The hot water cylinder is an essential part of a home water system and is responsible for producing hot water. Without its correct installation and operation, there can be permanent damage to the property and even threaten the safety of home occupants. A hot water cylinder is filled with a large amount of pressurized water, making it a potential fire and explosion hazard if improperly installed or maintained.
So, can I DIY a hot water cylinder installation?
Hot water cylinder installation is a complex job that requires detailed technical knowledge. It is illegal for anyone other than a qualified plumber to install a hot water cylinder because of the significant risk it poses to the well-being of both the property and its inhabitants.
Pressurised Hot Water
The most important reason it is illegal to install a hot water cylinder yourself is that these cylinders contain pressurized water. Pressure can build up inside the cylinder and if it is not managed or regulated properly, it can cause the whole system to overheat, switching off and potentially triggering safety features.
This could result in scalding hot water being released in your home and could even cause serious injury. (Here's what to do if you have a hot water emergency in your home.)
Modifying Plumbing and Electrical Fittings
Another reason why it is illegal to install a hot water cylinder yourself is that it may be necessary to modify existing plumbing and electrical fittings. These modifications can be complicated and will require expertise and experience that only a qualified plumber can provide.
Licensed plumbers will have the knowledge to safely work on high pressure systems, they have the tools required to do the job, and they also have the certification to show that the system is tested and safe.
In addition, licensed plumbers have access to the guidelines and technical documents that are applicable to hot water cylinder installations. These documents and regulations exist to keep people safe and provide recommend best practices and procedures.
Without the expertise of a licensed plumber, the installation may not comply with specific regulations and standards, and may not perform safely.
Finally, the installation of a hot water cylinder involves the provision of warranties from the manufacturer and the retailer. If the cylinder is not installed properly, the warranty may be voided and you will not be able to make a claim for damage or failure.
In summary, hot water cylinder installation should only be undertaken by a qualified and experienced plumber to avoid risk to the property and its occupants. A qualified plumber will have the skills, experience and permits to guarantee the installation is safe and compliant. Attempting to install a hot water cylinder without the correct qualifications and knowledge is illegal as it fails to adhere to industry standards and presents unnecessary risks.
