New water bore Ellenbrook

Today we drilled a successful water bore in Ellenbrook.

If you are thinking of getting a submersible water bore in the Ellenbrook or surrounding suburbs it is good to know what is happening in your area.

When we drilled this Ellenbrook bore it was 13 metres to water. So we drilled the bore 27 metres deep to maximise flow and guarentee longevity of the supply of water. The 1.1 kw submersible pump we installed easily delivered 95 litres per minute. We will join some of the existing reticulation stations together to accommodate this flow which is nearly triple that being delivered by mains scheme water. Our driller marked the water quality eight of ten for clarity.

The picture here is of the bore just after drilling and casing. It was air developed and gravel packed and is now waiting for our team to install the submersible pump. After pump installation the casing will be cut down and everything will be finished off underground with the lawn replaced. In a few weeks time you won’t be able to have seen we have even been there. The submersible pump will operate silently at the bottom of the bore casing delivering fresh, free ground water to this Elelnbrook garden.

If we can help you with a water bore in the Ellenbrook area call us on 92460111 and we would be happy to help you.

New submersible water bore 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.

 

New submersible motor and pump Doubleview

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.

Perth reticulation controller needs replacing?

Whether your retic timer is faulty or simply old and you are not able to program your required Perth watering days, we can help.

We replace reticulation timers in all Perth suburbs. We will fix your retic controller whether connected to mains water or a bore. If it is a plug-in style we send out our service man. If it needs hard-wiring to the mains power our electrician will attend.

Some retic controllers, like the Holman model pictured, look like they may be hard wired but this one actually had a plug pack transformer plugged into a power point in the roof.

We have compatible models to replace all brands of retic controllers including Holman, Rain Bird, Rainmaster, Hunter, Toro, Orbit, Richdel and Irritrol Rain Dial. We typically carry 6 and 9 station models in our mobile stock but we can get any size if required.

You can reach us on 9246 0111.

What size is my submersible bore pump?

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.

How to replace a submersible bore pump

Our team was called out to winch up a submersible water bore pump. We carry purpose built portable winches to easily pull up submersible pumps even in restricted access locations. This allows us to quickly replace or repair submersible pumps in any Perth water bores.

New water bore Ballajura

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.
