Joondalup Bore Service and Repair

Our northern suburbs  bore repair team does a lot of work in Joondalup and surrounds. Today they attended a quite deep submersible bore just off Joondalup Drive.   Our 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.

Problem is no-one knows where the bore is located under the driveway. 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. 1300 734 300 or give Troy a call direct on 0408 454 130

We also drill new water bores in Joondalup. Call us for a quote or Visit our water bore drilling website here.

Bore Repairs Claremont

Just repaired a water bore in  Claremont. Found the submersible pump motor was not working. Our electrician certified it as fused and we helped the elderly client with her insurance claim. Her insurance policy covered pump motor fusion. it was quite deep for a Claremont bore and we winched the pump up over 30 metres. Call us anytime on Perh 1300 734  300 or give Troy a call direct on 0408454130. Our mobile service teams are ready to help.

Submersible Pump Motor Failed?

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

Bore Air-Development?

Water bore Air-development.
Water gushes out of a new bore as compressed air is pumped down the borehole.

Clients often ask what air-development of a water bore is. Ordinarily with a correctly constructed new water bore it is air-developed following drilling but before the installation of the submersible pump. This is particularly important in Perth’s typically sandy soils.  Air development is a process where compressed air is pumped down the

borehole both flushing out the drilling muds used to drill the bore and developing water flow from the aquifer. The accompanying diagram illustrates the results of development on a bore with a stainless steel screen. The principal is the same and equally important for those water bores constructed with slotted PVC screen. Slotted PVC screen is more common in Perth water bores.

Air-development is also used to clean out old , tired bores that have diminished water flows. It helps clear out years of silt etc and once again develops flow from the aquifer.

If your bore has reduced water flow call us for the solution on Perth 1300 734 300 or call Troy directly on 0408 454 130. Our mobile service teams operate Perth metro-wide.

Submersible Bore Pump Shaft Broken

Pump and motor uncoupled showing shaft.

Rare Perth service call yesterday to a submersible bore pump that was producing only about 25% of the water that it normally delivered.

Ruled out all the normal things like a hole in the poly rising main, pump wasn’t running backwards, none of the “normal” causes.???  Winched the submersible pump to the surface. The shaft joining the motor to the “wet-end” (pump) seemed OK but on uncoupling the submersible pump we noted inconsistencies. Found the shaft had sheared actually inside the pump leaving the first 4 of 12 impellors still turning. Quite an uncommon fault.

Further detective work found the unusual auto start device had been turning the pump on/off, on/off incessantly contributing to the failure. Replaced the pump and installed it all back down the borehole with the original motor. Tested and all good now!

Perth Water Bore Drillers

Drilling the new bore in Applecross

Last week our water bore drilling  bore arm, Virgin Bores, drilled another successful bore hole in Applecross.

First the drillers back their rig onto an accessible area of the front lawn, that is suitable for the customer. Depending on the depth of the hole, the actual bore drilling normally takes about half a day.

After drilling the bore is “air-developed” a process where compressed air is pumped down the borehole to clean the drilling muds and develop flow.

As you can see below in the pic of air developing a great result – lots of water and it looks crystal clear.

The submersible pump is normally installed the next day followed by the bore electrician and finally the reticulation connection if required.
