Geyser installation
Compiled by
Tanya Olckers
In this second instalment of our geyser series, we take a look at what goes into installing a geyser( or water heater.)
The most important part of geyser installation is that it be done by a competent, compliant and qualified plumber and electrician. Manufacturers take the utmost care in creating a compliant product: however, they are not responsible for incorrect installation on the part of the plumber or electrician.
Unqualified operators have caused untold damage, not just to the homes of clients, but to the overall reputation of the plumbing and electrical industry. What’ s more, you, the qualified plumber / electrician, may be called in to fix someone else’ s mess, which can lead to a great deal of frustration.
In step-by-step terms, installing a geyser can include the following steps: 1. Assess the installation area to ensure that there is sufficient space to install the water heater
2. Ensure the area is safe to work in and safe to mount the water heater 3. Turn off the water and electrical supply 4. Install the water heater in position and ensure it is securely mounted 5. Flush the cold-water supply line prior to connecting the water heater
6. Connect the relevant valves and piping, ensure the orientation of the drain cock is correct to avoid the pipes obstructing the flange area
7. Check that the pressure control valve is free from dirt and should be of the correct pressure rating
8. After completing the installation, fill the water heater and open one or more hot water taps to dispel the air from the system
9. Close all hot taps to bring water heater under pressure and check all plumbing connections for leaks
10. Installation diagrams and regulations must be complied with in all respects
11. The installation of a drip tray is required where water leaking from the water heater or connections could cause consequential damage
12. Have a registered electrician connect the electrical wiring
That last bit there – connect the electrical wiring – must be done by a qualified and competent electrician and must comply with SANS 10142-1.
Trouble shooting and maintenance
