
If you’re interested in a new bore or bore and retic repairs in Nedlands, Claremont or Dalkeith please call us on 92460111.

New submersible motor and pump Doubleview

Leave a comment
Customer's submersible pump and 3 phase motor
Customer’s submersible pump and 3 phase motor

A Doubleview customer sent us this picture of his submersible pump and 3 phase motor. He and his electrician had pulled it out of his very old 32 metre submersible bore hole. They had disassembled it and electrically tested the motor.

The motor needed replacing. We attended and replaced the motor and while we were at it a new submersible pump. We replaced all down hole electrical cable which we heat shrunk to the new motor lead. We also replaced his old frayed stainless steel draw-wire but reused the existing 40 mm poly rising mainline that delivers the water. The poly pipe was all good even after several decades of service. At the same time we dosed the bore with 20 litres of chlorine to help kill the iron oxide bacteria that was evident.

Finished off with a new bore box at the bore head, reconnected and all set to go. Most Doubleview water bores are in the 30 to 60 metre deep range as a consequence of Doubleview’s elevation. If you have any questions call our team on 9246 0111.
