Centrifugal Bore Pump Troubleshooting Guide

Centrifugal Bore Pump
Centrifugal Bore Pump

The following diagnostic guide applies when your centrifugal pump motor is running but water problems exist.

For any bore pump problems call us on 9246 0111 seven days a week for telephone advice or to book a service  Perth metro-wide. You can also visit our main website here.

(If pump is not starting at all then an electrical problem exists not covered in this guide. Call to book  a visit from one of our water bore / pump specialist electricians who have all the necessary tools for diagnosis or repair of pump electrical problems. More info covered here .)

Pump runs but no water?

  • Priming –  suction pipe not completely filled with water.
  • The check valve has failed
  • Discharge head too much – depth to water beyond pump range.
  • Suction lift too high.  Suction pipe may be too small or long, causing excessive friction loss.
  • The Impeller is blocked.
  • Suction pipe/screen/strainer completely blocked.
  • Pump motor running in reverse (check direction).
  • Air pocket in suction line.
  • Air leaks in suction line and/or shaft seal, gland packing.
  • Discharge line closed off, solenoid valve not opening or gate valve closed.

Poor flow?

  • Priming – casing and suction pipe not completely filled with liquid.
  • Discharge head higher than anticipated.  Check friction loss in piping.
  • Suction lift too high.  Suction pipe may be too small or long and causing excessive friction loss.
  • Impeller partially plugged.
  • Suction pipe/screen /strainer partially blocked.
  • Pump motor running in reverse (check direction).
  • Air pocket in suction line.
  • Air leaks in suction line and/or shaft seal, gland packing.
  • Foot valve too small.
  • Suction pipe not into the  water enough after draw-down.
  • Mechanical faults such as the Impeller damaged, gland-packing of shaft seal damaged or wear rings worn.

Water pumps OK then stops?

  • Leak in suction line.

Bore Automation Old Well

Bore automation Bull Creek
Manual gate valve feeding front station from bore

Today we are visiting a client in Bull Creek about automating his old well.

At the moment he turns on the old well manually from the DOL starter near the metre box. He then turns on two manual gate valves near the old well to send water to the front and back of his Bull Creek home.

We will send our specialist bore election to fully automate the system. He will install a new reticulation controller to interface with the bore. He will also run cables to the gate valves and we will replace with automatic 24 volt solenoid valves turned on and off by the reticulation controller.

We are expert at the automation of water bores. For more information check out our website HERE or call Troy on 9246 011

Water bore Meadow Springs

Recently we drilled a relatively shallow 16 metre water bore in Meadow Springs, south of Perth. Meadow Springs is a suburb of Mandurah, immediately northeast of central Mandurah.

Water bore coastal
New water bore Meadow Springs

The bores drilled in the Meadow Springs area are relatively shallow as there are some salt concerns further down. This bore was drilled through mainly limestone and sand using a trailer mounted rotary mud drilling rig. This is an excellent drilling rig to use when there is not much space and it is perfect for bores up to 40 metres in most Perth suburbs.

This Meadow Springs bore has a 1.1 kw stainless steel submersible pump that was connected to the client’s existing reticulation system.

We have drilled many water bores in the Meadow Springs and Mandurah area. Call us on 9246 0111 or to research your submersible water bore in the Mandurah area check out our main website

 

Leak Detection

Do you think you might have a leak in your reticulation, sprinkler system or anywhere else in your home? There is a simple test you can do yourself or call us on 9246 0111

Detecting a water leak
Checking the reading on your meter

Make sure you turn off all taps inside and outside the home and check there are no visible leaks. Make sure the dishwasher, washing machine, evaporative air conditioner and garden reticulation controller are not in use. Also make sure your toilet cistern is not filling after a recent flush.
Then go to your water meter and record the black and red numbers on your water meter (write down or photograph). Wait 30 minutes, making sure no water is being used and record the reading again. If it has changed you probably have a leak.
Clues that the leak may be in the garden area are wet patches or very green localized patches in your lawn. Of course if your reticulation system is fed from a bore this cannot be a cause. If your reticulation system is fed from mains water there should be a separate gate valve, often near the water meter, that can be used to isolate the retic as a potential leak.
Our reticulation mobile service team are leak detection experts and can locate and fix the leak in the garden. If the leak is inside the home there is a list of recommended Waterwise plumbers on the Water Corporation website.
If you have a leak or any issue with your reticulation system in Perth call Troy on 9246 0111 or read more on our website HERE

New reticulation system Noranda

 

If you would like a modern submersible water bore or a new reticulation system in the Noranda area call 9246 0111.

We drilled a new submersible garden water bore here last week at this house in Noranda, now we have installed a new reticulation system. With the extra flow from the bore versus mains scheme water, we were able to run pop up sprinklers for the lawn on one station and separate micro sprays for the garden beds on another. The half sprinklers that face the house backing onto the curb are prone to car tyre damage. So we installed come concrete surrounds to this line of sprinklers and those on the edge of the driveway to protect this new Noranda reticulation system.

New retic & bore Noranda

With the installation of a modern submersible water bore, the client is now able to use their sprinkler system three days a week instead of only two days allowed from mains water. This Noranda front garden is about to have a new lawn laid. They will be able to apply for a new lawn exemption and water the new lawn more often details here

While we were there, we popped our head over the side fence and took a look at the neighbor’s garden. We drilled new submersible water bore at the property last year and their garden looked great. We are very happy to get referrals from happy customers.

Can I use my water bore during Perth sprinkler bans?

 

Winter sprinkler bans are in place across Perth, Mandurah and parts of the South-West and Great Southern from June 1 until August 30 each year. Many people are not aware they are not allowed to use their reticulation during winter.

Turn off retic controller
Turn off retic controller

Perth has had winter sprinkler bans since 2010 and saving about  4.5 billion litres of scheme water each year.

What does this mean for Perth bore owners? Bore owners are allowed to flush irrigation systems once a week on their rostered watering days, either before 9am or after 6pm, for about 2 minutes per station during winter. They can also be run during the ban period for the purposes of installation, testing and repair. Hand watering is permitted during the ban and customers can apply for an exemption for new lawns.

You can get more information at the Water Corporation website HERE or if you have any questions about using your water bore in winter in Perth call 9246 0111. On this Water Corp link there is an interactive map that lets you know if your property is included.

It is important to check your water bore and reticulation during winter and if you have any issues call us and we will be happy to help.

What is my reticulation controller battery for?

 

Why does it matter that my reticulation controller battery has gone flat? The answer is that it really matters if you have a water bore. Call us on 9246 0111.

Perth Reticulation controller
Pro 469 Reticulation controller

 

What does a retic timer need a battery for anyway? There is a lot of misunderstanding about what a retic controller’s 9 volt battery does. Retic controllers have batteries to preserve the memory of that has been programmed in the event of a mains power fail.

The battery is normally only 9 volts and does not have the power to operate solenoid valves or pump start relays. Solenoid valves and most other irrigation devices operate on 24 volts. Most retic controllers are 240 volt mains powered with a transformer that steps down to 24 volt to operate the individual irrigation devices. It may seem like a minor inconvenience if you have a flat 9 volt battery in your controller as at first glance one would think it is not a big issue if you lose mains power and the controller has to be reprogrammed.

9 volt battery

BUT it can have nasty consequences if the controller operates a bore.

If mains power is lost to quite a few brands of reticulation controllers and there is no back up battery then when mains power is restored the controller resets all programming to factory default which is often 10 minutes per station per day. This may then turn the bore on to stations that don’t exist and the pump runs with nowhere for the water to go. This can damage the pump or pipe work of the bore.

This season we attended 3 bores that had been affected like this from Ocean Reef alone. All after a power fail. These bores, incidentally should have had the unused stations ‘looped out’ to safeguard against this. Remember it is wise to change your disposable 9 volt battery at least once a year. Some newer model controllers have rechargeable batteries. You can test both types by simply turning mains power off and checking whether the display to the retic controller is still working and whether customer program’s have been retained when mains power is turned back on.

Happy reticulation customer Carine

Ray from Carine was grateful for the work done on his retic by our reticulation repair team. He had phoned us on 9246 0111.

It was great he bothered to say thanks. Our specialist electrician tested circuits and found issues with solenoids which were replaced. He also tested the submersible motor. Our pump electricians have done thousands of jobs like this one all over Perth.
If you have issues with your solenoids or bore pump call Troy on 9246 0111 or check out our website

Good review Virgin Bores

New bore Wilson

Our Virgin Bores team have just finished installing a new submersible water bore in Wilson. This one we drilled to 19 metres at a newly completed house.

We backed the drilling rig truck up to the small perimeter wall and were able to drill “over” the slim high wall. The new bore is just behind the Virgin Bores sign on the other side of the wall. Note the small pile of sand resulting from drilling a 100mm diameter borehole to a depth of 19 metres. Water bearing ground was encountered at 5 metres.

Solenoid valves Wilson

Ready for retic in Wilson
New bore ready for retic in Wilson

This is pretty standard for Wilson. We installed a 1.5 horsepower (1.1 kilowatt) stainless steel submersible pump and Italian Sumoto motor. Included in this clients bore package was a 6 station Rainmaster reticulation controller. We then installed 4 solenoid valves in the ground and automated them. The 4 solenoid valves are pictured here adjacent to the actual borehead. The borehead was then covered over by a small green bore box and buried under the sand. The solenoid valves will be covered by valve covers for access if needed. Our bore electrician wired in the controller to auto start the bore pump and operate the solenoid valves.

Now a very easy job for the client to finish the reticulation sprinkler system. If we can help you with a bore or retic work in Wilson or surrounds please call us on 9246 0111 or visit Virgin Bores here
