Geyser valve compliance
By Patrick Gordon of Calafrica ( technical @ calafrica . co . za )
How can I ensure that my geyser valve is still compliant after I have serviced it ?
What makes a product compliant ? There is a SANS manufacturing standard for most plumbing products . These standards prescribe a minimum performance standard , and they are tested and controlled by regular sample testing . When you procure one of these products you can be confident that it is going to perform according to the desired requirements .
So how do you know that when you have worked on one of these products it will still comply to these standards ? When servicing or working on a product you must use original components when replacing any parts . You will also have to know what the prescribed performance standard is for the product that you are working on .
If for instance you are working on a geyser valve you must test the valve for compliance before signing off on the job . So , you will have to check if the set pressure on the valve is within the desired parameters ( for a 400Kpa valve , between 280 and 340Kpa ). Next you must check if the relief function on the valve is working at the correct pressure ( 380 -400kPa ).
To summarise , if you have used original replacement parts and the valve is performing within the correct parameters , you can rest assured that the product that you have worked on still complies .
Contact the manufacturer of the valves that you are using for more specific instructions relating to the product that you are using . PA
