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.
  • Leakage of air into pump casing.
  • Air pocket in suction line.
  • Suction lift too high.
  • Insufficient groundwater.

Not Enough Pressure?

  • Speed to low.
  • Air in water.
  • Wrong impeller diameter.
  • Mechanical fault – Wear rings worn. Impeller damaged. Shaft seal or gland-packing damaged.
  • Wrong direction of rotation.

Water pumps OK then stops but pump still running

  • Leak in suction line.
  • Leakage of air into pump casing.
  • Air pocket in suction line.
  • Suction lift too high.

Pump is noisy.

  • Hydraulic noise – cavitation,  too much suction head.
  • Mechanical Faults including  – pump and drive unit out of alignment ,rotating elements binding, shaft bent, bearings worn.

Pump leaks .

  • Gland Packing worn/loose. Shaft seal damaged.
  • Packing incorrectly inserted or not properly run in.
  • Shaft scored.
  • Housing damaged.

Nedlands Water Bores

This week George and the team drilled a 38 metre modern submersible water bore in the leafy Perth suburb of Nedlands.

New water bore being drilled in Nedlands

It was drilled through sand and limestone and there was a good supply of groundwater from 24.5 metres onwards.

With no access to the front lawn this one was drilled in the parking area to the side of the drive. Nice clean up again guys!

Once the pump has been put down the bore hole, it will be connected to reticulation. A green bore box will be put over the top and paving will be all put back and everything tidied up.

If you are in the Nedlands area or surrounding areas of Claremont or Dalkeith and have been considering a water bore call us on 9246 0111.

Water bore North Beach

George and the drilling team did a great job getting the drilling rig positioned at this job in North Beach.

The team drilled a 30 metre modern submersible water bore for this North Beach customer and got a plentiful supply of crystal clear water.

Difficult access on a sloping driveway drilling into a small walled garden bed. Way to go George!

All was tidied up and just the 100 mm bore casing left sticking out of the ground and a small pile of drilling waste sand on the verge.

Next we will cut down the bore casing to under the surface level and install the submersible pump.

If you have been at home and been thinking about a water bore, now is a great time. Call us on 9246 0111.

Wanneroo Water Bore

Russell is one of our specialist drillers for shallower water bores in the greater Perth metropolitan area.

He and his team take a lot of pride in their work so they were pretty pleased with the ‘gusher’ they drilled in Wanneroo recently.

Water Bore in Wanneroo

Wanneroo is generally pretty shallow for a water bore and the bore pictured was 18 metres deep with the bore pump set at 10 metres.

The moment of truth is before even the pump is installed when compressed air is forced down the borehole to develop up and prove the supply.

If you live in Wanneroo and would like to save money and have the best garden in the street call us on 9246 0111.

Reconnect Water Bore after Renovations

If you have a submersible water bore and you are doing renovations, it is important to consider the water bore as part of your planning.

Old Fremantle Bore

We attended a job in North Fremantle that had an old submersible bore that was working before renovations but had not been reconnected.

Fremantle bore repairs
A bit of detective work and digging around this old bore in Fremantle uncovered what needed doing

We sent our electrician to test the motor and quote the on the cost of re-connection of the submersible water bore.

He found the motor tested OK but that it was an old installation with imperial sizes, no slack on the bore head cable and lots of limestone in ground and concrete around the house. It will be a challenging job to reconnect electrically.

Fremantle Water Bore

Fix bore Fremantle
The submersible bore was in a concrete pit filled with sand and barely visible.

There was a new  start box needed to even test the bore itself was OK electrically as original start box was missing.

Once the bore is back up and running this one is to be wired just for manual operation as the owner intends  to continue using it just manually from a hose. Later if it is connected to automatic reticulation we can install a reticulation controller.

If you are renovating and have a water bore, call us for advice on 9246 0111 or go to our website HERE

We fix bores and retic in all Perth suburbs

We are in Fremantle and surrounds on a daily basis fixing bores and repairing reticulation sprinkler systems. You can also call us for any Perth suburb

Drill new bore Baldivis

Virgin Water Bores recently drilled a new bore in Baldivis.

The last man onsite is normally our Jack who connects the bore to the existing reticulation system and tests that everything is OK.

He then makes sure the stations are balanced. This means he often doubles up existing retic stations so two come on at once to accommodate the higher flow from a bore. He then tidies up and makes sure everything is working perfectly before handing over the job to the customer.

The existing retic controller now turns on the bore for a supply of free groundwater, programmed to come on an extra day a week as allowed. This bore is carefully concealed under the paved driveway.

For a quote on a new submersible garden bore please call us on 9246 0111 or enquire online.

Information on Winter Sprinkler Bans

Tomorrow (June 1 2018)  you need to turn off your reticulation and water bore for the winter sprinkler bans. This involves households, businesses and councils in Perth, Mandurah and parts of the South-West and Great Southern.

Anyone who uses sprinklers from June to August risks a $100 fine.

Retic ban in Perth in Winter
Winter sprinkler Swutch-off in Perth from June 1 to August 31

Bore water users are allowed to flush sprinkler systems once a week on their normal rostered watering days, either before 9am or after 6pm, for 2 minutes per station to maintenance test their bore. Hand watering is permitted when needed. If you have just installed a new lawn you can apply for a new lawn exemption HERE

Any questions about the Winter Sprinkler Switch-Off can be answered at this Water Corporation website

Water Minister Dave Kelly reminded us that the switch-off saved about five billion litres of scheme water in winter 2017, enough water to fill up Optus Stadium five times.

Winter is a great time to consider a domestic water bore so you and your garden are ready for summer. Waiting times are shorter. Call us on 9246 0111 or go to our website HERE.

 

Bore Pump Repair Nedlands

Today we replaced a two wire bore pump motor for a customer in Nedlands after they phoned  our service line 9246 0111. Their modern submersible water bore was not working.

Our specialist bore electrician inspected the junction box at the top of the submersible bore which contained the two wire pump motor in Nedlands and diagnosed a ruptured internal capacitor.

Repair or Install Water Bore Perth’s Coastal Suburbs

Pictured is the bore start box for a submersible water bore at a home in the coastal Perth suburb of Trigg.

bore start box for Trigg water bore
Trigg water bore start box

There was an existing reticulation system at this home in Trigg when new water bore was drilled. The reticulation system was disconnected from mains water near the water metre. The retic controller was on a back wall of the house and was wired to send a 24V start signal to this bore start box.

The bore start box is located next to the electrical meter box next to the front door.

We have been in the water boring business for nearly 20 years and can install and repair your water bore. We have the experience and the knowledge to work out what is wrong with your water bore if it needs repair.
