Old Submersible Bore Cable

Leave a comment

All submersible bores have electrical cable that goes down beneath the water table delivering mains power to the submersible pump (call us on 9246 0111)

It is important that the bore cable is sound and won’t allow water to get inside. Water ingress can lead to electrical failure of the motor or at best persistent tripping of the control equipment, circuit breaker or cause fuses to blow. Pictured is just part of this summer’s suspect or faulty electrical cable that has been replaced this year.

If you have a similar problem with your submersible bore our specialist water bore electricians have the experience, knowledge and equipment to diagnose the fault. Call us Perth metro wide 9246 0111 or visit our main website here

Submersible Pump Motor Failed?

Leave a comment

What are the causes of submersible bore pump motor failures?

The majority of  electrical failures of submersible pump motors in residential garden bore installations is as a result of the burning out of stator windings. Causes include, but are not limited to, high voltage surges/spikes and lightning strikes.

Other causes include-

  • The running of a pump against a “closed head” ( nowhere for the water to pump , closed valve, blocked outlets etc )  with limited water flowing past the submersible motor to aid in cooling, can cause failure of the thrust system. Dead-heading can also result in the “blowing” of the rising poly main line that delivers the water to the surface.
  • If a pump is run with not enough back pressure or head this can cause premature damage to upthrust bearings. It is important the pump is run on an accepted part of the “pump curve”. In a nutshell it must be running enough, but not too many, sprinklers.
  • Sand or abrasive matter in the bore  which can cause the shaft seal to wear ultimately causing submersible motor failure.
  • A failed check valve can cause back spinning of the pump impellors as the water flows back down the main line to equalize with static water level. This spins the pump at low RPM with insufficient lubrication. In deeper submersible bores this can, over time, cause failure.
  • constant stop/start, stop/start of the motor (machine-gunning) may lead to pump/motor shaft failure

Insurance Claim on Fused Submersible Pump

Leave a comment

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.

How do I know if my submersible pump motor is a “2 wire” or a “3 wire”?

Leave a comment

This terminology is used to describe the single phase motor that drives the submersible “wet-end” or pump. It is not used in reference to three phase submersible pumps. The difference between a “2 wire” and “3 wire” pump is based on the type of motor that is used. A “3 wire” single phase submersible pump motor requires a control box or start box that contains  a starting capacitor or start/run capacitor. This box is normally mounted near the power

source or buildings meter box. This has an on/off manual switch and motor running indicator. On installation an electrician puts a 24v relay in this to accept the signal from a reticulation controller if required, thereby automating the start box. Because of the method of starting, the motor requires three “hot” leads (plus a lead for the ground connection) to operate correctly. It is called a “3-wire” due to the three “hot” leads, though there are actually 4

individual wires when you count the earth (ground) wire. On the other hand a “2 wire” motor requires no control/start box because it does not use a starting capacitor.

Instead, a “2 wire” motor has a built-in electrical device that is used to start the motor. This only requires the pump to have 2 “hot” leads (plus earth), which is why it is called a “2 wire” pump.  But when counting the total number of wires coming to the surface we see a “2 wire” pump actually has 3 wires and a “3 wire” pump actually has 4  wires. Confused?  Fixing submersible bores and pumps is what we do every day.  Our experience is what sets us apart.

Water Bore Fusion Insurance Claims

Leave a comment

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”

    Submersible 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.

Pump stuck down bore?

Leave a comment

From time to time we are called to attend a water bore repair job where we find a submersible pump stuck down a bore hole. Most commonly it would be a 25 year old plus bore. But sometimes we see it in more modern bores. Occasionally it is the result of a lightning strike or lighning induction and the pump motor has blistered or swollen. More commonly it would be because tree roots have managed to get in to the bore hole through a breach in the casing or from the top. Sometimes it is that the stainless steel draw-wire has snapped. Occasionally the electrical cable has become entangled. Sometimes the borecasing itself is no longer truly perpendicular.There are a host of other reasons we have encountered.  More often than not we can recover the situation using our winch or other techniques.
