FAQ

What People Are asking

I have low pressure, is my well drying up?

Answer: Not necessarily. Low pressure may be caused by several smaller problems with your equipment. Contact us and one of our experts will save you time and money by quickly diagnosing the problem.


I don't have any water. What should I check before calling for service?

Answer: Your first step should be to check your power supply, such as your circuit breaker or fuses. Secondly, check your main water supply valve and make sure its open. The water pump system in your home can sometimes be complex. If you are unsure of what the exact cause of the problem is, call us to prevent further difficulty.


I just had my pump replaced. Does it come with any warranty?

Answer: The pumps installed by LWT come with a one-year, manufacturer warranty. Our company offers an additional four-year warranty, which will then give you a total of five-years


What type of casing/well screens will be used?

Answer: The type of formation that contains the water will have a significant influence on this. Soft, sandy formations need to be screened to allow the water in but stop the sand from getting into the borehole. Allowing sand to enter the pump will cause premature failure of not only the pump, but also the entire installation.


What will the diameter of the borehole be?

Answer: A diameter of 152 mm (6 inches) complete is viewed as the standard for a domestic borehole. We will then insert a 125mm class 9 slotted pipe for the lining. Larger diameter holes are considerably more costly and are the preserve of large irrigation, water supply and mine dewatering systems.


What will the depth of the borehole be?

Answer: If you have obtained professional help in establishing the approximate depth at which a water bearing formation can be expected, you will need to communicate this to prospective drilling companies. Deep boreholes (+150m) can require larger machines that are not available to some contractors, or will not fit into your property.


Will the driller do borehole development?  How will the driller improve water yield if necessary?

Answer: Once the hole has been drilled to the final depth, it will need to be thoroughly flushed to remove all loose debris. In addition, the water bearing formation will  need to be worked in a way that allows easy passage for the water to enter the borehole. This process is called borehole development. If the driller does not understand the meaning of borehole development, get another driller.


Will the driller be able to continue drilling through intersecting clay, unconsolidated sand or hard rock?

Answer: Drilling through soft and hard formations requires certain skills and  equipment. In addition, there could be additional costs incurred by the  driller. The BWA Standard Form of Contract takes these into account by stating, upfront, what additional charges are applicable if these difficult formations are encountered.


You only have to pay if the driller drills to the depth specified in the contract.

Answer: The driller can not guarantee that water will be found, generally it is accepted that the driller will get paid for work done and unless the driller finds water at a lesser depth and it is agreed, in writing, to stop drilling, then the work done must be paid for even if no water is found.


How do I know that the driller is not over charging for the drilling of the hole?

Answer: The BWA recommends that the driller  provide samples of material from each metre drilled. These samples are  very useful to geohydrologists and to contractors who have years of experience. You can take a number of photos (a mobile phone camera is sufficient) of the sample mounds and save them as part of the records  pertaining to the installation.


Is the provision of a driller's log of  the borehole included in the price?

Answer: A driller's log gives details of the  construction of the borehole such as total depth, diameter(s) casing types, size(s) and length(s) and types of screens installed at specified  depths. Should the driller provide a turnkey service whereby, in addition  to the drilling, the pump is selected, installed, and commissioned then and  electrical clearance certificate, a yield test certificate, and a form  containing pump details, and commissioning data must be provided. These documents are a definite advantage when the time comes to sell your property.
