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.
Most submersible bores in Perth have either a 1.1 kilowatt ( one and a half horsepower), 1.5 KW ( 2 HP ) or 2.2 KW ( 3 HP ) motor connected to a matching pump ( “wet-end” )
If the motor is a single phase then ordinarily it will have a start box mounted near the electrical meter box. This often has the kilowatts or horsepower marked on the front. These pictures show the common Sumoto pump start box where the kilowatt selection has been indicated in black markers. This one is 1.1 kilowatt.
For a three phase motor the only reliable way to determine the motor size is to pull up the motor and pump.

It was a busy day in Ballajura today. We got called to a couple of bore electrical problems which we sorted quite quickly. We couldn’t immediately help the last call though.
The gentleman had a submersible bore that was of dubious construction. Not only was the borehole itself drawing sand, something which incidentally does not happen if the correct screens and gravel packing is used, but also the submersible pump was stuck irretrievably down the bore hole. The submersible pump had been installed down the bore without a stainless steel draw wire. The owner had erected a tripod and attempted to retrieve the pump by hauling up the poly pipe on a block and tackle. Unfortunately the poly pipe had snapped some metres down the bore hole and the poly pipe and submersible pump were now completely stuck.
Next week we will be drilling a new water bore for him. We’ll be sure to do everything to best practice standards to avoid problems like this in the future. We suspect this original bore had been a DIY or at best done by a backyard operator. Make sure if you are having a bore drilled in Ballajura or surrounds you use a licensed driller and preferably one who is a member of the ADIA.

Some Perth bore owners are telling us their very old water bores are running out of water or that it runs for a minute or two then it runs out. This can be a a problem with the reticulation system or pump.
Commonly it is the yield of the bore itself and the pump is pumping water out faster than it is flowing in to the bore casing. Many people think the bore is not deep enough. At times the water table does drop & it is a depth related issue. More often the stainless steel bore screen or slotted PVC bore casing has become blocked. Sometimes the ground around the bore has reduced the water it will “allow” to flow through it. We would try air-developing, a process where large volumes of compressed air are pumped down the bore. We can also chemically clean and restore the bore with a combination of special cleaning compounds, surfactants and clay dispersants.

The Perth metro sprinkler bans have ended for 2014.
Perth bore owners have been out testing their water bores for the first time this spring. Some are faulty!
We are hearing similar stories. “I’m starting my bore and the circuit breaker is tripping or fuse is blowing, what should I do?”. We would send a bore electrician ( experienced in pumps and 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 visit our website on www.virginbores.com.au
Today we attended a house in Wilson. Wilson is a suburb near Riverton and Shelley on the Canning River.
The couple had lived in the house for 12 years and had a shallow old well style bore with a centrifugal pump in one concrete liner. They told us that on average they had spent $400 a year on “bandaid” fixes to the old bore which appeared to be an original DYI attempt. The centrifugal pump constantly lost prime and the water flow from the bore had been marginal. The couple have decided to bite the bullet and invest in a new trouble free submersible style water bore
Next week we will be drilling an 18 metre bore hole specifically designed for the ground conditions of Wilson. Wilson’s proximity to the river means our bore design must pay due regard to avoiding potential saline intrusion. We will install a submersible stainless steel pump that will have the same or greater flow than the existing pump so we can connect it straight into the customers existing reticulation sprinkler system with little modification. The bore will continue to be run from their existing retic controller.
The drilling sand from the new bore will be used to fill the old well.

People often get confused about what is a submersible pump. A picture tells
a thousand words.
Most Perth garden bores use a 1.1 kilowatt (1.5 horsepower), 1.5kw (2 hp) or
2.2kw (3 hp) submersible motor connected to a matching pump or more
correctly a matching “wet-end”. Where the confusion comes in is generally
people refer to the two units combined as a pump. Here our bore service man
has assembled a single phase motor to a 12 stage pump (wet-end ). The motor
is the bottom part furthest from his hand. The wet end is the part he is
gripping whilst he tightens the fitting where the rising 40mm poly pipe
mainline will be connected to deliver the water to the surface. Note the
black rubberized bore cable is connected to the blue lead connected to the
motor. This delivers the 240v power down the borehole to the motor. The
stainless wire is used to support the weight of everything down the bore
