Areas We Service

What is a Water Installation Certificate?

A Water Installation Certificate is an official document confirming that a property’s water installation complies with the City of Cape Town Water By-law at the time of inspection. It certifies that the water system has been inspected by a qualified plumber and meets the municipal requirements for property transfers.


Is a Water Installation Certificate required when selling a property in Cape Town?

Yes. In the City of Cape Town, a Water Installation Certificate is required when ownership of a property is transferred. The seller is responsible for providing this certificate to the conveyancing attorney before the transfer can be finalised, unless otherwise agreed in the sale contract.


Who is responsible for obtaining the Water Installation Certificate?

In most cases, the seller is responsible for arranging and paying for the Water Installation Certificate before the property transfer takes place. However, the Offer to Purchase may contain different arrangements, so it is important to review the sale agreement carefully.


What is inspected during a Water Installation Certificate inspection?

A qualified plumber will inspect various aspects of the property’s water installation to ensure compliance with the City of Cape Town’s Water By-law. This typically includes checking:

  • Visible water leaks
  • Geyser installation
  • Pressure control valves
  • Isolation valves
  • Water meter operation
  • Stormwater connections
  • Cross-connections between potable and non-potable water
  • Plumbing fittings and pipework
  • Compliance of the hot and cold water systems

The inspection helps ensure the property is not wasting water and complies with municipal regulations.


Why is a Water Installation Certificate important?

A Water Installation Certificate helps protect both buyers and sellers by confirming that the property’s plumbing installation complies with municipal requirements. It also assists in identifying hidden leaks, faulty plumbing components, and other issues that could result in water wastage, increased municipal bills, or expensive repairs after the property has been sold.


What are the most common reasons a property fails a Water Installation Certificate inspection?

Some of the most common defects include:

  • Leaking taps or pipes
  • Faulty toilet cisterns
  • Incorrectly installed geysers
  • Missing or defective pressure control valves
  • Stormwater connected to the sewer system
  • Missing vacuum breakers
  • Cross-connections between potable and alternative water supplies
  • Visible plumbing leaks
  • Non-compliant plumbing alterations

Most defects can be repaired before the certificate is issued.


What happens if my property fails the inspection?

If non-compliant items are identified, the inspector will provide a report explaining the defects that require attention. Once the necessary plumbing repairs have been completed, the installation can be re-inspected and the Water Installation Certificate issued once the property complies with the applicable requirements.


Can Thermoelectrics carry out the plumbing repairs?

Yes. If your property does not comply during the inspection, Thermoelectrics can arrange for qualified plumbing professionals to complete the required repairs. Once the defects have been rectified, the property can be re-inspected and the Water Installation Certificate issued.


How long does a Water Installation Certificate inspection take?

The inspection time depends on the size and complexity of the property. Most residential inspections take between 30 minutes and one hour. Larger homes or commercial properties may require additional time.


How long is a Water Installation Certificate valid?

A Water Installation Certificate confirms that the property’s water installation complied with the City of Cape Town Water By-law at the time of the inspection. There is no fixed legal expiry period, but a new certificate is generally required each time ownership of the property is transferred.


Does every property in Cape Town need a Water Installation Certificate?

Yes. Most residential properties being transferred within the City of Cape Town require a Water Installation Certificate before transfer can be completed. This requirement forms part of the City’s efforts to reduce water wastage and ensure compliance with municipal plumbing regulations.


Does a Water Installation Certificate guarantee there are no future plumbing problems?

No. A Water Installation Certificate confirms that the visible water installation complied with the applicable municipal requirements at the time of the inspection. Plumbing systems can develop leaks or faults over time, so regular maintenance is still recommended.


Can a leaking tap cause the property to fail?

Yes. Even seemingly minor plumbing defects, such as leaking taps, leaking toilets, or visible pipe leaks, may need to be repaired before a Water Installation Certificate can be issued. These issues contribute to unnecessary water wastage and are considered during the inspection.


Are geysers inspected during the Water Installation Certificate inspection?

Yes. The geyser installation is an important part of the inspection. The inspector will assess whether the geyser installation complies with the applicable plumbing requirements, including components such as pressure control valves, drip trays where required, overflow pipework, and visible plumbing connections.
