How to Choose a Borehole Pump Installer

Picking the wrong person to install your borehole pump is one of the more expensive mistakes a Johannesburg homeowner can make. A submersible pump sitting at the bottom of a casing costs real money, and getting it back out for a remedial job costs more still. The problem is that the work sits at the intersection of plumbing, electrical, and groundwater disciplines — which means plenty of generalist contractors present themselves as qualified when they are not.

This guide gives you the specific questions to ask and the credentials to verify before you hand over any deposit.

Why pump installation is a specialist job

Installing a borehole pump is not the same as fitting a pressure pump to a tank. The work involves lowering a submersible unit down a narrow casing — sometimes 60 to 100 metres deep — connecting it to rising main, wiring it to a control panel with the correct motor protection, and setting up the surface components: pressure vessel, isolators, and where applicable, a VSD (variable-speed drive) to protect the motor from dry-run damage.

Get any of those elements wrong and you risk burning out a pump that may cost R15,000–R35,000 installed, or worse, losing it down the hole. The groundwater side also has legal implications — anyone working on a registered borehole is operating in a regulated environment under the National Water Act.

The one credential that matters most

The Department of Water and Sanitation requires that anyone who installs, alters, or repairs a water-use system linked to a groundwater source must be registered as a water-use contractor. The Groundwater Division of South Africa (GWD) maintains a list of registered drillers and associated contractors.

Before you engage anyone, ask for their DWS contractor registration number and check it. This is not bureaucratic box-ticking — it is the minimum threshold that separates contractors who understand the regulatory framework from those who do not. If an installer cannot produce a registration number, that is a clear signal to keep looking.

For the full picture on what a compliant borehole setup involves, the borehole drilling overview on this site explains the process from drilling through to commissioning.

Electrical competence is non-negotiable

A borehole pump motor is a high-current, single or three-phase electrical load, often running on a dedicated circuit. The installer must either be a registered electrician themselves or work directly alongside one who will sign off the installation with a Certificate of Compliance (CoC).

Ask specifically:

• Who will issue the electrical CoC?
• Is that person registered with the Department of Employment and Labour as an Electrical Contractor?
• Will the panel include motor-overload protection and a dry-run cut-off?

A pump wired without proper overload protection will burn out the moment the borehole yield drops — which it will, during Johannesburg’s dry months.

Questions to ask before signing anything

Beyond registration, a short conversation tells you a lot. Here is a practical list:

Question	What a good answer looks like
How many submersible pump installations have you done in the past year?	A specific number, ideally 20 or more
Can you provide two or three references from pump-only jobs (not full drills)?	Yes, with contact details they are happy for you to use
What make and model of pump do you recommend for my yield and depth, and why?	A reasoned answer tied to your specific water report
Who issues the electrical CoC?	Named electrician with registration number
What does your workmanship warranty cover, and for how long?	Typically 12 months on labour; parts are manufacturer-covered
Do you carry professional indemnity and public liability insurance?	Yes, with a policy number they can provide

Do not skip the references. A competent installer will not hesitate. One who hedges — “my clients prefer privacy” — is telling you something.

For a detailed guide on verifying the credentials yourself, the post on checking installer credentials walks through each step practically.

If you want to skip the cold-calling and compare installers who have already been screened for registration and insurance, compare 3 free quotes — vetted installers, no obligation.

What to look for in the quote itself

A professional quote should be itemised, not a single lump sum. You should be able to see:

• The pump make, model, and rated flow rate
• Cable size and length
• Rising main specification (diameter and material)
• Control panel specification
• Pressure vessel size
• Surface pipework and connections
• Labour and any access equipment
• What is explicitly excluded

If the quote does not separate the pump supply cost from the installation labour, ask for a breakdown. This matters because if you need to claim on a manufacturer’s warranty, you need to know exactly what was supplied. Our separate piece on borehole pump installation costs explains what each line item should typically run to, so you can sense-check figures before you accept.

Typical complete borehole pump systems — pump, cable, rising main, control panel, and surface connections — run R15,000–R35,000 installed as a rough guide, though figures outside that range are not unusual depending on depth, pump specification, and site complexity. Always confirm with at least two or three quotes.

The Consumer Goods and Services Ombud applies here

Most homeowners do not realise that borehole pump installation work on a residential property falls within the Consumer Protection Act, which means the Consumer Goods and Services Ombud (CGSO) can hear complaints if an installer fails to deliver what was contracted. Keep a paper trail: written quote, signed acceptance, written variations, photographs before and after commissioning.

If something goes wrong and the installer will not engage, the CGSO provides a no-cost dispute process. That is a meaningful safety net, but it only works if you have documentation. Verbal agreements are very hard to pursue.

Not sure which pump specification suits your borehole's yield and depth? Get matched with a registered installer who can assess your site and give you a written recommendation.

Red flags that should make you walk away

To summarise the warning signs in plain terms:

• No DWS contractor registration number when asked
• A quote delivered verbally or as a single total with no line items
• Pressure to pay a large deposit (more than 30–40% is unusual for established contractors)
• No mention of an electrical CoC
• Vague or no warranty terms
• Reluctance to provide references from completed pump installations

None of these individually is proof of incompetence, but more than one in combination is a strong signal to keep looking. Johannesburg has enough registered, experienced pump installers that you do not need to take a chance on someone who cannot answer basic questions about their own qualifications.
