Bore not working in South Perth

A resident of South Perth was concerned as their reticulation was not working and they contacted us on 9246 0111.

They reported that they could hear the typical “çlunk” sound  as the contactor engaged when they started the bore pump from their retic controller.

Our electrician found that the one horsepower Sumoto submersible motor was not fused. The motor windings appeared to be intact but there was a complete dead short to earth.

His recommendation was that we replace the submersible motor, wet-end and electrical cable down the bore hole for new. He disabled and taped up motor tails in the borehead junction box and all the other electrics tested OK.

So another member of the team returned and replaced the .75KW submersible motor, 15 metres of electrical and stainless and barrell union. All tested OK and another South Perth water bore was back up and running for the hot summer months ahead.

When there is a problem with a water bore it takes experience and skill to diagnose the problem and repair efficiently, quickly and economically for the Perth householder.

What is a submersible pump?

Assembling a submersible pump

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
