Plumbing Installation Certificate of Compliance (Water By-law Certificate) in Cape Town
If you are buying or selling a property within the City of Cape Town, a Water Installation Certificate of Compliance (Water By-law Certificate) is a legal requirement before the property can be transferred. In accordance with the City of Cape Town Water By-law, a valid certificate must be issued for every transfer to confirm that the property’s water installation complies with the applicable municipal regulations.
At Thermoelectrics, we provide professional Water Installation Certificate of Compliance inspections for residential and commercial properties across Cape Town. Our qualified inspectors conduct thorough assessments to ensure your property’s water installation meets the requirements of the City’s by-law, helping to avoid delays during the transfer process.
What Is a Water Installation Certificate?
A Water Installation Certificate confirms that the property’s potable water installation complies with the City of Cape Town’s Water By-law requirements. It is important to note that this certificate is not the same as a full plumbing certificate and does not cover every aspect of the plumbing system.
The certificate focuses specifically on municipal water compliance and is required each time ownership of a property changes within the City of Cape Town.
What We Inspect
During our inspection, we assess key components of the water installation, including:
- Visible water supply pipes and fittings
- Water leaks that result in the loss of potable water
- Geyser installations and required safety components
- Pressure control valves and vacuum breakers
- Cross-connections between potable and non-potable water systems
- Stormwater connections to ensure they do not discharge into the sewer system
- Other items required under the City of Cape Town Water By-law
If any non-compliant items are identified, we provide a detailed report and can arrange the necessary repairs before issuing the Water Installation Certificate of Compliance.
Water Installation Certificate vs Plumbing Certificate
Many people assume these certificates are the same, but they serve different purposes.
A Water Installation Certificate of Compliance:
- Is issued in accordance with the City of Cape Town Water By-law
- Applies specifically to property transfers within the City of Cape Town
- Covers the potable water installation only
- Identifies leaks that result in the loss of drinking water
- Includes checks on required water-related safety components
- Verifies that stormwater is not incorrectly connected to the sewer system
- Must be obtained every time the property is transferred
A Plumbing Certificate of Compliance, on the other hand:
- Covers the entire plumbing installation
- Includes wastewater and sewer systems
- Assesses waste traps, drainage systems, and sewer connections
- Identifies faults such as damaged sanitary fittings, leaking waste pipes, and defective plumbing components
- Ensures compliance with the applicable plumbing standards and regulations rather than only the municipal water by-law
Fast and Reliable Water By-law Inspections
Property transfers often operate under strict deadlines, and delays in obtaining a Water Installation Certificate can hold up the registration process. Thermoelectrics provides prompt inspections, professional reporting, and efficient remedial services to help ensure your property transfer proceeds without unnecessary complications.

My go to team from now on. My municipalty main supply in my dB desided to short to neutral and burn 22:00 on a Saturday evening, and the municipality breaker did not trip. It was fireworks inside my house, not a good sight or feeling. After phoning 10 different electrical companies stateing 24/7 on call, some even answering and saying they will only come the next day as it is late, Warwick had no hesitation to come through and assist. The house would have burned down if it was not for Warwick. He stayed the entire time to ensure the municipality shuts off the power to my house, worked on my dB till 03:00 in the morning to ensure we can power up safely again and wanted to still clean where he worked. Great service, great work ethics, great quality standards. Thanks again.Posted on Google Mandy Simpson11 May 2026Trustindex verifies that the original source of the review is Google.

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.
