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?

Bore pump and retic repairs Como

We have just replaced a faulty submersible pump motor for a customer in Como. It was a submersible bore that had been enclosed or drilled inside an old style concrete well liner. After nearly 20 years in the business we are experts in the area.

As well as replacing the faulty pump motor, we also replaced the wet end (pump). the down bore hole cable and the single phase Lowara bore start box. The start box was installed on an existing post next to the well. All electrical work was done by  our licensed and bore experienced electrician.

Bore not starting Booragoon 

We had installed a bore for Bob in Booragoon a few years ago.

He rang to say the bore was not working. We sent out our specialist bore electrician Dave. The submersible pump motor tested ok and he noted that there was no 24 volt to relay from controller.

He found that there was a red multicore running along the pavers from below the reticulation controller to below the bore start box. The joint connection at the bottom of the start box was faulty so he remade it.

All working again on front 2 stations. There was no cover on station 3,4,5 and 6, it was cut off due to construction. He fixed.

We have drilled and repaired many bores in the Booragoon area and surrounding suburbs of Mount Pleasant, Myaree and Melville. If you have a problem with your Booragoon bore call Troy on 9246 0111 or if you submersible pump is not working find help  HERE

Water bores in Two Rocks

We have vast experience in drilling and servicing water bores in the Two Rocks area and surrounds over the last two decades.

We have drilled dozens of bores stretching from Yanchep and Two Rocks across to Seatrees Estate and  Breakwater Estate. Bores in the area range from some shallow ones right near the coast at Yanchep and Two Rocks typically around 18 metres and up to 60 metres further inland near Seatrees Estate and Breakwater Estate.

In the smaller residential blocks in Two Rocks we normally install 1.1kw submersible pumps perfect for normal home gardens. In the 5 acre blocks over at Seatrees and Breakwater we would normally instal a 1.5 or 2.2 kw pump to give closer to 150 litres per minute.

All new drilling and installations are handled by our new Bore team at Virgin Bores.

For bore service and repair call Troy on 0408 454 130 or if you live in the Two Rocks area and you would like to discuss a submersible water bore look 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.
