New submersible water bore Marangaroo

Drilling a new water bore in Marangaroo

Drilling a new submersible garden bore today in Marangaroo.

The depth to water (static water table) was quite deep at 42 metres, because the house was high up on a hill. We drilled to 54  metres in total. This gives 12 metres of water in the bore casing.

We will be installing a 1.5 kw (2hp) submersible pump which at this depth will deliver about 80 litres a minute. This will be double what the customer currently gets from mains water supply.

We will connect the bore to the existing reticulation sprinkler systems. We will join several stations together to come on at the same time to use the extra flow.

This Marangaroo bore was drilled in a day and mainly drilled through compacted sand. This was a messy job due to the drilling muds flowing backwards on a forward sloping block. Fortunately we are licensed to use the street’s high pressure fire hydrant and will use this water to wash down and clean up.

If you have any questions about a water bore in Marangaroo or surrounding suburbs Girrawheen, Koondoola, Alexander Heights, Landsdale and Darch call one of the guys on 9246 0111.

Drilling a water bore when building

If you are building a new house and thinking of having a new submersible water bore installed then we would normally do it in two stages.

Stage 1 – Drill, case and air develop the bore hole itself. As long as access for a drilling rig is not going to be restricted. This can be done just after the slab is placed or after the house is built.

This Perth customer knew access was doing to be restricted by limestone perimeter walls he was building so we drilled the bore hole when it was just a vacant lot. The bore casing left protruding above ground so it was obvious and protected from damage.

Stage 2 – After the house is completed and power connected we will return and install the submersible pump and motor. The bore casing will be cut off below ground and everything is connected.

If we can help you with a new submersible water bore at your new home please call one of the team on 9246 0111.

New submersible motor and pump Doubleview

Customer’s submersible pump and 3 phase motor

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.

What size is my submersible bore pump?

Leave a comment

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” ) We can answer any questions on your submersible bore on 9246 0111

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.

We repair modern submersible bores in all Perth suburbs.

How to replace a submersible bore pump

Leave a comment

Our team was called out to winch up a submersible water bore pump. They phoned on 9246 0111.

If your submersible water bore is not working we can winch up the pump and work out what needs repairing.

We carry purpose built portable winches to easily pull up modern submersible pumps even in restricted access locations. This allows us to quickly replace or repair submersible pumps in Perth water bores. You can see on this video part of the process of winching a submersible bore pump.

If we can help you with your bore problem phone Troy on 9246 0111 or visit our main website on http://www.virginbores.com.au.

Water bore problem Ballajura
Stuffed water bore Ballajura

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.

Why is my old Perth bore running out of water?

Leave a comment

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.  We can help on 9246 0111.

This can be a a problem with the reticulation system or with the pump.

Slotted PVC bore casing

Commonly it is an issue with 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.

If your old Perth water bore is running out of water call us on 9246 0111 and we will talk through the problem or book a service online

Water bore faulty Perth

Leave a comment

The sprinkler bans in Perth end at the end of August. We encourage you to only start using your Perth sprinklers when the garden needs it.

Perth bore owners have been out testing their water bores for the first time this spring. Some are faulty!

Electrical fault water bore

We are hearing similar stories like  “I’m starting my bore and the circuit breaker is tripping or fuse is blowing, what should I do?”. We would send our specialist bore electrician Dave who has been doing this for years and is expert and experienced with water 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.

New bore Wilson

Leave a comment

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.

Failed reticulation controller South Perth

Leave a comment

We had a call today from a customer in South Perth who reported her submersible bore was not working. She thought her Rain Master reticulation controller was OK because the screen still had a display.

Fix Retic controller
Rain Master Reticulation controller

We took out the 9 volt back up battery and the display disappeared. This simple home test showed there was either no mains power to the reticulation controller or its internal 24 volt transformer had failed. The reticulation controller needs a 24 volt output to switch the relay, that in turn starts the 240 volt single phase bore or 440 volt DOL starter in the case of a 3 phase pumps.

A bit of an investigation by our servicemen at the South Perth call out revealed that in this case the controller transformer HAD failed. We replaced the controller and there were smiles all round as the bore fired up and the sprinkler came on.
